Chicago-latrobe 44284 Jobber Drill Bit No 14 Hss 118 Deg

Product Description

The CHICAGO-LATROBE 44284 is a jobber-length twist drill bit in wire gauge size No. 14, with a decimal diameter of 0.1820 inches. It is made from high-speed steel with a bright uncoated finish and a standard 118-degree point angle. The two-flute spiral design with a regular helix provides efficient chip evacuation during drilling. A web-thinned, tapered web reduces thrust and improves starting accuracy. This bit is used in general-purpose drilling applications across metalworking, fabrication, and maintenance trades. At 3-3/8 inches overall length with a 2-3/16 inch flute length, it fits standard drill chucks with a straight cylindrical shank.

The 44284 is suited for drilling non-ferrous metals including aluminum, brass, copper, and similar materials. Its general-purpose grade and DIN 338 compliance make it a reliable choice for machine shop use, field maintenance, and production drilling at moderate speeds. The straight cylindrical shank accepts standard three-jaw chucks on benchtop drill presses, hand drills, and CNC drilling centers. It is sold individually with a minimum order quantity of 12 units per order.

Key Features

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard three-jaw chucks and drill press spindles accepting a 0.1820 inch straight cylindrical shank. Primary workpiece material is non-ferrous metal per manufacturer specification.

Installation Notes

Installation and use of this bit should be performed by machinists or qualified tradespeople familiar with drill press and hand drill operation. Secure the shank fully in the chuck before operation and verify the chuck key is removed before powering the machine. Match spindle speed to the workpiece material and bit diameter per standard machining feeds-and-speeds references. Inspect the cutting edges for wear or chipping before each use and replace the bit if point geometry is compromised.
