Cleveland C14572 Cobalt Drill Bit 1/8 Inch 135 Point

Product Description

The CLEVELAND C14572 is a screw machine length drill bit designed for high-production drilling in tough materials. Built from M42 cobalt high-speed steel, it handles alloy steels and aluminum where standard HSS bits fail. The 135-degree split point reduces walking and lowers the thrust needed to start a hole, so no center punch is required on most setups. At 1-7/8 inches overall length, it fits short-reach applications and quick-change chucks on drill presses, CNC turret lathes, and screw machines. The straight-cylindrical shank measures 0.125 inches in diameter and seats securely in standard chucks. This bit is a go-to for machinists and tool-and-die techs running repetitive drilling cycles.

The C14572 is suited for production environments where cycle time and tool life matter. Its screw machine length keeps the bit rigid in short-reach fixtures, reducing deflection on close-tolerance holes. Primary workpiece materials include alloy steel and aluminum, making it useful in job shops, aerospace component work, and general metalworking. The web-thinned parallel web design improves chip evacuation and reduces heat buildup during continuous use. This bit ships individually but requires a minimum order quantity of 10 units, which aligns with typical crib-stocking and production consumption rates.

Key Features

• M42 cobalt construction for heat resistance and extended tool life in hard metals
• 135-degree split point for self-centering starts and reduced thrust requirements
• Web-thinned parallel web design improves chip flow and reduces heat buildup
• Screw machine length (1-7/8 inches OAL) provides rigidity in short-reach drilling setups
• Right-hand cut with 2-flute regular spiral geometry for consistent chip evacuation
• Diameter tolerance of +0.0000 to -0.0005 inches for close-tolerance hole sizing

Compatibility

Designed for use in standard drill presses, CNC lathes, turret machines, and hand-held power drills with chucks accepting a 0.125-inch straight-cylindrical shank. Suitable for drilling alloy steel and aluminum workpieces per Cleveland Series 2133 specifications.

Installation Notes

A licensed machinist or qualified metalworking professional should verify chuck compatibility and proper shank seating before use. Secure the workpiece firmly before drilling and confirm the machine is at a full stop before changing or inspecting the bit. Follow applicable OSHA machine guarding requirements and the manufacturer's recommended speeds and feeds for the workpiece material. Do not use this bit on masonry, wood, or plastic applications for which it is not rated.
