5/16" HSS Jobber Drill Bit
This 5/16 inch high-speed steel drill bit is designed for general-purpose drilling in metal, wood and plastic. The fractional size and 118-degree conventional point suit maintenance, fabrication and automotive tasks where a standard jobber length is required.
Black Oxide Finish and Conventional Point
The black oxide coating provides corrosion resistance and reduces chip welding during extended use. A conventional 118-degree point centres quickly without a pilot hole, while the straight shank fits common three-jaw chucks for fast bit changes on the job site.
Replaces Worn or Undersized Bits
Swapping a dull or smaller-diameter bit for this 5/16 inch tool restores clean hole quality and accurate sizing. The upgrade is worthwhile when existing bits no longer hold an edge or when a project demands the precise .3125 decimal equivalent for bolt clearance or tapping operations.

Questions about this item
What material does the 118-degree point angle apply to?
The 118-degree conventional point is ground on high-speed steel suited for general-purpose drilling.
What shank size fits a 5/16-inch jobber-length bit?
The bit has a straight 5/16-inch shank that matches the drill diameter for standard three-jaw chucks.
How do you avoid walking when starting a 5/16-inch HSS bit?
Centre-punch the workpiece, then apply steady pressure at low speed until the 118-degree point engages fully.
