12/20/2023 0 Comments Titanium or cobalt drill bitsTitanium bits are not made of titanium, but they come with a titanium coating. However, when the coating wears off with time, it starts losing efficiency. The titanium nitride coating does an excellent job dispensing the heat and thus protects the metal core from deforming. When you are drilling metal against metal, it will generate a lot of temperatures, so the drill bits come with some heat dispensing features. Titanium is a great metal when it comes to heat resistance. If you sharpen titanium bits that often, they become unusable quicker than not sharpening the bit. They generally have a shorter lifespan than cobalt drill bits. This is why, sharpening titanium bits is not very good, as that reduces the bit’s lifespan. That reduces the drill’s heat resistance and may warp or deform the tip. Hence, they need a bit of sharpening from time to time in order to maintain their drilling efficiency.Īs the titanium drill bits come with titanium coating, sharpening them can wear off that coating and expose the softer metal core. Sharpeningĭrill bits tend to get blunt which can adversely affect the drilling capabilities. The coating also helps resist heat when drilling through tough materials such as metal. The titanium nitride coating helps to drill smoother and resists the bit from corrosion. Hence, the drill bit is made of carbon steel alloy with a titanium nitride coating on top. Moreover, titanium is known to be brittle, so there’s a chance that the drill bit will break when in heavy use. Titanium is an expensive metal, so making a drill bit with it might soar up the cost. Although the drill bits are named titanium, they do not contain titanium.
