Cleveland C15069 Screw Machine Drill Bit 23/64 in Cobalt

Product Description

The CLEVELAND C15069 is a screw machine length drill bit designed for high-performance drilling in tough materials. Built from M42 cobalt high-speed steel, it handles alloy steel, aluminum, and other demanding workpiece materials without rapid wear. The 135-degree split point geometry starts on contact with no center punch required, and the web-thinned, parallel web configuration reduces thrust and chip packing. At 3-1/16 inches overall length with a 1-3/4 inch parabolic flute, this bit is suited for close-quarters drilling on drill presses, CNC machines, and production setups where stub-length rigidity matters. It meets ASME B94.11M standards under ANSI specification designation.

The C15069 is built for production and maintenance environments where hole quality and tool life in hard metals are priorities. The screw machine length format is a common choice on turret lathes, gang drills, and CNC machining centers where extended reach is unnecessary and rigidity is critical. Primary workpiece materials include alloy steel and aluminum. The right-hand, two-flute parabolic design promotes efficient chip evacuation in both through-hole and blind-hole applications. This is a single-piece unit sold individually.

Key Features

• M42 cobalt steel construction for extended tool life in alloy steel and aluminum
• 135-degree split point with web thinning reduces entry thrust and eliminates walking
• Parabolic flute geometry improves chip evacuation and reduces heat buildup
• Screw machine length (3-1/16 inches OAL) provides rigidity in production drilling setups
• Straight-cylindrical shank at 0.3594 inches diameter fits standard drill chucks and collets
• Meets ASME B94.11M standards under ANSI specification

Compatibility

Designed as an OEM-style replacement or direct-fit production bit for standard drill chucks and collets accepting a 0.3594-inch straight-cylindrical shank, consistent with Cleveland Series 2175A screw machine length tooling.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians. Secure the shank fully in the chuck or collet and verify runout before drilling. Power down and lock out the machine before changing or inspecting bits. Do not exceed the spindle speed and feed rate appropriate for the workpiece material and bit diameter per the machine manufacturer guidelines.
