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

Index: DTN.19.044.19.5SR

The industrial diamond cutter from the DTN group has been designed for specialised formatting operations, nesting, and precise finishing of materials on overhead spindle milling machines and CNC centres. The tool features a blade arrangement Z2+2 -  with polycrystalline diamond (PCD) inserts placed on four working spirals, supported by a solid carbide (HM) front insert. The cutter body is made from high-hardness steel (> 28 HRC). This construction facilitates free dust removal, while the ground shank in strict tolerance class H6 eliminates radial run-out, ensuring spindle bearing protection and guaranteeing an excellent edge condition after processing. 

Design Advantages and Technical Properties:

• Z2+2 Geometry based on four spirals: A design that offers high cutting efficiency and an excellent standard of material surface finishing while maintaining high operational stability.
• Laser machining of cutting edges (ablation): DIA blade profiles are finished directly with a laser beam, allowing for edge radii of about 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished chip grooves and cutting area: The smooth rear part of the PCD diamond insert combined with capacious chip channels prevents material build-up and facilitates rapid dust removal from the cutting zone.
• Low roughness of the shank: The shank surface with a roughness value of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the high standard of G2.5 (according to ISO/EN) reduces noise and minimises vibrations generated at high speeds.
• Regrindability: Depending on the height of the diamond insert used: an insert H = 2.0 mm allows for 2 times sharpening, an insert H = 2.5 mm allows for sharpening up to 2–3 times, variants 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 allow for sharpening up to 4–6 times.

Intended Use and Scope of Application:

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

It works perfectly in processing materials such as raw and laminated MDF boards, raw and laminated chipboards, and raw and laminated plywood.
