Precision drilling for metalwork
The Westward 15/32 inch HSS black oxide jobber drill bit is built for machinists and maintenance technicians who need accurate holes in steel and alloy. Its conventional 118 degree point centres quickly without a pilot hole. The fractional size matches legacy drawings and imperial hardware.
Black oxide finish reduces friction
The surface treatment lowers chip welding and extends edge life when cutting ferrous metals. High speed steel construction resists heat buildup during prolonged drilling cycles. No coolant-through capability means external lubrication is required for deep holes.
Straight shank fits standard chucks
The jobber length shank seats in any three jaw chuck or collet sized for fractional inch bits. California Proposition 65 warnings apply to chemicals present in the coating. Users must supply cutting fluid and verify workpiece clamping before starting.

Questions about this item
How often will the 15/32" HSS bit need resharpening or replacement?
Resharpen when the 118-degree conventional point dulls; high-speed steel can be reground multiple times before the 0.4688-inch diameter wears below usable tolerance.
What limit appears first during continuous drilling with this jobber-length bit?
Heat buildup at the black-oxide surface softens the edge faster than flute clogging, so cutting speed must drop once the shank feels hot.
How much noise, heat and power draw should I expect when running this drill bit all day?
The bit itself adds no power draw; noise and heat come from the drill motor, while the black-oxide coating reduces friction heat at the cutting lips.
