Best Seller 52 Stub Drill Bit Cobalt Split Point D/ASTCO52 (12 / Pkg.)

Specs

Size: #52

Material: Cobalt alloy

Tip: Split point

Length: Stub-length drill bit

Packaging: 12-pack

Features

Split-point tip minimizes walking and centers the drill for accurate hole starts in hard metals.

Cobalt alloy provides higher heat resistance and longer edge life than standard high-speed steel bits, suitable for drilling hardened steels and stainless steels.

Stub-length design increases rigidity and reduces flex, improving hole concentricity in restricted-access or tight-tolerance applications.

Precise diameter and flute geometry support efficient chip evacuation and cleaner holes in metalworking tasks.

Ideal for fabrication, maintenance, and repair work where repeated drilling in tough materials is required.
