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

Index: DTN.20.055.20.0SR

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 employs a blade arrangement of Z2+2 - polycrystalline diamond (PCD) tips distributed over four working spirals, supported by a front tip made of sintered carbide (HM). The cutter's body is constructed from high-hardness steel (> 28 HRC). This design facilitates free dust removal, while the ground shank in a tight tolerance class of H6 eliminates radial runout, protecting the spindle bearings and ensuring 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 surface finish standard while maintaining great work stability.
• Laser Edge Treatment (Ablation): The DIA blade profiles are finished directly with a laser beam, allowing for edge radii of around 15 µm and guaranteeing a cutting face free from micro-chipping.
• Polished Flute and Rake Face: The smoothed rear part of the PCD diamond tip combined with capacious flutes prevents material from sticking and enhances rapid dust removal from the cutting zone.
• Low Roughness of the Shank: The shank surface has a roughness index of Ra ≤ 0.3 µm, securing the cutter against spinning in the holder and eliminating the risk of cone wear 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.
• Regrinding Capability: Depending on the height of the diamond tip used: tip H = 2.0 mm allows for 2 regrinds, tip H = 2.5 mm enables a maximum of 2–3 regrinds, variants H = 3.0 mm / H = 3.5 mm allow for a maximum of 3–4 regrinds, while tips H = 4.0 mm / H = 4.5 mm enable regrinding up to 4–6 times.

Intended Use and Application Range:

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

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