53/64" Silver & Deming Drill

The Chicago-Latrobe 55453 is a high-speed steel drill bit sized at 53/64 inch with a 118 degree point angle. Its black oxide finish adds wear resistance for general machining tasks. The reduced 1/2 inch shank allows use in standard drill chucks. It suits maintenance and fabrication work requiring this specific large diameter.

Reduced shank limits chuck compatibility

The 1/2 inch reduced shank fits common three-jaw chucks but cannot be held in collets or chucks requiring a full-diameter shank. Torque transmission is lower than a straight-shank bit of the same flute size. The 118 degree point is optimised for mild steel and cast iron rather than hard alloys. Deep holes may need frequent withdrawal to clear chips.

53/64 inch diameter decides fit

The single specification that determines whether this is the right part is the 53/64 inch drill bit size. If the hole required is larger or smaller, this bit will not produce the correct diameter. Buyers who need a different fractional size, metric equivalent, or a step drill for multiple diameters should select another tool.

Questions about this item

Should I pick the 53/64 in bit or a smaller size?

Choose the 53/64 in bit when the hole must be that exact diameter; select a smaller size only if the application calls for a narrower hole.

What does the 118 degree point angle mean once the bit is in the drill?

The 118 degree point angle gives a conventional cutting profile suited for general-purpose drilling in steel and similar materials.

How does the 1/2 reduced shank affect what chucks it fits?

The 1/2 reduced shank allows the bit to be clamped in any standard 1/2 in capacity drill chuck.
