Single 13/16 in Drill Bit
The Chicago-Latrobe 55452 is a Silver & Deming drill bit with a 13/16 in cutting diameter and a 1/2 in reduced shank. It is made from high speed steel with a black oxide finish. The 118 degree point angle suits general purpose drilling in metal, wood and plastic. It is sold individually for specific hole sizing.
For Targeted Hole Sizing
This bit suits machinists and maintenance technicians who need a single large-diameter hole with a standard 1/2 in chuck capacity. It is not for buyers who need a set covering multiple diameters, users requiring a different point angle for self-centering, or shops needing cobalt or carbide material grades.
13/16 in Cutting Diameter
The 13/16 in drill bit size is the specification that decides fit. Verify that your application requires this exact diameter and that your drill chuck accepts a 1/2 in reduced shank before purchasing.

Questions about this item
What chuck size do I need to run the 1/2 inch reduced shank on this 13/16 in drill bit?
Your drill chuck must accept at least a 1/2 inch shank; the 13/16 in cutting diameter is larger, so the chuck only needs to grip the reduced shank portion.
Will the 118 degree point angle work well in the mild steel I usually drill with older high-speed steel bits?
Yes, the 118 degree point is a general-purpose angle that performs similarly to traditional high-speed steel bits in mild steel, so your existing technique transfers directly.
How can I confirm the black oxide finish is providing the expected wear resistance after I start drilling?
The cutting lips should stay sharp longer and show less discoloration than uncoated high-speed steel when drilling comparable holes in the same material.
