Cleveland C71292 Jobber Length Drill Bit 8.7 Mm Hss

Product Description

The CLEVELAND C71292 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high speed steel with an oxide coating, it measures 8.7 mm (0.3425 inches) in diameter and carries an overall length of 4.921 inches. The 118-degree standard point angle and web-thinned tip reduce entry force and improve centering on flat and curved surfaces. Two spiral flutes with a regular helix evacuate chips efficiently during through-hole drilling. This bit is a standard item for HVAC, plumbing, and electrical tradespeople who need a reliable jobber-length bit for sheet metal, brackets, and structural steel work.

The C71292 fits hand-held drills, drill presses, and machine tool chucks with straight-cylindrical shanks. At 0.3425 inches in shank diameter, it is compatible with standard 3/8-inch and 1/2-inch keyed or keyless chucks. The flute length of 3.189 inches provides adequate chip clearance for moderate-depth holes. This bit is well suited for repetitive production drilling and service-call fieldwork where consistent, clean holes are required in ferrous and non-ferrous materials.

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard 3/8-inch and 1/2-inch straight-chuck hand drills and drill presses; conforms to DIN 338 and ASME B94.11M specifications for interchangeability with other bits in that standard.

Installation Notes

Install in a properly sized drill chuck and tighten securely before use. Secure the workpiece with a vise or clamps to prevent rotation during drilling. Apply cutting fluid when drilling hard metals to extend bit life and improve hole quality. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
