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.

This simplified version of the feed rate formula is used in most machine shops. Again, it should be pointed out that these feed rates setting can only be used ...

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.

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.

A helix may be defined as a regular curved path. such as is formed by winding a cord around the surface of a cylinder. Helical parts most commonly cut on the milling machine include helical gears. spiral flute milling cutters, twist drills. and helical cam grooves. When milling a helix. a universal index head is used to rotate the workpiece at the proper rate of speed while the piece is fed against the cutter. A train of gears between the table feed screw and the index head serves to rotate the workpiece the required amount for a given longitudinal movement of the table. Milling helical parts requires the use of special formed milling cutters and double-angle milling cutters, The calculations and formulas necessary to compute proper worktable angles, gear adjustments. and cutter angles and positions for helical milling are beyond the scope of this manual.

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.
