Chicago-latrobe 52462 Reduced Shank Drill Bit 31/32 in

Product Description

The CHICAGO-LATROBE 52462 is a reduced shank twist drill bit designed for general-purpose portable drilling in wood, alloy steel, carbon steel, and cast iron. The bit measures 31/32 inches in diameter with a 1/2-inch Weldon shank, allowing it to seat securely in standard 1/2-inch chucks where full-shank bits of this diameter would not fit. Built from high speed steel with a coated finish, it features a 118-degree split point for positive engagement and reduced walking on entry. Overall length is 6 inches with a 3-1/8-inch flute length. This bit is a Series 190F tool intended for use by machinists, maintenance technicians, and general trade professionals.

The 52462 is suited for portable drilling applications across a range of workpiece materials including wood, alloy steel, carbon steel, and cast iron. The Weldon shank with three flats resists rotation in the chuck under heavy torque loads, making it a practical choice for hand-held drilling operations on the job site or in a shop environment. The right-hand spiral flute geometry promotes consistent chip evacuation during through-hole and blind-hole drilling.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or tradesperson familiar with portable drilling equipment. Ensure the drill or drill press is powered off and the chuck is fully disengaged before inserting or removing the bit. Seat the Weldon shank fully into the chuck and tighten all set screws against the flats to prevent slippage under load. Always wear appropriate eye protection and follow applicable workplace safety codes when operating rotary cutting tools.
