53AJ90 Taper-Length Drill Bits

Bulk orders will be discounted, please contact us.

These drill bits have a TiAlN coating that withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. Coolant-through drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They are harder than high-speed steel or cobalt bits and require a rigid setup such as a drill press. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
