PCD diamond router bit Z2+2 D18 I25 L84 S20 H2,5 RH

PCD diamond cutter from the DTN Z2+2 series – for finishing, nesting, and formatting

Index: DTN.18.025.20.0SR

The industrial diamond cutter from the DTN group is designed for specialised formatting operations, nesting, and precise finishing of materials on overhead spindle milling machines and CNC centres. The tool uses a blade arrangement Z2+2 -  where polycrystalline diamond (PCD) inserts are arranged on four working spirals, supported by a front insert made of sintered carbide (HM). The cutter shaft comprises a body made of high-hardness steel (> 28 HRC). This construction facilitates the free removal of dust, while the ground shank in a tight tolerance class 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 standard of material surface finish while maintaining great operational stability.
• Laser edge treatment (ablation): The blade profiles are finished directly with a laser beam, achieving edge radii on the order of 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished chip grooves and cutting zone: The smoothed rear part of the PCD diamond insert, combined with capacious chip channels, prevents the adherence of cuttings and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The surface of the shaft with a roughness index of Ra ≤ 0.3 µm secures the cutter against rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in an exacting class G2.5 (according to ISO/EN) minimises noise and reduces vibrations generated at high speeds.
• Regeneration capability: Depending on the height of the diamond insert used: an insert H = 2.0 mm allows for 2 times sharpening, an insert H = 2.5 mm permits 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.

Intended use and application range:

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

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