Chicago-latrobe 52434 Reduced Shank Drill Bit 17/32 in

Product Description

The CHICAGO-LATROBE 52434 is a reduced shank twist drill bit designed for portable drilling applications in metal, cast iron, and wood. The bit measures 17/32 inch (0.5312 inch) in diameter with a 1/2 inch Weldon shank, a 118-degree split point, and a 6 inch overall length. It is manufactured from high speed steel with a coated finish for general-purpose durability. Licensed tradespeople and experienced DIYers use this bit when a full-size shank chuck is not available or when a Weldon flat-drive setup is preferred to prevent slippage under load.

This bit is suited for portable drilling in shops, fabrication environments, and field service work. The 17/32 inch diameter is commonly used when drilling pilot holes, clearance holes for fasteners, or rough bores in alloy steel, carbon steel, cast iron, and wood. The Weldon shank with three flats provides positive drive and prevents rotation in compatible chucks and holders. The Series 190F designation places this bit in a standard production line intended for general-purpose metal and wood drilling tasks.

Installation Notes

This bit is installed by machinists, fabricators, and maintenance trades using portable drills or drill presses fitted with a Weldon-style holder. Secure the Weldon shank fully in the holder and tighten all set screws against the flats before drilling. Wear appropriate eye and hand protection. Use cutting fluid when drilling ferrous metals to extend bit life and manage heat buildup.
