![]() ![]() With titanium nitride, you have to remember it only coats the bit. For metal drilling, we recommend these as the bare minimum.

The result is a more compact bit with a similar drilling depth. However, they also extended the flutes lower towards the shaft. Milwaukee countered this by making them a bit shorter than some others we’ve seen. The trade-off is that these bits thin out more towards the tip. Their unique design not only helps them drill efficiently, but it also aids in cooling. How quickly? About 30% faster than most other 135° split-tip bits we tested against.
