Chicago-latrobe 52456 Reduced Shank Drill Bit 7/8 in

Product Description

The CHICAGO-LATROBE 52456 is a reduced shank twist drill bit engineered for portable drilling applications in metal, wood, and cast iron. It features a 7/8 inch cutting diameter paired with a 1/2 inch Weldon shank, allowing it to fit standard 1/2 inch drill chucks while delivering a larger bore diameter. The 118-degree split point promotes accurate starting and reduces walking on entry. Built from high speed steel with a coated finish, the bit handles general-purpose drilling across a broad range of workpiece materials. Tradespeople and maintenance technicians reach for this bit when an oversize hole is needed without switching to a larger chuck capacity tool.

The 52456 is suited for portable drilling setups in residential, commercial, and light industrial environments. Its reduced shank design makes it especially practical on job sites where a 1/2 inch chuck drill is the available tool but a hole larger than 1/2 inch is required. Primary workpiece material is wood, with secondary compatibility covering alloy steel, carbon steel, and cast iron. The right-hand spiral flute configuration clears chips efficiently during through-hole and blind-hole drilling.

Key Features

• 7/8 inch cutting diameter with 1/2 inch Weldon shank for use in standard 1/2 inch chucks
• 118-degree split point for accurate, low-thrust starting on metal and wood
• High speed steel construction for durability across general-purpose applications
• Coated finish to extend cutting life and reduce friction during drilling
• 3-flute Weldon shank with 3 flats prevents slipping in the chuck under load
• Right-hand spiral flutes promote efficient chip evacuation

Compatibility

Designed for use in portable drilling applications with 1/2 inch chuck capacity equipment. Compatible with wood, alloy steel, carbon steel, and cast iron workpieces. Part of the CHICAGO-LATROBE 190F series of reduced shank drill bits.

Installation Notes

Installation is performed by machinists, maintenance technicians, or skilled tradespeople using a 1/2 inch keyed or keyless chuck drill. Secure the Weldon shank firmly in the chuck, engaging all three flats to prevent rotation under torque. Ensure the workpiece is properly clamped or fixtured before drilling. Power down the tool completely before changing or inspecting the bit.
