PCD Diamond Cutter from the DTN Z2+2 Series – for Finishing, Nesting, and Formatting Operations

Index: DTN.12.025.12.0SR

The industrial diamond cutter from the DTN group has been designed for specialised formatting, nesting, and precise finishing operations on overhead spindle milling machines and CNC centres. The tool features a Z2+2 blade arrangement, with polycrystalline diamond (PCD) inserts placed on four cutting spirals, supported by a front insert made of sintered carbide (HM). The cutter's shaft is made of high-hardness steel (> 28 HRC). This design facilitates the free removal of dust, while the ground shank with a close tolerance class of H6 eliminates radial runout, protecting spindle bearings and ensuring an excellent edge condition after machining. 

Design Advantages and Technical Properties:

• Z2+2 Geometry based on Four Spirals: A configuration that provides high cutting efficiency and an excellent finishing standard for the material's surface while maintaining great work stability.
• Laser Edge Processing (Ablation): The blade profiles are finished directly with a laser beam, achieving edge radii of around 15 µm and ensuring a cutting plane free of micro-chipping.
• Polished Chip Flutes and Cutting Edge Zone: The smoothed rear part of the PCD diamond insert combined with capacious chip channels prevents material build-up and facilitates quick dust removal from the cutting zone.
• Low Roughness of the Shank: The surface of the shank has a roughness index of Ra ≤ 0.3 µm, securing the cutter against rotation in the holder and eliminating the risk of wear on the cone in the spindle.
• Dynamic Balancing to G2.5 Standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Regeneration Capability: Depending on the height of the diamond insert used: an insert H = 2.0 mm allows for 2 re-sharpenings, an insert H = 2.5 mm enables sharpening up to 2–3 times, variations of H = 3.0 mm / H = 3.5 mm allow for sharpening up to 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm enable sharpening up to 4–6 times.

Intended Use and Application Range:

The tool is designed for cutting, nesting, contour milling, and grooving operations.

It performs excellently when machining materials such as: raw and laminated MDF board, raw and laminated particle board, and raw and laminated plywood.
