Cleveland C71253 Jobber Drill Bit 4.8mm Hss Oxide 118

Product Description

The CLEVELAND C71253 is a jobber-length twist drill bit designed for general-purpose metal drilling in light to medium shop and field applications. Built from high speed steel with an oxide coating for improved lubricity and mild corrosion resistance, it carries a 4.8 mm (0.1890 inch) diameter and an overall length of 3.386 inches. The 118-degree standard point angle suits a wide range of common metals, plastics, and wood composites. A web-thinned, tapered web configuration reduces thrust at the cutting tip and aids chip evacuation during through-hole drilling. The straight-cylindrical shank fits standard three-jaw drill chucks without adapters, and the two-flute spiral design clears chips efficiently on shorter-depth holes.

This bit is suited for general fabrication, maintenance, and service work where a consistent, reliable jobber-length drill is needed. Electricians, plumbers, HVAC techs, and general maintenance mechanics regularly use jobber-length bits like the C71253 for panel knockouts, pipe brackets, equipment mounting holes, and similar trade tasks. The 4.8 mm diameter is a common metric size used in fixture and conduit work. Conformance to ASME B94.11M and DIN 338 ensures dimensional consistency across replacement bits of the same designation.

Key Features

• High speed steel construction with oxide coating for improved wear resistance and chip flow
• 118-degree standard point angle for general-purpose drilling in metal, plastic, and wood composites
• Web-thinned, tapered web reduces cutting thrust and improves hole entry
• Two-flute regular spiral design promotes efficient chip evacuation
• Straight-cylindrical shank seats directly in standard three-jaw chucks
• Meets ASME B94.11M and DIN 338 dimensional standards for consistent sizing

Compatibility

Designed as an OEM-style jobber-length drill bit conforming to DIN 338 and ASME B94.11M standards, compatible with any standard three-jaw drill chuck accepting a 0.1890-inch straight-cylindrical shank.

Installation Notes

Secure the shank fully in the chuck and verify concentricity before drilling. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend edge life and reduce heat buildup. Always wear eye protection and secure the workpiece before operation. Dispose of worn bits in accordance with applicable shop safety practices.
