Chicago-latrobe 52450 Reduced Shank Drill Bit 25/32 in

Product Description

The CHICAGO-LATROBE 52450 is a reduced shank twist drill bit designed for portable drilling applications in metal, cast iron, and wood. It features a 25/32 inch cutting diameter with a 1/2 inch Weldon shank, allowing it to seat securely in standard half-inch chucks and side-lock holders without slipping. The bit is manufactured from high speed steel with a coated finish for added wear resistance. A 118-degree split point reduces walking at startup and lowers thrust requirements compared to a conventional point. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling operations.

The 52450 belongs to the CHICAGO-LATROBE 190F series and is suited for general-purpose portable drilling on job sites and in shop environments. The reduced shank design makes a larger diameter bit accessible through smaller chuck capacities, a practical solution when drilling alloy steel, carbon steel, cast iron, or wood with a half-inch drive tool. The 3-number-of-flats Weldon shank prevents rotation in the holder under torque loads common to larger diameter bits. Licensed electricians, pipefitters, ironworkers, and general contractors typically reach for this bit when oversized holes are needed with standard portable equipment.

Key Features

• 25/32 inch cutting diameter (0.7812 inch decimal) with a tolerance of +0.0000 to -0.0012 inches
• 1/2 inch Weldon shank with 3 flats for positive torque transfer in side-lock holders
• 118-degree split point for reduced walking and lower feed pressure at entry
• High speed steel construction with coated finish for extended service life
• Right-hand cut, regular spiral flutes for efficient chip evacuation
• General-purpose rating suitable for wood, alloy steel, carbon steel, and cast iron

Compatibility

Designed for use in portable drilling applications with 1/2 inch side-lock or Weldon-style chuck systems. Compatible workpiece materials include wood, alloy steel, carbon steel, and cast iron per manufacturer specification.

Installation Notes

Secure the Weldon shank fully into a compatible side-lock holder, engaging all three flats before tightening set screws. Ensure the drilling tool is powered off and unplugged before inserting or removing the bit. Apply cutting fluid when drilling ferrous metals to reduce heat buildup and extend bit life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point geometry is compromised.
