Cleveland C14630 7/32 in Cobalt Screw Machine Drill Bit

Product Description

The CLEVELAND C14630 is a cobalt screw machine length drill bit designed for high-performance drilling in tough materials. Built to M42 cobalt steel grade standards, it features a 135-degree split point for fast starts and reduced walking on hard surfaces. The bit measures 7/32 inch (0.2188 inches) in diameter with a 2-3/8 inch overall length and a 1-1/4 inch flute length. Its web-thinned, parallel web construction reduces thrust and improves chip evacuation. This is a heavy-duty tool used by machinists, maintenance mechanics, and metal fabricators working on production or repair applications.

The C14630 is suited for drilling alloy steel and aluminum in screw machine and short-hole drilling applications. Its screw machine length profile makes it a practical choice for use in drill presses, CNC machines, turret lathes, and hand drills where a shorter, stiffer bit is needed to maintain accuracy and reduce deflection. The straight-cylindrical shank fits standard chuck sizes matching the 0.2188-inch diameter. Two spiral flutes clear chips efficiently during through-hole and blind-hole operations.

Key Features

• M42 cobalt construction handles heat and abrasion in alloy steel and aluminum
• 135-degree split point reduces drill walking and lowers entry thrust
• Web-thinned parallel web design improves chip flow and reduces feed pressure
• Screw machine length (2-3/8 inches OAL) provides rigidity and accuracy in tight setups
• Right-hand cut, two-flute spiral configuration for standard clockwise drilling
• Meets ASME B94.11M and DIN 1897 standards for consistent dimensional tolerances

Compatibility

Designed as an OEM-style replacement or direct-use cobalt drill bit for screw machine and short-hole drilling operations in standard drill chucks accepting a 0.2188-inch straight-cylindrical shank. Compatible with alloy steel and aluminum workpieces per Series 2133 specification.

Installation Notes

Install into a properly sized chuck and tighten securely before operation. Ensure the drill press, lathe, or hand drill is powered off and locked out before changing bits. Use appropriate cutting fluid or coolant when drilling alloy steel to extend tool life, as this bit does not support through-coolant delivery. Follow applicable OSHA and shop safety standards for rotating cutting tools, including proper workpiece clamping.
