KnKut KK12SP-7/8 Step-Point Drill, 1/2-Inch Shank
KnKut KK12SP-7/8 places a seven-eighths-inch cutting diameter on a half-inch reduced shank. Choose it by the exact opening requirement, not the smaller chuck connection; fitting the shank is only one part of confirming the machine can handle this larger drill.
Specifications and included details
- 7/8-inch cutting diameter; 1/2-inch reduced shank with three flats.
- Step-point geometry with split tip.
- Listed molybdenum HSS with high vanadium content and salt nitride treatment.
- Jobber-length designation; no numeric overall or flute length supplied.
Before ordering
Confirm the seven-eighths-inch opening and machine capacity for the material. The three-flat shank does not create a universal anti-slip guarantee or compatibility with every half-inch machine. Check actual bit length and tool clearance if the setup has limited space.
Product questions and answers
Is this the same cutting size as a 15/16-inch bit?
No. Seven eighths is 14/16 inch, one sixteenth smaller than 15/16 inch.
Does a half-inch chuck connection guarantee drill capacity?
No. Verify both shank fit and the drill's supported cutting diameter for the actual material.
Does jobber length provide an exact dimension here?
No numeric overall or flute length is provided. Confirm those dimensions if reach or clearance is critical.
