KnKut KK12SP-5/8 Step-Point Drill, 1/2-Inch Shank
KnKut KK12SP-5/8 supplies the five-eighths-inch hole size as a single step-point twist bit. Its half-inch reduced shank is smaller than the cutting diameter by one eighth of an inch, so use the five-eighths measurement for the opening and the half-inch measurement for chuck fit.
Specifications and included details
- 5/8-inch cutting diameter and 1/2-inch reduced shank with three flats.
- Step-point design combining split-tip and stepped cutting-end geometry.
- Listed molybdenum HSS with high vanadium content and salt nitride treatment.
- Jobber-length designation; explicit inventory is one bit.
Before ordering
Verify the five-eighths-inch required opening, chuck capacity and material-specific equipment limits. Obtain actual overall and flute lengths when the job requires a defined reach; jobber length alone does not provide those numbers. Follow manufacturer guidance for enlarging an existing hole rather than assuming every starting-hole size is suitable.
