A 19/32 in high-speed steel drill bit with a 118° point angle and 1/2 in reduced shank for general-purpose drilling
The Chicago-Latrobe 55438 is a reduced-shank drill bit designed for machinists and maintenance technicians who need to bore 19/32 inch holes using a standard 1/2 inch drill chuck. It is manufactured from high-speed steel with a black oxide finish for general-purpose metal cutting. This tool is not for buyers who need a full 19/32 inch shank or a different point geometry for specialised materials.
The single specification that decides fit is the 118 degree point angle, which is the standard geometry for drilling mild steel, cast iron and similar ferrous metals in a handheld or stationary drill press. A different angle would be required for hard alloys, stainless steel or non-metallic materials where chip evacuation and heat control demand a specialised profile. The high-speed steel substrate supports this standard cutting action.
The 1/2 inch reduced shank allows the bit to be secured in any drill press or heavy-duty hand drill equipped with a standard 1/2 inch capacity chuck, freeing the user from sourcing a larger-capacity spindle. The black oxide finish helps retain cutting lubricant during operation. It does not suit machines that accept only straight-shank bits matching the full cutting diameter.

The bit makes a 19/32 in diameter hole, while the shank is turned down to 1/2 in so it fits a standard 1/2 in chuck.
The 118° point is the general-purpose angle for high-speed steel bits; it centres well and cuts cleanly in mild steel and similar materials.
Yes — the shank is precisely 1/2 in, so it seats directly in any 1/2 in keyed or keyless chuck.
