Cleveland C14669 Screw Machine Drill Bit 19/64 in Cobalt

Product Description

The CLEVELAND C14669 is a cobalt screw machine length drill bit designed for high-production drilling in tough materials. Built to M42 cobalt steel grade standards, it delivers heat and wear resistance needed when cutting through alloy steels and aluminum. The bit features a 135-degree split point for fast penetration and reduced walking on entry, eliminating the need for a center punch in most setups. At 2.75 inches overall length with a straight cylindrical shank, it fits standard drill chucks and quick-change toolholders used in CNC, turret, and bench drilling applications. This is a heavy-duty bit intended for use by machinists and tool-room professionals.

The C14669 is suited for production and job-shop environments where short-length rigidity matters. The screw machine length body reduces deflection in close-tolerance work on alloy steel and aluminum workpieces. Web-thinned geometry improves chip evacuation and reduces thrust load on the spindle. The 19/64 inch diameter covers a common hole size used in fastener clearance and tapping prep operations across metal fabrication, maintenance, and repair work.

Key Features

• M42 cobalt steel construction for elevated heat resistance in hard-material drilling
• 135-degree split point reduces entry walking and lowers required thrust force
• Web-thinned, parallel web configuration improves chip flow and reduces heat buildup
• Screw machine length body provides added rigidity over jobber-length bits
• Right-hand cut with 2-flute spiral geometry for standard drilling operations
• Meets ASME B94.11M and DIN 1897 specifications for consistent dimensional accuracy

Compatibility

Designed as a screw machine length replacement drill bit for use in standard straight-shank drill chucks and toolholders compatible with 19/64 inch shank diameter tooling in bench, turret, and CNC drilling setups.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or maintenance professionals familiar with rotating cutting tools. Secure the shank fully in the chuck and verify runout before drilling. Always power down and de-energize the machine before changing bits. Follow applicable OSHA machine guarding and PPE requirements for drilling operations.
