Cleveland C11686 Jobber Drill Bit 32 Hss 135 Split Point

Product Description

The CLEVELAND C11686 is a jobber-length twist drill bit designed for precision hole-making in metalworking and general fabrication applications. Ground from high speed steel with a bright uncoated finish, this bit features a 135-degree split point that reduces walking on entry and lowers thrust requirements compared to conventional 118-degree geometry. The web-thinned design further reduces cutting resistance. At 0.1160 inches in diameter (wire size 32) with a 2.75-inch overall length, the C11686 is sized for close-tolerance work requiring consistent, repeatable hole diameters. It is installed by machinists, maintenance technicians, and trade professionals working in light manufacturing, HVAC fabrication, and mechanical assembly.

This drill bit is suited for use in aluminum and non-ferrous metals as its primary workpiece material, though its high speed steel construction handles a broad range of general-purpose drilling tasks. The straight cylindrical shank measures 0.1160 inches in diameter and 1.125 inches in length, making it compatible with standard drill chucks and quick-change systems commonly used in benchtop drill presses and hand drills. The 1.625-inch spiral flute length provides adequate chip clearance for the bit diameter and typical stack thicknesses encountered in sheet metal and structural fabrication work. The Series 2222 designation indicates a heavy-duty grade within the Cleveland line.

Key Features

• 135-degree split point reduces bit walking and decreases entry thrust
• Web-thinned tapered web lowers cutting resistance and improves chip flow
• High speed steel construction provides hardness and wear resistance for production drilling
• Bright uncoated finish suitable for use with cutting fluids on aluminum and non-ferrous materials
• Right-hand spiral flute with regular helix for consistent chip evacuation
• Meets NAS 907 Type B specification for dimensional and performance standards

Compatibility

Designed as a direct-fit replacement for any standard jobber-length drill bit in wire size 32 (0.1160 inches) with a straight cylindrical shank, compatible with drill chucks accepting shank diameters at or above 0.1160 inches.

Installation Notes

Installation requires a drill press, hand drill, or machine spindle with a properly tightened chuck rated for the shank diameter. Secure the workpiece before drilling to prevent rotation and ensure accurate hole placement. Use appropriate cutting fluid or lubricant when drilling aluminum or ferrous metals to extend bit life and improve finish quality. Inspect the cutting edges before use and replace bits showing chipping, heat discoloration, or dimensional wear outside the stated tolerance of -0.0005 to 0.0000 inches.
