31/32 in drill bit with 1/2 reduced shank
This Chicago-Latrobe 55462 drill bit fits a 1/2 inch chuck despite its large 31/32 inch cutting diameter. It targets machinists and maintenance technicians who need to drill near-one-inch holes without a large-capacity drill press. The reduced shank design allows use on standard portable drills and bench-top machines.
118 degree point angle for general-purpose drilling
The 118 degree point angle is the critical specification that determines material suitability. This angle performs reliably in mild steel, cast iron and similar ferrous metals. It is not optimised for hard alloys or non-ferrous materials where a split point or different angle would reduce walking and heat buildup.
High speed steel body with black oxide finish
The high speed steel construction provides wear resistance for repetitive holemaking in machine-shop environments. Black oxide finish adds lubricity and corrosion protection during extended use. The bit handles standard production drilling in ferrous metals but lacks the cobalt content or specialised geometry needed for stainless steel or high-temperature alloys.

Questions about this item
What hole size does the 31/32 in drill bit actually produce in metal?
It cuts a 31/32 in diameter hole, just under one inch, suitable for clearance or tapping operations in steel and other machinable metals.
How does the 1/2 reduced shank affect compatibility with my drill chuck?
The shank is turned down to 1/2 in so the bit fits any standard 1/2 in keyed or keyless chuck despite the larger cutting diameter.
What length and clearance do I need to accommodate this bit in my drill press?
The bit follows standard Silver & Deming overall length for a 31/32 in cutting diameter, so allow full spindle travel plus workpiece thickness when setting up.
