Cleveland C71245 Jobber Length Drill Bit 4 Mm Hss

Product Description

The CLEVELAND C71245 is a jobber-length twist drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel (HSS) with an oxide coating, it measures 4 mm (0.1575 inches) in diameter and 2.953 inches in overall length. The 118-degree standard point angle and web-thinned tip reduce entry force and help keep the bit on target at the start of each hole. Two spiral flutes with a regular helix evacuate chips efficiently during drilling. This bit is installed by machinists, maintenance technicians, electricians, and plumbers who need a reliable general-purpose drill for metal, wood, and plastic applications.

The C71245 is suited for bench drill presses, hand drills, and drill drivers in both shop and field settings. Its straight-cylindrical shank fits standard three-jaw drill chucks across portable and stationary drilling equipment. The 4xD flute-to-diameter ratio and 1.693-inch flute length provide adequate chip clearance for typical through-hole and blind-hole work encountered in residential and light commercial trade applications. It conforms to ASME B94.11M and DIN 338 standards, making it a recognized interchangeable form factor across tools and tooling systems.

Installation Notes

Install and remove drill bits only with the drill unplugged or the power source locked out and tagged per applicable safety procedures. Secure the workpiece firmly before drilling to prevent rotation or movement. Inspect the cutting edges and flutes before each use and replace bits that show chipping, excessive wear, or discoloration from overheating. Follow applicable shop safety standards and wear appropriate eye protection during all drilling operations.
