Chicago-latrobe 52480 Reduced Shank Drill Bit 1-1/4 in

Product Description

The CHICAGO-LATROBE 52480 is a reduced shank drill bit designed for portable drilling applications across wood, alloy steel, carbon steel, and cast iron workpieces. Built from high speed steel with a coated finish, it features a 1-1/4 inch drill diameter and a 1/2 inch Weldon shank, making it compatible with standard 1/2 inch chucks while boring larger-diameter holes. The 118-degree split point promotes clean entry and reduces walking on hard surfaces. With a 6 inch overall length and a 3-1/8 inch flute length, the bit provides adequate chip clearance for general-purpose production and field drilling work. It is sold individually.

This bit is suited for general-purpose drilling in residential and light commercial construction, fabrication shops, and maintenance environments. The Weldon shank with three flats prevents slipping under torque, making it a reliable choice for portable drill setups and drill press applications where oversized holes are required in steel plate, structural members, or wood framing. The right-hand spiral flute design handles a wide range of workpiece materials without special setup.

Installation Notes

Installation and use should be performed by qualified machinists, fabricators, or tradespeople familiar with portable and stationary drilling equipment. Secure the Weldon shank firmly in a chuck or collet, ensuring all flats are properly engaged before operation. Always clamp the workpiece securely and wear appropriate eye protection. Inspect the cutting edges before each use and discontinue use if the bit shows signs of excessive wear or damage.
