Cleveland C14250 Screw Machine Drill Bit No. 10 Cobalt

Product Description

The CLEVELAND C14250 is a screw machine length cobalt drill bit designed for high-performance drilling in demanding shop and field applications. Built from M42 cobalt high-speed steel with a parabolic flute geometry and a 135-degree split point, it delivers fast, accurate starts without a center punch. The oxide straw coating reduces friction and helps shed heat during cuts. At 2.25 inches overall length, this stub-length bit fits tight clearance setups where standard jobber bits cannot reach. The straight cylindrical shank measures 0.1935 inches in diameter, matching the No. 10 wire gauge drill size of 0.1935 inches decimal. Licensed machinists, tool-and-die techs, and maintenance professionals reach for this bit when material toughness or workspace constraints rule out longer drills.

This bit is suited for production drilling and maintenance repair operations across a wide range of materials including aluminum, brass, carbon steel, cast iron, nickel alloy, stainless steel, tool steel, and plastics. The short overall length and parabolic flute profile make it a reliable choice on drill presses, CNC machining centers, and hand-held power drills where chip evacuation and rigidity matter. The heavy-duty grade designation and M42 cobalt matrix make it appropriate for interrupted cuts and harder workpiece materials that would quickly dull standard HSS bits.

Key Features

• M42 cobalt steel construction for extended tool life in hard and abrasive materials
• 135-degree split point with web thinning for self-starting accuracy and reduced thrust
• Parabolic flute geometry promotes efficient chip evacuation, reducing heat buildup
• Oxide straw coating lowers friction and adds surface hardness
• Screw machine (stub) length of 2.25 inches overall for rigid setups in tight clearances
• Diameter tolerance held to +0.0000 to -0.0007 inches for consistent fit in close-tolerance holes

Compatibility

Designed as an OEM-style replacement or direct-use drill bit for any application requiring a No. 10 wire size (0.1935 inches) screw machine length bit with a straight cylindrical shank, conforming to ANSI specification standards.

Installation Notes

Install in a properly rated chuck that accepts a 0.1935-inch straight shank before energizing any drill press or power tool. Secure the workpiece firmly before drilling to prevent rotation and bit breakage. Follow shop safety protocols and applicable OSHA machine guarding requirements when operating drilling equipment. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
