Cleveland Cobalt Drill Bit 1/8 Inch

This Cleveland Golf cobalt drill bit measures 1/8 inch with a 135-degree point angle. The TiAlN coating and parabolic flute design support efficient chip removal. It suits metalworkers and maintenance technicians who need a high-performance jobber drill for general-purpose drilling tasks.

Upgrade From Standard High-Speed Steel Bits

The cobalt steel construction and TiAlN finish increase wear resistance compared to uncoated high-speed steel alternatives. The 135-degree notch point reduces walking on hard materials. The jump is worth it when drilling stainless steel or other tough alloys that dull standard bits quickly.

Straightforward Chuck Installation

The 1/8-inch shank fits standard drill chucks without adapters. Right-hand cutting direction matches common power drills. Problems usually arise if the workpiece is not clamped securely or if cutting speed and feed are not matched to the material, leading to premature wear or breakage.

Questions about this item

What shank diameter does the 1/8-inch drill bit use for the chuck?

The shank diameter is 1/8 inch, matching the drill bit size for a direct fit in standard three-jaw chucks.

How do I start the hole correctly with the 135-degree notch point?

Apply steady pressure at low speed; the 135-degree notch point self-centres without a centre punch, preventing walk on hard materials.

When should the TiAlN coating be considered worn and the bit replaced?

Replace the bit when the gold TiAlN coating has worn through to the cobalt substrate at the cutting lips, indicating lost heat resistance.
