Cleveland C23849 Mechanics Drill Bit 23/64 in Hss Split Point

Product Description

The CLEVELAND C23849 is a mechanics-length, high-speed steel drill bit designed for general-purpose drilling in metal fabrication and maintenance applications. Built to ASME B94.11M standards, it features a 135-degree split point that reduces walking on contact and allows drilling without a center punch on most surfaces. The flatted shank provides a positive grip in standard drill chucks, preventing slippage under torque. At 0.3594 inches (23/64 inch) in diameter with a right-hand spiral flute, this bit is suited for licensed tradespeople and shop mechanics working with steel and cast iron substrates on a daily basis.

This bit belongs to the CLEVELAND 1875R Series and is configured for mechanics-length drilling, meaning the shorter overall length provides increased rigidity compared to jobber-length bits. That rigidity reduces deflection in tight-access drilling scenarios common in HVAC equipment frames, electrical panel knockouts, and plumbing support bracketing. The right-hand cut and spiral flute geometry promote efficient chip evacuation when drilling ferrous materials. Primary workpiece materials listed by the manufacturer are cast iron and steel, making this bit applicable across a wide range of trade service environments.

Key Features

• 135-degree split point reduces bit walking and eliminates the need for a center punch on most metal surfaces
• High-speed steel (HSS) construction provides hardness and heat resistance for continuous drilling in steel and cast iron
• Flatted shank prevents rotation in chuck jaws under heavy drilling torque
• Mechanics-length body (4.19 inches overall) delivers increased rigidity and accuracy in confined spaces
• Right-hand spiral flute promotes consistent chip evacuation during ferrous drilling
• Meets ASME B94.11M dimensional standards for drill bit geometry and tolerances

Compatibility

Designed as a general-purpose mechanics-length drill bit compatible with standard 3-jaw drill chucks that accept a 0.3594-inch flatted shank. Intended for use on cast iron and steel workpieces as specified by the manufacturer.

Installation Notes

This bit is installed and operated by machinists, maintenance technicians, and licensed trade professionals using standard corded or cordless drill equipment. Secure the flatted shank firmly in the chuck before operation and verify chuck key removal prior to starting the drill. Use appropriate cutting fluid or lubricant when drilling steel or cast iron to extend bit life and reduce heat buildup. Wear eye protection and secure the workpiece before drilling.
