Chicago-Latrobe 55450 25/32 in 118 Degree Drill Bit 1/2 Reduced Shank

Chicago-Latrobe 55450 Drill Bit

The Chicago-Latrobe 55450 is a silver and deming drill bit manufactured from high speed steel with a black oxide finish. It features a 118 degree point angle suited for general purpose drilling. The 1/2 inch reduced shank allows use in chucks that cannot accommodate larger diameters. This accessory targets machinists and maintenance technicians needing a specific large diameter hole size.

Reduced Shank Fits Standard Chucks

The 1/2 inch reduced shank limits the maximum chuck capacity required to hold the bit securely. Users must ensure their drill press or hand drill accepts a 1/2 inch shank diameter. The black oxide finish provides some corrosion resistance and helps retain cutting fluid during operation. The 118 degree point angle is a standard geometry for drilling mild steel and cast iron.

25/32 Inch Diameter Determines Fit

The drill bit size is 25/32 inch, a specific fractional dimension that dictates the final hole diameter. This measurement is the primary specification for verifying compatibility with bolt, tap or reamer requirements. No other diameter is produced by this model number. Select this bit only when the drawing or specification calls for a 25/32 inch hole.
