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

Index: DTN.12.025.16.0SR

The industrial diamond cutter from the DTN group has been designed for specialised formatting operations, nesting, and precision finishing of materials on overhead spindle milling machines and CNC centres. The tool features a blade arrangement Z2+2 -  with polycrystalline diamond (PCD) inserts arranged across four working spirals, supported by a front plate made of sintered carbide (HM). The cutter body is made from high-hardness steel (> 28 HRC). This construction facilitates the efficient dust removal, while the ground shank in a tight tolerance class H6 eliminates radial runout, protecting the spindle bearings and ensuring excellent edge condition after machining. 

Structural Advantages and Technical Properties:

• Z2+2 Geometry  based on four spirals: A configuration that provides high cutting efficiency and an excellent standard of surface finish while maintaining great operational stability.
• Laser Edge Treatment (Ablation): The DIA blade profiles are finished directly by a laser beam, allowing for edge radii levels of 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished Flute and Rake Area: The smoothed back side of the PCD diamond insert combined with capacious chip flutes prevents material build-up and facilitates quick dust removal from the cutting area.
• Low Roughness of the Shank: The shank surface with a roughness index of Ra ≤ 0.3 µm secures the cutter against rotation in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic Balancing to G2.5 Standards: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and minimizes vibrations generated at high rotational speeds.
• Regeneration Capability: Depending on the height of the diamond insert used: insert H = 2.0 mm allows for 2 sharpening cycles, insert H = 2.5 mm enables sharpening up to 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow sharpening up to 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm permit sharpening up to 4–6 times.

Intended Use and Scope:

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

It performs excellently in machining materials such as: raw and laminated MDF board, raw and laminated chipboard, as well as raw and laminated plywood.
