Cleveland C23853 27/64 in Mechanics Drill Bit Hss Split Point

Product Description

The CLEVELAND C23853 is a mechanics-length, high-speed steel drill bit designed for general-purpose hole drilling in metalworking applications. It features a 27/64 inch (0.4219 inch decimal) diameter with a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on hard surfaces. The flatted shank provides positive engagement in chuck jaws to prevent slipping under load. Right-hand spiral flutes evacuate chips efficiently during cutting. Licensed machinists, maintenance mechanics, HVAC technicians, and plumbers rely on this bit for drilling through cast iron, steel, and similar ferrous materials.

The C23853 is suited for metalworking tasks in both shop and field settings. Its mechanics-length designation means a shorter overall length of 4.44 inches compared to jobber-length bits, giving the user better rigidity and control in tight spaces or on drill presses. Primary workpiece materials include cast iron and steel, making it appropriate for fabrication, repair, and installation work where accurate, clean holes in ferrous material are required.

Key Features

• 135-degree split point self-centers and reduces walking on hard materials
• High-speed steel construction for durability in ferrous metal cutting
• Flatted shank prevents rotation in chuck for consistent torque transfer
• Mechanics length provides added rigidity over standard jobber bits
• Right-hand spiral flutes for efficient chip evacuation
• Meets ASME B94.11M dimensional standards

Compatibility

Designed as an OEM-style replacement or direct-use mechanics drill bit compatible with standard 3-jaw chucks and drill presses accepting a 0.4219 inch flatted shank. Intended for general-purpose drilling in cast iron and steel workpieces per Series 1875R specifications.

Installation Notes

Installation should be performed by a qualified machinist, maintenance mechanic, or trade professional familiar with rotary cutting tools. Secure the flatted shank firmly in the chuck before operation and confirm the bit runs true before drilling. Always wear appropriate eye protection and follow shop safety procedures when drilling ferrous metals. Do not exceed the drill press or hand drill rated speed for the material and bit diameter in use.
