October 13, 2026 Kyocera KTKF-JCT Cut-off Holders for Machining
The Kyocera KTKF-JCT Cut-off holder is designed for small parts machining with high-pressure coolant support. Developed by Kyocera, this specialized cut-off toolholder directs internal coolant flow directly to the cutting zone, providing superior chip control and extended insert service life when processing difficult-to-cut materials.
Key Features of Kyocera KTKF-JCT Cut-off Holders
High-pressure coolant delivery plays a critical role in controlling chip fragmentation and reducing cutting temperature during small-parts turning operations:
- Dual-Direction Coolant Discharge: Discharges coolant in two directions toward the rake surface of the insert while simultaneously directing coolant from the flank face to suppress flank wear.
- High Flow Rate Performance: Delivers up to 1.3 times higher coolant flow rate compared to conventional toolholders under pump pressures of 1 to 3 MPa.
- Superior Chip Shredding: Finely breaks continuous chips into small manageable pieces, preventing chip birdnesting when machining stainless steel (SUS304) and titanium alloys (Ti-6Al-4V / TAB6400).
- Extended Insert Service Life: Ample fluid delivery directly onto the cutting edge reduces thermal stress and nose wear during high-speed cutting.
Machining Performance & Evaluation Parameters
Internal testing under 1.5 MPa oil-based coolant pressure demonstrates significantly lower flank wear on Ti-6Al-4V workpieces over 70 minutes of continuous cutting compared to conventional holders, alongside reliable chip control at feed rates ranging from 0.01 to 0.03 mm/rev.
