Chicago-Latrobe 55473 118° Reduced Shank Drill
The Chicago-Latrobe 55473 is a Silver & Deming drill bit with a 118-degree point angle and a 1/2 reduced shank. It is made from high-speed steel with a black oxide finish for durability. This bit suits machinists and fabricators drilling large-diameter holes in metal using a standard drill chuck.
For large-hole drilling in metal with a 1/2 chuck
This bit suits users who need a 1 9/64 inch high-speed steel drill with a reduced shank to fit a 1/2 capacity chuck. It is not for buyers who require a full-size shank for larger chucks. It is not for buyers who need a different drill point angle for specialised materials. It is not for buyers who need a set of multiple bit sizes.
118-degree point angle and 1/2 reduced shank
The 118-degree point angle provides a standard cutting geometry for general-purpose metal drilling. The 1/2 reduced shank allows this large-diameter bit to be used in drill presses and hand drills with a standard 1/2 chuck. These two specifications determine if the bit matches the machine and the material.

Questions about this item
How do I install the 1/2 reduced shank on my drill press?
Insert the 1/2 reduced shank fully into the chuck and tighten securely; the step people get wrong is not seating it completely, which causes runout.
What maintenance will the black oxide finish need later?
Wipe chips off after each use and apply light oil to prevent surface rust on the high speed steel body.
At what point angle does the 118 degree tip start to wander in deep holes?
The 118 degree point angle can walk on curved surfaces; start with a centre punch mark to keep the bit on target.
