31/64-Inch HSS Jobber Drill Bit
This Westward drill bit is a fractional-inch cutting tool made from high-speed steel with a black-oxide finish. It measures 31/64 inches in diameter and features a conventional 118-degree point angle. The jobber-length design suits general-purpose drilling in metal, wood and plastic.
Suited for general workshop drilling
Machinists, maintenance technicians and hobbyists who need a 0.4844-inch hole in ferrous or non-ferrous materials will find this bit appropriate. It is not intended for coolant-through operations, deep-hole drilling beyond standard jobber length, or specialised angle and pitch locating tasks despite the category listing.
Fits standard drill chucks and frees up bit changes
The straight shank seats in any three-jaw chuck or collet sized for 31/64-inch tooling. Its black-oxide surface resists corrosion and reduces galling, letting the operator swap bits less often during repetitive production runs.

Questions about this item
Will the 31/64" shank fit the chuck on my existing drill?
The bit has a 31/64 inch diameter shank, so it requires a drill chuck that opens to at least .4844 inches or 1/2 inch capacity.
How does the 118° conventional point perform compared to older split-point bits I already own?
The 118° conventional point is a general-purpose geometry; it may walk more on hard surfaces than a split-point design and requires more feed pressure to start the hole.
What should I check to confirm the bit is cutting correctly after I start drilling?
Look for continuous, spiralling chips and a clean hole wall; the black oxide finish should show even wear on the cutting lips without blueing or chipping.
