Cleveland C70252 Screw Machine Drill Bit 5/64 in Hss

Product Description

The CLEVELAND C70252 is a screw machine length drill bit designed for high-speed drilling in metal fabrication and machining applications. Built from high-speed steel with a bright/uncoated finish, this bit features a 135-degree split point that reduces walking and allows faster penetration without a center punch. At 5/64 inch (0.0781 inches) in diameter and 1-11/16 inches overall length, it is engineered for use in screw machines, CNC lathes, drill presses, and hand-held power tools where shorter flute length provides added rigidity. The web-thinned parallel web configuration reduces thrust and improves chip evacuation in close-tolerance work.

This bit is suited for drilling alloy steel and aluminum in production and maintenance environments. Its screw machine length profile makes it a practical choice for tight clearance situations or when extra bit stability is needed. Licensed HVAC techs, plumbers, electricians, and general metalworkers will find it useful for sheet metal, electrical enclosures, and mechanical assembly tasks. The straight-cylindrical shank fits standard drill chucks without adapters, and the right-hand cut matches conventional drill press and power tool spindle direction.

Key Features

• 135-degree split point reduces drill walking and lowers required feed force
• Web-thinned, parallel web construction improves chip clearance and reduces thrust
• High-speed steel construction handles alloy steel and aluminum at production feed rates
• Screw machine length body provides greater rigidity compared to jobber-length bits
• Bright/uncoated finish allows easy visual inspection for wear during service
• Meets ASME B94.11M and NAS 907 Type C standards for dimensional accuracy

Compatibility

Designed as a screw machine length replacement drill bit for use in standard straight-shank drill chucks; primary workpiece materials listed are alloy steel and aluminum.

Installation Notes

This bit is installed by trade professionals and machinists using standard drill press, CNC, or hand-held power tool equipment. Secure the straight-cylindrical shank firmly in the drill chuck before operation and confirm the tool is powered down before bit changes. Use appropriate cutting fluid or coolant for extended runs in steel — note this bit does not support through-coolant delivery. Follow shop safety protocols and applicable OSHA standards when operating rotary cutting tools.
