Cleveland C15080 Screw Machine Drill Bit 17/32 in Cobalt

Product Description

The CLEVELAND C15080 is a screw machine length drill bit designed for high-production drilling in demanding shop environments. Built from M42 cobalt high-speed steel, this bit handles tough alloy steels, aluminum, and other hard-to-machine materials that would wear out standard HSS tooling quickly. The 135-degree split point starts on contact without a center punch, reducing walking and improving hole accuracy. At 3-7/8 inches overall length and a 17/32 inch diameter, the screw machine length profile keeps the bit rigid, reducing deflection in turret lathes, screw machines, and short-stroke drill presses. Installation and use are handled by machinists, toolroom operators, and CNC setup techs.

The C15080 belongs in tooling setups where stub-length rigidity is required. The straight-cylindrical shank accommodates standard drill chucks and collet holders sized for 0.5313 inch shank diameter. Primary workpiece materials include alloy steel and aluminum. The parabolic flute geometry evacuates chips efficiently, making this bit well suited for deeper holes in continuous-feed applications. Conformance to ASME B94.11M ensures dimensional consistency across production runs.

Key Features

• M42 cobalt steel construction resists heat buildup in high-speed or dry drilling applications
• 135-degree split point starts without center punching and reduces thrust force
• Parabolic flute geometry with web-thinning improves chip evacuation in deeper holes
• Screw machine length body provides maximum rigidity and minimizes deflection
• Right-hand cut with straight-cylindrical shank fits standard chucks and collet holders
• Diameter tolerance held to +0.0000 to -0.0012 inches per ASME B94.11M

Compatibility

Designed as a direct-fit replacement or production tooling choice for any setup requiring a 17/32 inch screw machine length drill bit with a straight-cylindrical shank in the 0.5000 to 0.6000 inch decimal inch size range.

Installation Notes

Installation is performed by machinists or toolroom personnel. Secure the straight-cylindrical shank firmly in the chuck or collet holder before operation and verify runout before drilling production pieces. Power down and lock out the machine spindle before changing tooling. Refer to your machine tool manufacturer guidelines and applicable shop safety standards when selecting feeds, speeds, and cutting fluids for the workpiece material.
