Polished Carbide
Ideal for Clean, Chip-free Cuts in MDF, Plywood and Hardwoods. The polished finish reduces friction and chip buildup, but lacks the wear resistance of coated or PCD tools. Good for moderate-speed applications.
Hardness: 1600-1700 HV
Tool Life:
Max Sustained Feed Rate: 8-10 m/min
Recommended Materials:
MDF, General Wood, Particle Board

2F Nano Carbide
Designed for high-performance wood and composite cutting, with NaCo coating providing superior heat resistance and tool life over uncoated carbide. Best for moderate-speed applications where finish quality is critical.
Hardness: 4000-4500 HV
Tool Life:
Max Sustained Feed Rate: 12-15 m/min
Recommended Materials:
MDF, Particle Board, Plywood, Composites

3F Nano Carbide
Offers improved durability and thermal protection over the 2F version, but with 50% higher feed rate capability thanks to the additional cutting edge, maximizing throughput. Advanced Micro-grain Carbide enhances edge retention and durability.
Hardness: 4000-4500 HV
Tool Life:
Max Sustained Feed Rate: 18-20 m/min
Recommended Materials:
MDF, Particle Board, Plywood, Composites

PCD (Polycrystalline Diamond)
Engineered for ultra-long life in abrasive materials like composites, particleboard and laminates. PCD tips outperform carbide by a wide margin in wear resistance while still maintaining excellent finsh quality.
Hardness: 8000-10,000 HV
Tool Life:
Max Sustained Feed Rate: 10-15 m/min
Recommended Materials:
MDF, Particle Board, Plywood, Composites

Single Flute Compression Spiral DLC
Ideal for ACM and Softwood. DLC coating providing superior heat resistance and tool life over uncoated carbide. Advanced Micro-grain Carbide enhances edge retention and durability.
Hardness: 4500 HV
Tool Life:
Max Sustained Feed Rate: 3-5 m/min
Recommended Materials:
ACM, MDF, Particleboard, PVC, Plastics
