KnKut KK5-1/4 1/4-Inch M7 HSS Jobber Drill Bit
KnKut KK5-1/4 is a quarter-inch jobber drill with a conventional split-point cutting end, distinct from the larger reduced-shank step-point models in the catalog. Its listed M7 molybdenum HSS and salt nitride treatment describe the tool material and surface process for selecting a size-specific metal drill.

- 1/4-inch nominal cutting diameter; one drill bit included.
- M7 molybdenum high-speed steel with listed high vanadium content.
- Salt nitride treatment and 135-degree split point.
- Jobber-length designation; listed applications include stainless steel and titanium alloys.
Before ordering
Confirm the quarter-inch opening and verify actual shank, overall and flute dimensions for the setup; those dimensions are not itemized here. Choose cutting conditions for the metal and machine. A split point does not guarantee pilot-free drilling or a lower cost per hole in every application.
