Cleveland C14550 3/32 Inch Cobalt Screw Machine Drill Bit

Product Description

The CLEVELAND C14550 is a cobalt screw machine length drill bit designed for high-performance drilling in demanding shop and field applications. It measures 3/32 inch (0.0938 inch) in diameter with an overall length of 1-3/4 inches and a flute length of 3/4 inch. The 135-degree split point reduces walking on entry and lowers thrust requirements. Manufactured from M42 cobalt high-speed steel, this bit handles elevated heat better than standard HSS tooling, making it well suited for interrupted cuts and harder workpiece materials. It is a heavy-duty grade tool built to ASME B94.11M and DIN 1897 standards.

The C14550 is used in production drilling environments where a short, rigid bit is needed to minimize deflection in close-tolerance work. Typical applications include drilling alloy steels, aluminum, and other metals where tool longevity under heat and pressure is a priority. The screw machine (stub) length geometry suits drill presses, CNC machining centers, hand-held drill motors, and turret setups where extended reach is not required. The right-hand spiral flutes clear chips efficiently in both through-hole and blind-hole operations.

Key Features

• M42 cobalt construction withstands high cutting temperatures in alloy steel and aluminum
• 135-degree split point reduces entry walking and lowers axial thrust
• Screw machine (stub) length at 1-3/4 inches overall for maximum rigidity and minimal deflection
• Web-thinned parallel web design improves chip evacuation and reduces cutting resistance
• Straight-cylindrical shank (0.0938 inch diameter) fits standard drill chucks without adapters
• Right-hand cut with regular spiral and 2-flute configuration for balanced chip flow
• Diameter tolerance held to +0.0000 / -0.0005 inch for consistent hole sizing

Compatibility

Designed for use with standard drill chucks accepting a 0.0938-inch straight-cylindrical shank. Primary workpiece materials listed by the manufacturer include alloy steel and aluminum. Series 2133 screw machine length configuration.

Installation Notes

Installation and use of this drill bit should be performed by machinists or qualified trade professionals following applicable shop safety procedures. Secure the workpiece firmly and verify chuck runout before drilling to protect the small-diameter bit from lateral loading. Allow the bit to reach full speed before contact with the workpiece, and apply cutting fluid appropriate for the workpiece material to extend tool life. Inspect the cutting edges regularly; cobalt bits can be resharpened but should be discarded when chipping or excessive wear is observed.
