They’re capable of drilling the initial hole and then countersinking or counterboring it. Variations on this type are available for drilling all materials.Īll-in-one: These bits have a hole in the middle that accepts a smaller diameter (pilot) drill bit and often a depth stop. They are designed to countersink an existing drill hole. Standard: These bits have a cone-shaped tip and cutting flutes that extend down the sides. When the drill bit wears out, it can't be resharpened or recoated it has to be thrown away. The drawback with TiN is that it's a coating rather than part of the metal. These are efficient at cutting because they’re very hard, low friction and good at dissipating heat. TiN: Countersinks described as TiN use a titanium nitride coating (a type of ceramic). You'll find them in many professional machine shops, but they’re expensive. This creates the hardest and strongest of all drill bit types. M2: This is high-speed steel with tungsten and molybdenum added, which makes for a much harder material that’s better suited to drilling metal.Ĭobalt: Another improvement on HSS is made by adding cobalt. These bits are less prone to rust and create less friction, which means greater efficiency. Heat-treated HSS: Standard HSS can be improved by heat treating, which gives it a black oxide coating. The material can also cope with aluminum and other soft metals, but it struggles with steel and cast iron because it tends to overheat and dull quickly. HSS is excellent at cutting wood as well as most plastics and composites. It's a proven material used for all kinds of cutting tools and forms the base for all types of countersink drill bits. High-speed steel: The cheapest countersink drill bit sets contain bits made of standard high-speed steel (HSS).
