Cleveland C23839 Mechanics Drill Bit 13/64 in Hss Split Point

Product Description

The CLEVELAND C23839 is a mechanics-length drill bit designed for general-purpose drilling in ferrous metals, cast iron, and steel. Built from high-speed steel, this bit features a 135-degree split point that reduces walking and allows drilling to begin without a center punch. The flatted shank provides positive engagement in three-jaw and keyed chucks, preventing slippage under torque. At 3.13 inches overall length, the mechanics-length body fits tight spaces where jobber-length bits would be too long. Right-hand spiral flutes evacuate chips efficiently, making this bit well-suited for production and maintenance drilling alike.

This bit is sized at 13/64 inch (0.2031 inch decimal equivalent) and is appropriate for through-hole work, bolt clearance drilling, and pilot operations in steel fabrication, HVAC equipment assembly, and general mechanical maintenance. The 135-degree split point geometry is particularly effective in harder steels and cast iron where a conventional 118-degree bit would require more feed pressure and is more prone to skidding. Trade professionals in mechanical, HVAC, plumbing, and electrical fields use mechanics-length bits in confined cabinet and panel areas where longer bits cannot operate.

Key Features

• 135-degree split point starts on contact without center punching
• High-speed steel construction handles cast iron and steel workpieces
• Flatted shank prevents slippage in standard chuck jaws
• Mechanics length at 3.13 inches overall for use in restricted spaces
• 1.94-inch flute length with right-hand spiral for efficient chip evacuation
• Conforms to ASME B94.11M dimensional standard

Compatibility

Designed as a general-purpose mechanics-length drill bit for use in standard keyed or keyless chucks accepting a 0.2031-inch flatted shank. Rated for primary workpiece materials including steel and cast iron (material codes P and K).

Installation Notes

Secure the flatted shank fully into the chuck and tighten all jaws before drilling. Use appropriate cutting fluid or lubricant when drilling harder steels to extend bit life and maintain point geometry. Allow the split point to establish the hole before increasing feed pressure. Inspect the cutting edges for wear after extended use in abrasive or hardened materials, and replace the bit if chipping or dulling is observed.
