Chicago-latrobe 44082 Jobber Drill Bit Wire 12 Hss

Product Description

The CHICAGO-LATROBE 44082 is a jobber length drill bit in wire size number 12, with a decimal diameter of 0.1890 inches. It is manufactured from high speed steel with an oxide coating that helps reduce friction and extend service life under repeated use. The bit features a standard 118-degree split point, a 2-flute spiral flute design with a regular spiral type, and a straight-cylindrical shank for use in standard drill chucks. At 3.5 inches overall length with a 2.3125-inch flute length, this is a general purpose jobber bit suited for production drilling, maintenance, and fabrication work. It conforms to DIN 338 standards and carries a web-thinned, tapered web configuration for improved chip evacuation.

This bit is designed for drilling cast iron and steel in general purpose applications. Typical install scenarios include production shops, HVAC fabrication, plumbing rough-in, electrical panel work, and field service drilling where a standard jobber length bit is required. The oxide finish makes it a practical choice for dry cutting in ferrous metals where cutting fluid is not available. It ships as a single piece per package unit with a minimum order quantity of 12 units.
