Holemaking / Drill Bits

Holemaking tools are designed for precise drilling and reaming applications in metalworking, automotive, aerospace, mold making, and machinery industries. High-performance drill bits offer strong hardness, sharp cutting edges, and smooth chip removal. This allows faster drilling speed and reduces tool wear. They are available in different sizes and lengths to suit various needs, and can be used on materials such as steel, stainless steel, aluminum, high-hardness steel, and other alloys. These tools improve productivity and ensure accurate hole dimensions, making them a vital component in modern precision manufacturing.

Speed Tiger is a leading manufacturer of carbide drill bits. We also provide drill bits for hardened steel.
