Reduced-Shank Drill Bit
The Chicago-Latrobe 55459 is a Silver & Deming drill bit built for machinists and maintenance technicians who need to bore large-diameter holes with a standard 1/2 inch chuck. Its 118-degree point angle suits general-purpose drilling in ferrous and non-ferrous metals.
1/2 Inch Shank Compatibility
The reduced shank lets the 59/64 inch cutting diameter run in any drill press or handheld drill that accepts a 1/2 inch shank, freeing the user from sourcing a larger-capacity chuck or specialised tool holder. Black oxide finish adds lubricity and corrosion resistance during extended use.
59/64 Inch Cutting Capacity
This bit cleanly produces holes just under one inch in diameter, covering common bolt-clearance and pipe-tap sizes in steel, cast iron and aluminium. It is not suited for holes larger than 59/64 inch or for precision work requiring tighter tolerances than a standard 118-degree point provides.

Questions about this item
How deep can the 59/64 in drill bit go before the 1/2 reduced shank limits the hole depth?
The 1/2 reduced shank on the 59/64 in bit lets you drill deeper holes in thick material than a straight-shank bit of the same diameter would allow.
Does the 118 degree point angle on the high-speed steel bit generate noticeable heat during all-day drilling?
The 118 degree point angle on the high-speed steel bit is designed for general-purpose cutting and helps manage heat build-up during extended drilling sessions.
Will the 59/64 in silver and deming drill fit my 1/2 in drill chuck without an adapter?
Yes, the 1/2 reduced shank on the 59/64 in bit is made to fit directly into a standard 1/2 in drill chuck.
