Diamond PCD Cutter from the DTN Z2+2 Series – for finishing, nesting and formatting machining

Index: DTN.12.025.16.0SL

The industrial diamond cutter from the DTN group has been designed for specialized formatting, nesting, and precise finishing operations on overhead spindle milling machines and CNC centres. The tool employs a blade arrangement of Z2+2 -  polycrystalline diamond (PCD) inserts positioned on four cutting spirals, supported by a front insert made of sintered carbide (HM). The cutter shaft is made of steel with increased hardness (> 28 HRC). This construction facilitates the free evacuation of dust, while the ground shank in the tight tolerance class H6 eliminates radial run-out, which protects the spindle bearings and guarantees excellent edge condition after machining.

Design advantages and technical properties:

• Z2+2 geometry based on four spirals: The arrangement delivers high cutting efficiency and excellent surface finish standards while maintaining high operational stability.
• Laser processing of cutting edges (ablation): The DIA blade profiles are finished directly with a laser beam, achieving edge radii of around 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished chip grooves and entry zone: The smoothed back part of the PCD diamond insert combined with capacious chip channels prevents material adhesion and facilitates rapid dust removal from the cutting area.
• Low roughness of the shank: The shaft surface with a roughness index of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the high G2.5 class (according to ISO/EN) reduces noise and minimizes vibrations generated at the highest speeds.
• Regrinding capability: Depending on the height of the applied diamond insert: the H = 2.0 mm insert allows for 2 times sharpening, the H = 2.5 mm insert enables sharpening up to 2–3 times, the H = 3.0 mm / H = 3.5 mm variants allow sharpening up to 3–4 times, while the H = 4.0 mm / H = 4.5 mm inserts allow sharpening up to 4–6 times.

Intended use and application range:

The tool is intended for cutting, nesting, peripheral milling, and routing operations.

It performs excellently in processing materials such as: raw and laminated MDF boards, raw and laminated chipboards, and raw and laminated plywood.
