October 8, 2026 Kyocera SIGC High-Precision Small Internal Grooving Tools
The Kyocera SIGC high-precision internal grooving tool series is engineered for small-diameter internal machining starting at a minimum cutting diameter of ø8 mm. Manufactured by Kyocera, this specialized tooling system incorporates a newly developed axial clamping structure, double coolant hole channels, and PR1725 MEGACOAT NANO PLUS coating to deliver exceptional stability and long tool life during precision internal slotting operations.
Firm Insert Clamping for High-Precision Machining
The core innovation behind the Kyocera SIGC system lies in its axial pull clamping mechanism designed to eliminate cutting edge displacement under heavy radial loads:
- Axial Pull Clamping Action: Pulls the bottom surface of the insert tightly in the axial direction across a large contact area, providing superior rigidity compared to point-contact competitor designs.
- Anti-Rotation Geometry: Prevents angular deflection and Z-axis movement of the insert during continuous and light interrupted cuts.
- Cutting Edge Position Stability: Internal evaluations demonstrate near-zero cutting edge movement in the Z direction and minimal front cutting edge angle variation after repeated passes.
Coolant Delivery and Bar Selection
To support deep-hole internal grooving and optimal chip removal, the Kyocera SIGC series features advanced holder and substrate options:
- Double Coolant Holes: Dual internal coolant channels direct high-pressure fluid directly onto the rake face and flank of the insert to optimize chip evacuation and thermal management.
- PR1725 Grade Technology: Uses MEGACOAT NANO PLUS coating over a tough carbide substrate to minimize wear and edge chipping.
- Steel and Carbide Shank Bars: Available in steel shanks for standard overhangs and solid carbide shank Excelente Bars for high-rigidity, chatter-free deep internal boring.
