Taper Length Drill 1/4 Carbide MPN:652025011

The EgiAs coating on these drill bits resists oxidation at high temperatures and provides excellent hardness and heat resistance. The coating protects the bits from wear in high-speed drilling applications with steel, cast iron, and hardened steel with a Rockwell hardness of 35 to 50 HRC. These 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.
