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

Index: DTN.20.025.20.0SR

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

Construction advantages and technical properties:

• Z2+2 geometry based on four spirals: A configuration that provides high cutting efficiency and excellent surface finish standards while maintaining significant operational stability.
• Laser processing of cutting edges (ablation): DIA blade profiles are finished directly with a laser beam, achieving edge radii in the range of 15 µm and ensuring a cutting plane free of micro-chipping.
• Polished chip grooves and entry zone: The smoothed back of the PCD diamond insert combined with spacious chip channels prevents workpiece adhesion and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm secures the cutter from rotating 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 class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at high 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 permits a maximum of 2–3 sharpenings, H = 3.0 mm / H = 3.5 mm variants allow for a maximum of 3–4 sharpenings, while inserts H = 4.0 mm / H = 4.5 mm enable a maximum of 4–6 sharpenings.

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.
