KnKut KK12SP-1 1-Inch Step-Point Bit, 1/2-Inch Shank
KnKut KK12SP-1 pairs a one-inch cutting diameter with a half-inch reduced shank. The smaller shank allows the connection size to differ from the hole size; it does not establish that every half-inch drill has the torque or operating capacity for a one-inch hole in the selected material.
Specifications and included details
- 1-inch cutting diameter and 1/2-inch reduced shank with three flats.
- Split-tip step-point geometry on a twist drill.
- Listed hi-molybdenum tool steel with high vanadium content and salt nitride treatment.
- Jobber-length designation; listed purchase includes one bit.
Before ordering
Verify chuck opening, machine capacity and workpiece requirements for the 1-inch diameter. No numeric overall or flute length is supplied here. Step point describes the cutting-end design; this is a fixed-diameter twist bit, not a conical multi-size sheet-metal step drill.
Product questions and answers
Does the half-inch shank mean it cuts a half-inch hole?
No. The cutting diameter is 1 inch. Half an inch is the reduced connection size.
Can it replace a conical step drill covering several diameters?
No. This is a one-inch fixed-diameter twist drill with step-point geometry, not a multi-size conical bit.
Does it include a drill or chuck adapter?
The explicit inventory lists one KK12SP-1 drill bit. A drill or adapter is not itemized.
