Cleveland C71023 Jobber Drill Bit 23/64 in Hss Oxide

Product Description

The CLEVELAND C71023 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with an oxide coating, it resists heat and wear during extended use. The bit measures 23/64 inches (0.3594 inches decimal) in diameter with a 4-7/8 inch overall length. A 118-degree standard point angle provides reliable center-starting on flat and curved stock. The spiral, regular-helix flute geometry evacuates chips efficiently, and web thinning at the tip reduces thrust and improves penetration. Machinists, maintenance techs, HVAC installers, plumbers, and electricians commonly reach for jobber-length bits for everyday hole-making tasks at the bench or in the field.

The C71023 fits standard three-jaw drill chucks and magnetic-base drill setups that accept a straight cylindrical shank. With a flute length of 3-1/2 inches and a 4xD flute-to-diameter ratio, it handles moderate-depth holes without packing chips. The right-hand cutting direction is compatible with all standard clockwise-rotating drills, both corded and cordless. This bit is sized in the 0.3500 to 0.4000 inch decimal range, making it a practical choice for clearance holes, pilot holes for anchors, and general fabrication work across the trades.

Key Features

• High speed steel construction with oxide coating for heat and wear resistance
• 118-degree standard point angle for reliable starting on common materials
• Web-thinned, tapered-web tip reduces drilling thrust and improves bite
• Spiral regular-helix flutes with 4xD ratio for efficient chip evacuation
• Straight cylindrical shank fits standard drill chucks without modification
• Meets ASME B94.11M and DIN 338 standards for consistent dimensional accuracy

Compatibility

Designed as an OEM-style general-purpose jobber-length drill bit for use in any standard three-jaw drill chuck accepting a straight cylindrical shank sized at 0.3594 inches diameter.

Installation Notes

Secure the shank fully in the chuck and verify the bit runs true before drilling. Use cutting fluid or coolant when drilling hardened metals to extend bit life, noting that this bit does not support coolant-through delivery. Run at a spindle speed appropriate for the workpiece material and bit diameter per standard machining feeds-and-speeds tables. Inspect the cutting edges for wear before each use and replace if chipping or dullness is observed.
