Especially it can drill hard metal such as bronze, cast iron, stainless steel, and titanium. Usage of Cobalt Drill BitsĬobalt drill bits are good for metal and wood. These coatings are applied on the drill bit in order t o improve the service life, and thermal resistance and reduce the friction between the drill bit and the cutting surface. TiAlN – Titanium aluminum nitride (Violate color coating).TiCN – Titanium carbon nitride (Grey color coating).TiN – Titanium nitride coating (Golden color coating).Titanium, Aluminum, Nitrogen, and Carbon are used as the mixed compound layer on the drill bit. Normally, coated cobalt drill bits are different in color. Coated Cobalt Drill BitsĬobalt drill bits are coated with titanium compounds in order to improve their physical characteristics. That ability is due to the mixing of cobalt. Of course, cobalt drill bits have more attractive features. If something is going to take a long time to drill, these drill bits can be used to get it done in a short amount of time without a lubricant in between. Suitable for use in high-temperature conditions due to high boiling and melting points. The melting point of Cobalt is 1495☌, and its boiling point is 2927☌. This is because they have a tendency to break higher than M35 drill bits. M35 drill bits can be mounted to handheld devices without fear, but M42 drill bits cannot be used as such. M35 Cobalt drill bits contain approximately 5% cobalt alloy, and M42 cobalt drill bits contain approximately 8% cobalt alloy. Among those types of drills, M35 and M42 are the most common Cobalt drill bits. This composition helps to give a high resistance.īased on the percentage of cobalt in the drill bit, can be identified the different cobalt drill bits. Cobalt was mixed typically between 5 – 8%. Cobalt drill bits are a combination of steel or another alloy mixed with a small percentage of cobalt. Cobalt Drill Bit M35 and M42 Cobalt Drill BitsĬobalt drill bits are not made from pure cobalt.
