Cleveland C14689 11/32 in Cobalt Screw Machine Drill Bit

Product Description

The CLEVELAND C14689 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding shop and field applications. Built from M42 cobalt high-speed steel, this bit handles tough materials where standard HSS tooling falls short. It measures 11/32 inch (0.3438 inches) in diameter with a 3-inch overall length and features a 135-degree split point that reduces walking and minimizes the need for a center punch. The web-thinned, parallel-web construction supports consistent chip evacuation and reduces thrust load during entry.

This bit is suited for drilling alloy steel and aluminum in production and maintenance environments. The screw machine length profile — shorter than jobber length — provides added rigidity and is a standard choice for drill press, CNC turret, and hand-drill work where stub-length stability is preferred. The straight cylindrical shank seats directly in standard drill chucks without modification. Licensed tradespeople and machinists working in fabrication, mechanical contracting, and industrial maintenance will find this bit sized and built for repetitive, close-tolerance work.

Key Features

• M42 cobalt construction for extended tool life in alloy steel and aluminum
• 135-degree split point reduces drill walk and lowers entry thrust
• Web-thinned parallel web promotes chip clearance and reduces heat buildup
• Screw machine (stub) length adds rigidity compared to jobber-length bits
• Right-hand cut with 2-flute spiral configuration for standard drilling operations
• Meets ASME B94.11M and DIN 1897 standards; ANSI and DIN designation

Compatibility

Designed as a replacement or direct-use screw machine length drill bit for applications requiring an 11/32-inch diameter hole in alloy steel or aluminum. Compatible with any standard drill chuck accepting a 0.3438-inch straight cylindrical shank. Series 2133 per Cleveland catalog.

Installation Notes

Install in a properly sized drill chuck and verify the shank is fully seated and securely tightened before operation. Use appropriate cutting fluid for alloy steel to manage heat and extend tool life. Inspect the cutting edges and split point before each use — cobalt bits can chip if run at incorrect speeds or used on hardened materials beyond their rated range. Follow shop safety procedures and applicable OSHA standards when operating drilling equipment.
