Cleveland C14554 Cobalt Screw Machine Drill Bit Size 40

Product Description

The CLEVELAND C14554 is a screw machine length cobalt drill bit designed for high-production drilling in demanding materials. Built to wire gauge size 40, it measures 0.0980 inches in diameter with a 1-13/16 inch overall length and a 13/16 inch flute length. The 135-degree split point reduces walking and cutting pressure on entry, making it well suited for hard alloys and aluminum. M42 cobalt construction provides heat and wear resistance beyond standard high-speed steel, extending tool life in repetitive or high-feed applications. The straight cylindrical shank fits standard drill chucks and collet holders without modification.

This bit is used in screw machine operations, CNC drilling, and manual drill press work where a compact flute length improves rigidity and reduces deflection in short-depth holes. Typical applications include production shops drilling alloy steel, aluminum, and similar materials where consistent hole diameter and tool longevity are priorities. The right-hand spiral and web-thinned geometry support efficient chip evacuation in both ferrous and non-ferrous workpieces.

Key Features

• M42 cobalt construction for heat resistance and extended tool life in hard materials
• 135-degree split point reduces walking and lowers thrust force on entry
• Web-thinned parallel web geometry improves chip flow and reduces cutting load
• Screw machine length body increases rigidity and minimizes deflection in short-hole drilling
• Straight cylindrical shank fits standard chucks and collet tooling
• Meets ASME B94.11M and DIN 1897 specifications for dimensional consistency

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for standard drill chucks and collet holders accepting a 0.0980 inch straight cylindrical shank across manual drill presses, benchtop drilling machines, and CNC drilling setups.

Installation Notes

Licensed machinists and tool-and-die professionals typically install and operate screw machine drill bits in production drilling equipment. Ensure the spindle is fully stopped and the chuck or collet is de-energized before mounting or removing the bit. Inspect the shank and chuck jaws for burrs or debris before seating to maintain concentricity. Follow shop safety standards and applicable machine guarding requirements during all drilling operations.
