Chicago-latrobe 44213 Jobber Drill Bit 13/64 in Hss

Product Description

The CHICAGO-LATROBE 44213 is a jobber-length twist drill bit designed for general-purpose drilling in metal fabrication, maintenance, and light industrial applications. Built from high speed steel with a bright uncoated finish, this bit features a 118-degree standard point angle and a right-hand spiral flute for efficient chip evacuation. The straight cylindrical shank measures 13/64 inch in diameter, matching the bit diameter for straightforward chuck mounting. At 3-5/8 inches overall length with a 2-7/16-inch flute length, it fits standard jobber-length drill presses, hand drills, and CNC drilling equipment. The tapered web with web thinning reduces thrust and improves centering on entry.

This bit is suited for drilling non-ferrous metals including aluminum, brass, copper, and similar materials in residential and commercial trade applications. Electricians, plumbers, HVAC technicians, and general contractors use jobber-length bits for conduit knockout, pipe fitting clearance holes, structural framing, and fixture mounting. The Series 150D is a general-purpose line built to DIN 338 standards, making it a common shop and field staple across multiple trades. Sold individually; minimum order quantity is 12 units per order.

Installation Notes
