Typically used in electronics and medical equipment manufacturing, micro-size carbide drill bits are used for drilling very small holes and often have tight dimensional tolerances.
Super-life TiAlN (titanium aluminum nitride) coating withstands high temperatures and protects the bit against wear when drilling at high speeds and high feed rates in difficult-to-machine materials. TiAlN-coated tools are suitable for dry or semi-dry machining applications.

The best choice for high-temperature drilling applications with high speeds, the AlTiN (aluminum titanium nitride) coating on these bits is suitable for dry or semi-dry machining applications in hard or abrasive materials.
