Silver & Deming Drill

The Chicago-Latrobe 55496 is a reduced-shank drill bit designed for drilling large holes with a standard 1/2-inch chuck. It suits metalworkers and maintenance technicians who need a single bit for occasional large-diameter work in steel or iron.

1/2-inch chuck compatibility

The reduced shank allows the 1 1/2-inch cutting diameter to be used in drill presses or hand drills limited to a 1/2-inch capacity. This avoids the need for a larger chuck or a Morse taper adapter, freeing up the machine for other tooling.

1 1/2-inch capacity

The high-speed steel construction with black oxide finish handles mild steel, cast iron and similar materials at the full 1 1/2-inch diameter. The 118-degree point angle provides general-purpose cutting but is not optimised for hard alloys or deep-hole chip evacuation beyond moderate depths.

Questions about this item

How long does the 118-degree point hold its edge in continuous steel drilling?

The 118-degree high-speed steel point resists wear during extended drilling in mild steel and cast iron.

Does the bit run hot enough to burn the workpiece during a full shift?

Black-oxide finish reduces friction and heat build-up so the bit stays cooler in sustained use.

Will my half-inch chuck accept the reduced shank without an adapter?

The 1/2 reduced shank fits directly into any standard 1/2-inch drill chuck.
