Cleveland C71072 Jobber Length Drill Bit Letter B Hss

Product Description

The CLEVELAND C71072 is a jobber-length drill bit sized to Letter B (0.2380 inches) and manufactured from high speed steel with an oxide coating for added surface protection. Part of the 2001G series, this bit features a 118-degree standard point angle, a web-thinned and tapered web configuration, and a regular spiral flute designed for efficient chip evacuation. It is a general-purpose tool suited for a wide range of drilling applications in metalworking, mechanical, and trade shop environments. The straight-cylindrical shank measures 0.2380 inches in diameter and provides secure chuck engagement across standard drill chucks.

This bit is intended for general-purpose drilling in shop and field conditions where a Letter B diameter hole is required. With a 2.75-inch flute length and 4-inch overall length, it fits standard drill chucks used in hand drills, drill presses, and benchtop equipment. Right-hand cut geometry and a regular spiral make it appropriate for ferrous and non-ferrous materials. Licensed tradespeople working in HVAC, plumbing, electrical, and general mechanical service will find this bit a common fit for conduit, bracket, and panel drilling tasks.
