Before you settle for a lathe tool for machining, take note of the workpiece material being machined. As a general rule of thumb, your lathe-cutting tool must be tougher than the workpiece material.

These tools move toward the chuck from right to left when machining. In this setup, the chuck holds the workpiece on the left side of the machine. Usually, you’d find the end cutting edge facing the left side and the relief angle facing the workpiece on the right.

This speed and efficiency in turning or cutting steel and workpiece materials during fabrication reduces the fabrication cost by about 60%. You can confirm this estimate by calculating the overall machining cost alongside the tool’s cost.

Generally, carbide tools or cutters have a steel body or removable blades with edges brazed with carbide. This carbide tipping helps them to produce excellent surface finishes and not wear off with steady machining.

So, it’s important to consider the type of material you’re cutting or turning to help you determine the speed or feed rate you’ll need. Not only speed or feed rate but also the complementing lathe-cutting tool to do the job.

Lathe-cutting tools or turning tools are special tools we use to drill or knurl a workpiece during machining. These tools have different shapes, textures, forms, and materials that contribute to producing excellent fabrications or finishes.

Creating quality fabrication and finishing begins with choosing the right lathe-cutting tools. Here are some things to note when selecting lathe-cutting tools for optimal performance and efficiency.

Secondly, the coating gives the lathe tools some mechanical advantages over forces that could deform them. Examples of such forces are heat and friction during machining. To sum it up, ensure you choose lathe tools with proper coating. Or even so, coat them yourself.

The heel is usually the rounded part that joins the flanks and the base of the lathe-cutting tool. You can easily see how their shape affects the overall lathe-cutting tools’ geometry and performance.

Also, the shapes and forms of these lathe-cutting tools determine how we use them during machining. This also makes each tool unique. For instance, we use chamfering tools with 45-degree angles or cylindrical radii to drill press or machine the center of a workpiece. The point is that we can only use this tool with such a structure for that purpose or operation.

Fortunately, we can measure this hardness using a Brinell hardness tester. The other method is using industry-standard alloys or materials like carbide-tipped cutters or cemented inserts, diamond or CBN cutters, etc., to cut or finish corresponding workpieces.

The reason for this high-speed cutting is CBN’s inertness to carbon or any alloy with carbon. Additionally, CBN is more heat resistant than carbide and high-speed steel cutters combined. Amazingly, it is more heat resistant than diamond cutters too.

Additionally, this steel upgrade contributes to HSS’s toughness and ability to withstand high temperatures without deforming—a property it gets from the various alloys that make up its composition.

High-speed steel lathe-cutting tools were introduced in the late 1940s to replace the high-carbon steel. The upgrade in HSS’s chemical makeup allows it to cut and turn a workpiece faster and more efficiently than high-carbon steel. This is also why we call it a “high-speed steel lathe-cutting tool set.”

A single-body tool, just like its name, has all its parts in one piece. This means their edge-cutting parts, tool angles, shank or bar, and every other essential lathe-cutting tool part are in one file.

With grooving tools, you make furrows inside or outside a cylindrical workpiece. Depending on the tool configuration, you could make thinner or wider grooves or furrows on workpiece surfaces.

For instance, harder or thicker materials require more torque or force from the rotary machine to give a fine cut. This translates as a lower speed or feed rate because the rotary tool tends to slow down when it comes in contact with a hard or thick material. Conversely, materials with lesser diameters or hardness cut very well at faster speeds.

We use a chamfering cutting tool to smoothen surfaces or remove burrs or sharp edges from a workpiece. This process is called chamfering because the deburred material and form tool assumes the position of a chamfer or bevel at 45-degree angles. Chamfering makes the resulting material safer to hold and manipulate during other machining processes.

Finally, you should consider the type of lathe machine you’re working with. We have two types of lathe tools machines: manual and automated CNC lathes. The type or shape of the lathe-cutting tool you may need would depend on this.

These tools are also called center lathe-cutting tools. They may have equal angles of 45 degrees on the left and right hands of the main cutting edges. You may or may not find rake angles. Examples are chamfering tools used to make smooth surfaces.

Different lathe tooling experts may call shank different names. Some would say a shank is where a lathe tool connects to the holder. Others would argue that a shank is the body of a lathe-cutting tool.

Regarding longevity, carbide-cutting tools for lathes can arguably last about 99 times longer than high-speed steel tools. This is because they can maintain a sharp or harder cutting edge regardless of the temperature or speed of the machining. We further classify them into carbide-tipped tools and cemented carbide inserts.

Furthermore, making these furrows requires high precision and accuracy, so we use grooving tools for CNC turning machining processes rather than manual machining.

Carbide-tipped tools are usually fixed or holistic. You may need to change the entire cutter or blade after it becomes blunt. On the other hand, you can rotate the cemented carbide inserts when one part is worn, thereby maintaining its size and quality finish longer.

By knowing the classification of lathe-cutting tools, it becomes easier to determine which lathe-cutting or turning tool is which in the factory.

Contrary to popular opinion, coating isn’t all about using oil or acrylic paints on your material. It could also mean applying inert elements or compounds to lathe tools to avoid natural wear. Examples are cubic boron nitride or carbide.

The third way to identify cutting tools is by their structure. Usually, these tools may come in a single holistic form or combine different materials in one tool. They include single-body tools, clamped tools, and welded tools.

For this reason, you’d often find different cutting tools for lathe in various shapes, sizes, forms, appearances, etc. Each characteristic was intentionally created to facilitate quality machining of workpieces in the shape and operation you want.

Over the years, lathe-cutting tools have become life-saving equipment in various industries. Whether you operate these tools or want to procure one for your facility, this guide will show you everything you need to know about them. Read on!

Either way, the definitions point to the same meaning. You should know that the area of a lathe tool without any special styling or face for machining is the shank. It could be its body or handle. Usually, shanks maintain their positions in a tool holder through friction.

For instance, the general formula for making HSS is Fe-C-x. Where Fe and C are the primary components of the HSS steel. On the other hand, x may represent Tungsten, Vanadium, Molybdenum, Cobalt, or a pair of these elements.

Although, the tools used in a CNC machine would be the same as those used in a manual machine. The difference, however, would lie in their shapes and sizes. A custom CNC machine may require different sizes of cutting tools that fit into the machine’s architecture. The same logic applies to the manually-controlled machines.

Nevertheless, machinists could adjust the single-body tools’ shape, size, or architecture depending on the need or intended product. Examples are some lathe-cutting tools for brass.

Cutting speed and feed rate are other important factors because we cannot cut or finish all materials at the same speed. Usually, this depends on the type of material you’re working with.

One of the reasons we use ceramic lathe-cutting tools is their chemical stability and ability to give off rough and fine finishes. Plus, they are very heat resistant and do not wear easily.

Boring tools are single-point cutting tools used to elaborate an existing opening in a workpiece. With them, you can create a conical or cylindrical workpiece or finish an existing one. Their parts include a boring bit or tip, an arbor, and a boring bar (shank) that fits into a tool holder.

A lathe thread-cutting tool is usually edged with carbide or high-speed steel and used to make thread-like apertures in the internal or external surfaces of workpieces. This is usually a finishing operation after turning or boring a cylindrical workpiece.

For this reason, we’d need tools derived from certain materials to turn or finish these workpieces excellently. For instance, carbide lathe-cutting tools are best suited for higher speeds and temperatures because they withstand them better.

As the name implies, the left-hand metal lathe tool removes or cuts off chips while moving from left to right. In this case, the workpiece is on the right side of the machine. Also, the end or main cutting edge angle faces the right side.

This is the rounded part of the lathe-cutting tool where the main cutting edge meets the auxiliary cutting edge. It almost forms a right-angled triangle, only that the point of intersection is rounded to give it a nose radius.

During fabrication, we machine various metals and non-metals. However, the varying mechanical and chemical characteristics of these workpieces necessitate different cutting tools.

We also call the cutting edge the tool lips. Usually, we braze this part of the lathe-cutting tool with diamond, carbide, graphite, CBN, etc., coating. They are the points that shape or turn the workpiece material or remove chips during machining.

One way to prevent quicker tool failure or help your lathe tools last longer is by coating them. Generally, for any material, coating is a sure way to prevent natural wear action or rust caused by humidity, water, or any natural chemical actions on the tool.

Turning is one of the most common machining operations in many fabrication factories. It’s simply a process used to remove excess material from a workpiece. This could be a rough turning operation where you remove excess materials to reveal the workpiece’s first view. Then again, it could be a fine-turning operation that produces an excellent sheared product and finishing.

The secret to producing quality finishes is picking the right cutting tool. Hopefully, this guide gives you every information you need to identify or make custom lathe-cutting tools that fulfill your machining needs regardless of the type of machine you use.

As a rule of thumb, avoid burning the cutting edge of lathe tools to help them last longer. After each use, ensure you examine the edges and properly maintain them before the next use.

A facing tool is a turning tool we use to finish workpieces. They are usually coated with carbide, CBN, or HSS and give off fine finishes. Concerning architecture, facing tools are mounted perpendicularly to the rotating workpiece. The relief angles prevent other parts of the facing tool from interfering with the workpiece or machining process.

Knurling tools are used to insert criss-cross patterns on a workpiece. After knurling, you can hold the material better as there is increased friction between the holder and the material.

Like CBN, ceramic lathe tools can cut harder materials at high cutting speeds and feed rates without any coolants. A common type is the ceramic insert turning tool. We usually screwed this type into a tool holder. Like cemented carbide inserts, we rotate the sides to maintain the tool’s finishing quality longer.

Besides the workpiece materials used during machining, you should also consider the type of finish you need. This could be a turning, cutting, knurling, facing, or shaping operation.

Sometimes, we call lathe-cutting tools turning tools because they all undergo similar primary operations. Let’s say that “turning tool” is the generic lathe tools name. Nonetheless, other tools have some uniqueness, giving them their properties and names. For example, a thread-cutting tool produces thread-like objects like screws or bolts.

Whatever the operation, there is always a corresponding lathe-cutting or turning tool that complements it. Typically, we say that lathe machining is versatile. Nevertheless, it’s the lathe-cutting tools that make it so.

Another class of lathe or turning tools are those with different feed directions. To be clear, a feed direction is the position of the cutting edges inserted into the turret or tool holder during machining. Or the part of the cutting edge that performs the machining or finishing on a workpiece.

Every single-point lathe-cutting tool has two flanks. You could spot the first flank, a.k.a the major flank, adjacent to the side or auxiliary cutting edge. All the same, you should find the second or minor flank adjacent to the end or main cutting edge.

These tools are usually replaceable or upgradeable. They include inserts of tools, usually with multiple cutting edges screwed or clamped onto a shank to form a whole piece. Examples are cemented carbide insert tools.

These x-elements give HSS more characteristic toughness and temperature resistance. Plus, they will be useful to you when finalizing which HSS tool you need.

Some of the lathe-cutting tools we categorize based on material types include high-speed steel, carbide tools, diamond, ceramic, and cubic boron nitride. Let’s see more on them below:

The face is the part where the chips usually fall onto during machining. It’s intentionally curved or spaced to allow more chips to flow onto it before falling off so as not to cause clogging on the cutting edge.

Common tools used for this operation include screw tabs or thread-cutting dies. Large-scale or branded production companies may use a cold or hot forging process that capitalizes on the temperature differences of a workpiece material to strengthen its properties.

These tools have different end and side-cutting edges or parts welded or soldered together. This could enhance the lathe-cutting tool’s turning or finishing quality. Many boring and grooving tools fall into this category.

Thread-cutting dies are examples of lathe tools for metals. On the other hand, the screw tabs may act as a wood lathe tool or thread tool for lathe materials like glass or plastics.

Another way to recognize lathe-cutting tools in CNC lathe-cutting tools factories is by what we can do or achieve with them. Some of the lathe tools we categorize by their operation include turning, thread-cutting, chamfering, forming, facing, boring, grooving, and knurling tools.

A form-cutting lathe tool is another common tool we use to fabricate or weld materials. As the name implies, you can use form tools to forge or design workpieces into desired designs or shapes you need. Other common activities we use form tools for include turning, presswork, and stamping.

Diamond lathe-cutting tools are the greatest lathe-cutting tools for high-precision cutting and finishing. Usually, we feature them as single-point cutting tools because of the cost and availability of diamonds. This single-point nature is the reason for its common name, single-point diamond turning (SPDT) or single crystal diamond cutting (SCDC) tool.

A cubic boron nitride, also called CBN nanopowder, is arguably one of the strongest materials on earth—second to diamond. When used to make lathe-cutting tools, it can cut or finish metals or metallic alloys at high speeds without requiring any cooling process in between or afterward.

Now that we’ve established the above concepts, let’s also look at the mechanical makeup or parts of lathe-cutting tools with which they produce quality machining.

Also, we can use knurling tools to repair originally knurled and faded materials. The architecture of a knurling tool is a pattern of crossed, straight, or angled lines, which, when used to machine a workpiece, gives it characteristic knurls or knots.
