Cleveland C04470 Screw Machine Drill Bit 3/16 in Hss

Product Description

The CLEVELAND C04470 is a screw machine length drill bit designed for high-speed steel cutting in metal fabrication, maintenance, and general machining applications. Built to ASME B94.11M standards, this bit measures 3/16 inches (0.1875 inches) in diameter with an overall length of 2-3/16 inches, making it a compact stub-length tool suited for close-quarter drilling operations. The 118-degree standard point geometry provides reliable entry on flat and curved surfaces. Web thinning reduces thrust requirements and helps the point self-center. This bit is sold individually and is intended for use by machinists, maintenance technicians, and trade professionals working with drill presses, lathes, or hand-held power tools.

The C04470 is a general-purpose bit from the Cleveland Series 2120, optimized for drilling into alloy steel and aluminum. Its short screw machine length makes it well suited for applications where a standard jobber-length bit would flex, chatter, or lack rigidity — such as drilling on manual mills, drill presses, or CNC turret setups where spindle clearance is limited. The straight-cylindrical shank is compatible with standard drill chucks across a wide range of machine types.

Key Features

• 3/16 inches (0.1875 inches) diameter with a diameter tolerance of +0.0000 to -0.0007 inches for consistent hole sizing
• 118-degree standard point angle with web thinning for reduced thrust and improved self-centering
• High-speed steel construction with bright/uncoated finish for general-purpose ferrous and non-ferrous cutting
• Screw machine (short) length of 2-3/16 inches OAL provides added rigidity over jobber-length bits
• Right-hand spiral flutes with regular helix for efficient chip evacuation
• Meets ASME B94.11M dimensional standards

Compatibility

Designed as a general-purpose screw machine length drill bit suitable for use in standard drill chucks and collet holders accepting a 0.1875-inch straight-cylindrical shank. Primary workpiece materials include alloy steel and aluminum.

Installation Notes

Installation and use should be performed by a qualified machinist or trained technician. Secure the shank fully in the chuck and verify runout before drilling. Always power down and de-energize the machine before changing bits. Use appropriate cutting fluid or coolant when drilling hardened alloys to extend tool life, noting that this bit does not support coolant-through delivery.
