Cleveland Golf C15100 #10 Cobalt Drill Bit 135° Split Point TiAlN .1935

Drill Bit #10 Cobalt TiAlN

This Cleveland Golf C15100 drill bit is built for professional machinists and maintenance technicians who need reliable hole-making in tough alloys. The cobalt steel body resists heat and wear during extended drilling cycles. It fits standard chucks and works with both handheld drills and fixed machine tools.

135° Split Point Geometry

The 135-degree split point centres the cut instantly without a centre punch, reducing walk on curved or hardened surfaces. This geometry also lowers thrust force, which protects smaller drill presses and extends bit life. Right-hand cutting direction matches conventional tooling setups.

Decimal Size .1935 Inch

At .1935 inch diameter this bit covers the standard #10 clearance hole for many machine screw threads in steel, stainless and cast iron. The TiAlN coating adds lubricity and heat resistance for dry cutting, though deep holes in abrasive alloys may still require peck cycles or external coolant. Non-coolant-through design limits chip evacuation in blind holes beyond three diameters deep.
