Chicago-Latrobe 55467 Drill Bit
The Chicago-Latrobe 55467 is a Silver & Deming drill bit designed for drilling large-diameter holes in metal using a standard 1/2 inch chuck. It suits maintenance technicians and fabricators who need a single bit for occasional oversize holes.
118 Degree Point Angle Constraints
The 118 degree point angle provides reliable centring in steel and cast iron but can wander on very hard or abrasive alloys without a pilot hole. The reduced shank limits torque transmission, so the bit is unsuitable for continuous heavy-duty production drilling.
High Speed Steel with Black Oxide Finish
Machined from high speed steel, the bit resists heat buildup during intermittent cuts and the black oxide finish helps retain cutting fluid at the point. The 1/2 reduced shank fits any three-jaw chuck, allowing quick changes on drill presses or portable drills without special tooling.

Questions about this item
Should I pick the 1 3/64 inch size or another capacity for this drill bit?
The 55467 model is offered in a single 1 3/64 inch diameter, so there is no alternative capacity to select.
How does the 118 degree point angle perform when the bit is in a real machine?
The 118 degree point angle provides a standard cutting geometry suited for general-purpose drilling in metal and wood on a drill press or hand drill.
What does the 1/2 reduced shank mean for chuck compatibility in practice?
The 1/2 reduced shank fits any chuck that accepts a half-inch shank, allowing the larger 1 3/64 inch bit to be used on smaller-capacity drills.
