Product description

Why is the 135° split point design important?

The 135° split point ensures faster penetration with minimal pressure, reduces "walking" (slipping) on curved surfaces, and provides self-centering accuracy. This design is ideal for precision drilling in hardened metals.
Are these drill bits suitable for woodworking or DIY projects?

Yes! While optimized for metals like stainless steel, the bits also work efficiently on wood, hard plastics, and other non-metallic materials. Their sharp edges and twist design clear debris quickly for smooth drilling.
