This 54-second demo shows a 3mm TTP HARD cobalt drill bitcutting throughHARDOX 450 plateusing a hand drill.

CUT-IT paste applied before drilling keeps the bit cool and lubricated.
At 15 seconds, when the drill begins to squeal, more CUT-IT is applied — instantly reducing friction and letting the bit glide through.
Long, continuous metal swirls are produced, showing an efficient cut and excellent bit sharpness.

This is a clear demonstration of how small cobalt drill bits + CUT-IT paste handle extreme abrasion-resistant steel.
