Gang milling is a little more aggressive, requiring you to mount several cutters on a single arbor. This allows you to cut multiple surfaces or features using a single pass. This is a good method to use if you want to keep productivity high and not have to spend lots of time setting up and handling several individual machines. It’s great for mass production of identical parts, but would be overkill for low-volume needs.

Straddle milling involves mounting two milling cutters on an arbor and positioning them next to each other to create parallel slots, grooves, or surfaces on your chosen material. Because it has two cutting tools, it can essentially finish a piece in half the time. We see this process used often for keyway milling and machining flats on opposite sides of a shaft.

M35 cobalt and HSS drill bits are both made of steel alloy, but they have different compositions and properties. M35 cobalt drill bits contain 5% cobalt, which makes them harder and more resistant to heat than HSS drill bits. HSS drill bits are made of various elements such as chromium and vanadium, which give them high speed and durability.The main difference between M35 cobalt and HSS drill bits is how they perform in drilling hard metals. M35 cobalt drill bits can withstand higher temperatures and maintain their sharpness longer than HSS drill bits. They can also cut faster and smoother than HSS drill bits. However, M35 cobalt drill bits are also more brittle and expensive than HSS drill bits. They can break or chip easily if not used properly or if the material is too hard.HSS drill bits are more suitable for drilling softer metals, plastics, woods, or aluminum. They are also more versatile and economical than M35 cobalt drill bits. They can handle a variety of applications and materials with good results. However, HSS drill bits can lose their edge quickly and overheat when drilling hard metals. They can also produce more friction and wear than M35 cobalt drill bits.

A side milling cutter or end mill is used in side milling to shave thin layers of material from the side of a workpiece. This is the way to go for flat or contoured surfaces. Xometry’s very own Aaron (our marketing SVP) explains more about this milling process in the below video.

The term “milling” refers to the manufacturing process of using a circular cutting tool on the ends and sides of a material blank to make a finished part. That’s obviously just a very general summation; there are actually around 30 different types of milling operations, 15 of which (the most commonly used ones) we’ll go over in this article.Â

We hope this blog post has helped you understand the differences between cobalt and HSS drill bits with different point angles and choose the best ones for your project.

Calculating Spindle Speed (RPM) using Metric Cutting Speed: · 1000 x SMM · 3.14 x Diameter · 318 x SMM.

Angle milling makes beveled edges and angled features on parts. You can use specialized tools with this process, like tapered milling cutters that are cone-shaped or parallel-faced cutters that are flat but can be adjusted at a tilt to get the angle. To get the right tilt, you’d have to use a tilting arbor or four (or more) axis machine.

If you are looking for drill bits that can handle tough materials like stainless steel, cast iron, or titanium, you might be wondering which type of drill bits to choose: M35 cobalt or high speed steel (HSS). In this blog post, I will compare these two types of drill bits and explain their advantages and disadvantages. I will also recommend some drill bit sets that offer high quality and performance.

If you are looking for a drill bit that can handle tough materials and high torque, you might want to consider reduced-shank drill bits. These are drill bits that have a smaller diameter at the shank than at the cutting end, which allows them to fit into standard chucks while offering a larger cutting diameter. However, not all reduced-shank drill bits are the same. Three-equal flat shanks are reduced-shank drill bits that have three flat sides on the shank, which provide a better grip and prevent slippage in the chuck. They are also known as tri-flute or tri-flat shanks. These drill bits are ideal for drilling hard metals, such as stainless steel, cast iron, or titanium. They can also withstand higher torque and speed than round shanks.Round shanks are reduced-shank drill bits that have a smooth and cylindrical shank, which makes them easier to insert and remove from the chuck. They are also more common and cheaper than three-equal flat shanks. However, they have some disadvantages as well. They tend to slip and spin in the chuck when subjected to high torque or pressure, which can damage the chuck and reduce the accuracy of the drilling. They are also more prone to breaking or bending when drilling hard materials.To summarize, three-equal flat shanks are reduced-shank drill bits that offer more stability, durability, and performance than round shanks, especially when drilling hard metals. However, they are also more expensive and less available than round shanks. Round shanks are reduced-shank drill bits that are more convenient and economical than three-equal flat shanks, but they also have more limitations and risks when drilling tough materials. Depending on your needs and budget, you can choose the type of reduced-shank drill bit that suits you best.

If you have to make complex shapes and profiles on a surface, profile milling will be your best friend. It uses a tool with multiple cutting edges to make curves and angles and also has a ball tip that moves around, smoothing everything out. It sometimes (but not always) uses multiple axes to make the cuts. Getting an axis to cooperate in manual milling is, putting it mildly, impossible, so the process often is used with CNC (computer numerical control) machines. Profile milling is used to make dies, molds, and other parts with more detailed surfaces, like this:

The tool used in end milling has cutting edges on both its end and sides and can make things like slots, pockets, and contours. This method is very common because it is versatile. It’s a little like a drill bit that can cut straight down (plunging) but it can cut sideways, too. The below diagram will give you an idea of how it works.

It might not have a very interesting name, but plain milling is still a useful manufacturing method. It’s pretty basic, removing material from a surface using a flat, horizontal cutting tool, and it is used for making square or rectangular features. Here’s what that looks like:

Form milling makes contoured and detailed shapes on a surface with either a specialized milling cutter in the exact shape or profile you want or generic cutting tools (the latter is a somewhat repetitive process, similar to profile milling). It’s used a lot in automotive, aerospace, and mold-making, and many times with a CNC machine.

Shoulder milling removes material from the side of a workpiece (the “shoulder” or “sidewall”) with different cutting tools, like end mills, to make flat, 90-degree angles, like steps.

CAM (computer-aided manufacturing) milling can make parts that most humans would find impossible to create by hand. It’s an automated process, with the cutting tool being controlled by a computer. Human effort is only needed to design the digital blueprint for the part with exact instructions on how to make it in the language that it can understand (don’t worry, there are tools for this) and then feeding it to the computer and switching it on.

As you may have guessed, this milling method has been specifically designed to make gears and gear teeth (like the toothed wheels found in car engines or clocks). It’s done with gear hobbing cutters, or milling cutters, which remove material to make the gear teeth. For simple gears, manual machines are used, but for complex ones, manufacturers tend to go the CNC route.

Slot milling makes slots (like grooves or trenches) in any size with a slot cutter which looks like a circular saw blade. This will cut into the sides of the materials to do the job, but you can also use an end mill that cuts on its side and face. It basically carves out a channel in the material, making things like the slot your keys go into (keyways) and other grooves, like this one:

You’ll find that most milling types are self-explanatory with exactly what they do or how they work in their name, but here’s a little more info on each one.

Saw milling works with a large, thin, and round cutting tool that has lots of teeth (like a circular saw blade). This fairly quick and easy process is also known as “slitting” because it makes thin slits in a material. The blade of the tool can cut straight down in a vertical line or move along the surface for different types of cuts.Â

The spiraling threads you find on screws and bolts are made with thread milling. The tool has many cutting edges and is able to make threads in many different materials, in all different sizes, and can even tackle more complex designs. The thread milling cutting tool (which, by the way, is known for its durability and accuracy) rotates around the material along the thread path to cut the threads. Its capabilities are pretty much limited to making threads, but it does make them exceedingly well. Here’s a picture of a thread made by thread milling:

Face milling is beloved in the manufacturing world because it can be used to make accurate and smooth surfaces, even on larger pieces. It can make pockets and steps in metal by flattening the material and smoothing out the top. A face mill has cutting edges on its face, which is the part that looks like a disk, and these cutters work by shaving off material from a workpiece horizontally until it reaches the depth required (this will be preset by you).
