Kyocera KGD KGDF Grooving and Cut-Off Tools
The Kyocera KGD KGDF grooving and cut-off tooling series provides exceptional chip control, high clamping rigidity, and extended insert life across a comprehensive range of external, internal, and face grooving operations. Developed by Kyocera, this versatile system combines advanced MEGACOAT and MEGACOAT NANO PVD coating technologies with an expansive lineup of specialized chipbreakers and toolholder configurations to maximize productivity in metalworking shop floors.
Diverse Chipbreaker Options for Superior Chip Control
The Kyocera KGD KGDF lineup offers optimized chipbreaker geometries designed to eliminate chip packing, edge chipping, and surface scratches during grooving, cut-off, and profiling:
- GM Chipbreaker: General-purpose choice for steel grooving and traversing, offering smooth chip curl over a wide feed range.
- PH & GL Chipbreakers: PH for high-feed roughing and heavy interrupted cuts; GL for precise low-feed grooving.
- GS & PQ Chipbreakers: GS for low-cutting-force operations on thin-walled or low-rigidity workpieces; PQ for finishing-medium cut-off.
- PM & PF Chipbreakers: Dedicated cut-off geometries (PM for general medium feed, PF for smooth low feed).
- CM Chipbreaker: Specialized geometry engineered for smooth copying and profiling applications.
MEGACOAT & MEGACOAT NANO Grade Technology
To resist severe thermal stress and mechanical shock in continuous and interrupted grooving, Kyocera KGD KGDF inserts feature high-hardness coating grades:
- PR1225 (MEGACOAT): First choice for general steel grooving and cut-off, balancing wear and fracture toughness.
- PR1215 (MEGACOAT): High wear resistance specialized for cast iron turning.
- PR1535 (MEGACOAT NANO): High-oxidation-resistant grade engineered for stainless steel machining and heavy interrupted cuts.
Toolholder Architecture & W Grip Clamping
The Kyocera KGD KGDF system provides flexible holder options suited for both high-volume dedicated production and high-mix job shops:
- Integral Type Toolholders: Monoblock shanks optimized for compact CNC lathes and automatic Swiss-type machines with specific overhang requirements.
- SwitchBlade Type Toolholders: Modular blade system allowing operators to switch between external and face grooving blades at minimal tooling cost.
- W Grip Clamping System (KGDF Face Grooving): Interlocking V-groove clamping prevents side-slip, enhances indexing accuracy, and provides unmatched stability under high lateral cutting forces.
