Chicago-latrobe 44092 No. 22 Hss Jobber Drill Bit

Product Description

The CHICAGO-LATROBE 44092 is a jobber-length twist drill bit in wire gauge size No. 22, with a decimal diameter of 0.1570 inches. It is manufactured from high speed steel with an oxide coating to reduce friction and extend tool life in general-purpose drilling applications. The bit features a 118-degree standard point angle, a regular spiral flute, and a straight-cylindrical shank. Overall length is 3-1/8 inches with a 2-inch flute length. It is suited for use by machinists, maintenance technicians, and metalworking trades who need a reliable, shop-grade jobber bit for repetitive hole-making tasks.

This bit is designed for drilling cast iron and steel in general-purpose production and maintenance environments. The web-thinned, tapered web construction reduces thrust requirements at the cutting tip, making it well-suited for hand-feed drilling operations on drill presses or portable electric drills. The Series 150 designation places it within a recognized line of standard jobber-length bits conforming to DIN 338 dimensional standards. It is sold individually but is subject to a minimum order quantity of 12 pieces per order.
