However, these drill bits don’t stay sharp for long and you will miss the advantage since the coating wears off the cutting edges. The event doesn’t use them to cut through metal with more than 1/8-inch in thickness.
Titanium: Titanium nitride coating drill bit is a great alternative to black oxide that also corrosion resistance and reduces friction. Extra benefits it brings are raising the surface rigidity and create a thermal barrier to lessen temperature buildup. As a result, it offers a longer service than black oxide. You can also use titanium drill bit for drilling locks.
Titanium drill bits drill faster comparing black oxide and its chips move through the flutes superiorly. But this drill bit expensive than the previous one and the coating wear off. However, a Titanium nitride coating drill is better for drilling in wood and metal.
