Taper Shank Drill 55/64 in #3MT
The Chicago-Latrobe 53155 is a high-speed steel taper shank drill bit sized at 55/64 in. It features a conventional 118-degree point and a black oxide finish for corrosion resistance. This cutting tool is designed for general-purpose drilling in metal using machines equipped with a #3 Morse taper spindle.
Straightforward machine installation
Insert the taper shank directly into a matching #3 Morse taper socket or sleeve until it seats firmly; the taper provides the driving force without a separate chuck. Ensure the spindle and shank are clean to prevent runout. The bit is not suited for hand-held drills lacking a taper socket or for applications requiring a different shank style or point geometry.

Questions about this item
How can I verify the 118-degree point is cutting correctly after installing the 53155 bit?
A properly sharpened 118-degree point produces equal-length chips from both cutting lips and a centered hole; measure the hole diameter to confirm it matches the 55/64-inch size.
What comes with the 53155 taper shank drill and what must I supply?
The box contains the 53155 high-speed steel drill with black-oxide finish and #3 Morse taper shank; you must provide a machine spindle or sleeve that accepts a #3 Morse taper.
