Cleveland C23842 1/4 in Mechanics Drill Bit Hss Split Point

Product Description

The CLEVELAND C23842 is a mechanics-length twist drill bit designed for general-purpose hole-making in metal and similar materials. Built from high-speed steel (HSS), it features a 135-degree split point that reduces walking on contact and lowers the thrust needed to start the cut. The 1/4 inch diameter with a flatted shank seats securely in standard drill chucks and prevents rotation slippage under load. At 3.5 inches overall length, the mechanics-length body gives better rigidity and control in tight spaces compared to jobber-length alternatives. This bit conforms to ASME B94.11M standards and is suited for right-hand cutting operations.

This drill bit is used in metalworking, fabrication, and maintenance trade applications where accurate, clean entry holes are required in cast iron and steel workpieces. The shorter mechanics-length body makes it practical for HVAC technicians, pipefitters, electricians, and general maintenance mechanics working in confined areas such as equipment panels, mechanical rooms, or structural framing. It is sold individually and fits into any standard keyed or keyless chuck that accepts a 1/4 inch flatted shank.

Key Features

• 135-degree split point reduces bit walking and lowers required feed pressure on entry
• High-speed steel construction withstands the heat generated during metal drilling
• Flatted shank prevents rotation slip in chuck jaws under heavy feed loads
• Mechanics length (3.5 inches OAL) provides added rigidity over jobber-length bits
• Right-hand spiral flute with 2-inch flute length clears chips efficiently during cut
• Meets ASME B94.11M standards for drill bit geometry and dimensional consistency

Compatibility

Designed for drilling cast iron and steel workpieces as a general-purpose mechanics-length drill bit compatible with standard 3/8 inch or 1/2 inch keyed and keyless drill chucks accepting a 1/4 inch flatted shank.

Installation Notes

Secure the flatted shank fully into the chuck and tighten all jaws before drilling. Use appropriate cutting fluid or lubricant when drilling steel to extend bit life and improve hole finish. Apply steady, consistent feed pressure and reduce feed rate as the bit breaks through the far side of the workpiece to avoid grabbing. Dispose of worn or chipped bits rather than attempting to use them at reduced performance, as a damaged split point increases the risk of bit breakage.
