Power through stainless and hard steel with this 1/2-inch cobalt steel drill bit. Start clean and on center with a 135-degree split point, then keep cutting as heat rises thanks to a precision-ground, gold finish that resists friction and wear. Fit it into common drills with the reduced 3/8-inch shank and keep jobs moving.

Key Features

• Cobalt steel: Hold hardness under heat for longer cutting life in tough alloys.
• 135° split point: Prevent walking and bite fast with less push.
• Jobber length: Balance reach and rigidity for accurate holes.
• Reduced 3/8" shank: Run a 1/2" bit in standard 3/8" chucks.
• Precision-ground, gold finish: Lower friction for smoother chip flow and cleaner walls.
• Lightweight single: Carry just 0.2 lb and replace only what you need.

Applications

Tackle stainless hardware, hard steel plate, angle, and bolts without constant resharpening. Move from metal to wood or plastic when the job calls for it, keeping one dependable bit on hand. Use it in a hand drill or drill press when accuracy matters.
