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

Index: DTN.12.025.20.0SR

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 features a blade arrangement Z2+2 -  with polycrystalline diamond (PCD) inserts positioned on four cutting spirals, supported by a front insert made of sintered carbide (HM). The cutter's shank consists of a body made of high-hardness steel (> 28 HRC). This design facilitates the freestanding removal of dust, while the ground shank in a tight tolerance class of H6 minimises radial runout, protecting the spindle bearings and ensuring an excellent edge condition after machining. 

Construction 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): DIA cutting edge profiles are finished directly with a laser beam, which allows for edge radii at the level of 15 µm and ensures 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 build-up and facilitates rapid dust removal from the cutting zone.
• Low Roughness of the Shank: The surface of the shank with a roughness indicator of Ra ≤ 0.3 µm secures the cutter against spinning in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic Balancing to G2.5 Standard: Certified static-dynamic balancing in an advanced G2.5 class (according to ISO/EN) reduces noise and lessens vibrations generated at high speeds.
• Regrinding Capability: depending on the height of the applied diamond insert: an insert with H = 2.0 mm allows for 2-time sharpening, an insert with H = 2.5 mm enables sharpening a maximum of 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow for sharpening a maximum of 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm enable sharpening a maximum of 4–6 times.

Purpose and Scope of Use:

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

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