1-5/32in HSS Silver and Deming Drill Bit
This Drill America bit is a high-speed steel Silver and Deming drill designed for large-diameter hole making. It features a 1-5/32 inch cutting diameter with a decimal equivalent of 1.1563 inches. The bit has a 1/2 inch reduced shank with three-flatted sides for secure chuck grip. Surface-treated flutes and a 3 inch flute length support chip evacuation in deep holes.
Suited for machinists and maintenance technicians
This bit suits machinists and maintenance technicians drilling large holes in metal stock using standard 1/2 inch chucks. The three-flatted shank prevents slippage under high torque. Users needing a full 1-5/32in shank diameter or a different flute length should look at other options. Builders requiring carbide tips or cobalt alloy construction will need a different tool.

Questions about this item
How do I install the 1-5/32in HSS drill bit with its 1/2 reduced shank and 3-flatted shanks, and what step do people get wrong?
Insert the reduced shank fully into the drill chuck so the three flats seat against the jaws, then tighten securely; the common error is clamping only on the round portion, which lets the bit slip under load.
What maintenance or replacement will the 1-5/32in Silver and Deming drill bit need later?
Resharpen the HSS cutting edges when they dull, and replace the bit if the flutes wear down or the 3-flatted shank becomes rounded, as this affects grip in the chuck.
