The cut or profile you want to accomplish will guide your decision regarding the type of carbide burr to use. The many shapes of carbide burrs are listed below:

On the other hand, the double-cut carbide burrs, also known as cross-cut or diamond-cut because of the two flutes that are cut across one another, are typically used on all non-metal materials, including soft steel, aluminum, wood, and ferrous and non-ferrous metals. The finish is smoother with the double-cut carbide burrs than with the single cut because they make smaller chips when they remove the material.

PCD (Poly – Crystalline – Diamond) is, unlike single crystalline diamond, produced synthetically by sintering together many (Poly) diamond particles, usually in the size of 2 to 30 microns of a meter, with a metal binder (usually Cobalt) at high temperature and high pressure. The rate is 90-95% diamond particles and the rest is Cobalt.

Rotary files, commonly known as carbide burrs, are tiny spinning tools used for cutting. Theoretically, carbide burrs are similar to files, but they cut and finish metal workpieces by rotating rapidly as opposed to cutting in a linear motion. Sharp edges, burrs, and superfluous material can be shaped, chopped, ground off, and removed with carbide burrs. Carbide burrs are rigid and strong, thus there are fewer vibrations and hence no bends.

Try not to hold your die grinder bit stationary for too long when using it. This will stop the burr from poking and burrowing into the material, leaving ugly markings and roughness. To give your work a nicer finish, end with an "up" stroke. Soft cast iron can be easily unclogged by using a carbide burr.

All types of wood, plastics such as glass fiber reinforced plastic (GRP), carbon fiber reinforced plastic (CRP), fiberglass, acrylic, and metals such as cast iron, aluminum, and steel are among the materials that use tungsten carbide burrs. Carbide burrs have a long lifespan without breaking or shattering, making them appropriate for soft metals like silver, platinum, and gold. Titanium, nickel, cobalt, zinc, and other metals are among the others.

(Chemical Vapor Deposition) is a process of coating Nano diamond particles on a Tungsten carbide substrate applying a layer thickness of 6 to 16 microns of a meter. The tungsten carbide substrate has to contain low cobalt content, such as 6% an d has to go through specific surface treatment. The treatment reduces cobalt content in the outer layer, exposing the diamond edges, in order to create sufficient adhesion between the diamond coating and substrate.

While countersinking is considered a manual operation, the countersink body is made from steel, mainly due to the thread connection. Steel cannot be coated with CVD diamond; therefore, most countersinks in the market for composites are PCD. PCD segments are brazed to the steel body of the countersink. Full carbide countersinks which can be coated are rarely seen, due to the fact that grinding the thread on the tungsten carbide body is a complex task.

Carbide burrs are crucial if your task requires shaping, grinding, or cutting—especially with air tools. They may work with a variety of materials, including wood, ceramics, fiberglass, steel, iron, and titanium. Carbide burrs, also known as die grinder bits or rotary files, are available in a variety of shapes, making it possible to customize the burr according to the work. The following information will help you use them effectively in your project.

Carbide burrs are used in a variety of fields, including metalworking, dentistry, the automobile, and aerospace sectors, among others. They are frequently used in various industries for metalwork such as carving, cylinder head porting, grinding, deburring, casting, chamfering, welding, jewelry making, wood carving, model engineering, and tool building.

The speed at which you utilize your carbide burr set in your rotary tool depends on the shape being formed and the material to be worked on. However, you should begin slowly and pick up speed as you proceed. Speeds over 35,000 RPM are unacceptable.

PCDtool meaning

Milling operations involve interrupted cutting of the material, where each end mill tooth is engaged with the material and exiting it in one tool revolution. Each time the cutting edge enters the material, the “hammering” effect damages the cutting edge of the tool. Looking at the table above, PCD tools are more likely to withstand the “hammering” effect in milling. In CVD diamond coated tools, the CVD coating eventually delaminates and only the tungsten carbide substrate is left. In the PCD, even if some fracture occurs, the diamond is solid and therefore keeps the same characteristics. There is a concern, though, about geometry limitations with the PCD. For instance, when a particularly long flute length is required, or when specific tool geometry is required, e.g. porcupine router, the CVD diamond tool has an advantage.

Die grinders, high-speed engravers, and pneumatic rotary tools are examples of air tools that frequently employ carbide burrs. Other examples are hobby rotary tools, flexible shafts, pendant drills, and micro motors. Remember to use a handpiece that doesn't wobble at all times.

In the production of aerospace and turbine parts as well as in the transformation of metal, carbide burrs are frequently employed for deburring, weld preparation, chamfering, edge breaking, and removing material from intricate and challenging-to-reach places.

For long-term performance, a carbide is always a preferable option because HSS burrs will start to weaken at higher temperatures.

In this article, we’ll try clarifying and shedding more light on a dilemma confronted by many end users of cutting tools to machine composite materials, when they are required to decide which type of tool to use for their application. There are mainly two types of diamond cutting tools for composites: PCD tools, where the cutting edge is built from a PCD segment of a specific size and shape and CVD diamond coated tools, where the tool’s edge is completely built in a grinding operation and later coated with CVD diamond.

Single-cut carbide burrs, commonly known as one flute, will efficiently remove the material with a smooth finish if used with right-handed spiral flutes. They mostly work with stainless steel, cast iron, hardened steel, and ferrous metals like copper and iron. They are appropriate for heavy stock removal, milling, and deburring.

Burrs made from high-quality carbides are manufactured by machine. As Tungsten Carbide is extremely dense (compared to HSS), it is suitable for far more difficult projects than HSS. Carbide burrs are also more heat resistant than HSS, so they can run hotter longer.

In drilling operations, the cutting edge has constant contact with the material, unlike milling, therefore the cutting edge is less likely to chip or fracture. Taking that into account, with a combination of hardness and sharpness, CVD diamond drills perform better in regard to minimizing the delamination at the hole exit. This is a major concern in the drilling of composites in highly engineered parts, such as Aerospace. When delamination is the failure criteria, there is no doubt that CVD drills outperform PCD drills. However, when hole diameter is the failure criteria, then the PCD drill will “survive” longer than CVD drills.  The reason for this is due to the fact that the CVD diamond is a coating. When it eventually delaminates from the tungsten carbide, edge wear accelerates rapidly. The PCD, on the other hand, as said, is a solid diamond. Wear development rate is almost constant. Another example where PCD may have an advantage is the drilling of stack material like CFRP/Al, where the exit hole is in the Aluminum. Delamination is a non-issue in this case, therefore PCD would be first choice, since it will hold longer and can also be reconditioned a few times. Another advantage of the CVD diamond drill would be design flexibility, while comparing to standard wafer drill, where PCD segment dictates geometry. On a Fullnib PCD drill, however, there is no geometry limitation and design flexibility is the same as in the CVD diamond drill as long as PCD nib height (which is limited) does not create other limitations.

Use carbide straight shank drills or carbide micro drills when drilling holes in difficult metals. A carbide end mill, carbide slot drill, or carbide router can be applied to cut slots, route, profile, contour, counterbore, and ream. A diamond burr is used to cut and shape glass or stone.
