PCD diamond router bit Z2+2 D20 I25 L90 S20 H2,5 LH

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

Index: DTN.20.025.20.0SL

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 system Z2+2 -  polycrystalline diamond (PCD) tips arranged on four working spirals, supported by a front plate made of sintered carbide (HM). The cutter's body is constructed from high-hardness steel (> 28 HRC). This design facilitates easy dust removal, while the ground shank with a tight tolerance class of H6 eliminates radial runout, safeguarding the spindle bearings and ensuring excellent edge condition after machining. 

Structural advantages and technical properties:

• Z2+2 geometry based on four spirals: A configuration that provides high cutting efficiency and excellent surface finish standard for the material while maintaining great operational stability.
• Laser processing of cutting edges (ablation): The DIA blade profiles are finished directly with a laser beam, achieving edge radii on the order of 15 µm and ensuring a cutting plane free from micro-chipping.
• Polished chip grooves and cutting zone: The smoothed rear part of the PCD diamond tip combined with voluminous chip channels prevents material from sticking and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The shank surface with a roughness index of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing at G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and minimizes vibrations generated at the highest speeds.
• Regeneration capability: Depending on the height of the applied diamond tip: tip H = 2.0 mm allows for 2 sharpening cycles, tip H = 2.5 mm allows for 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 tips H = 4.0 mm / H = 4.5 mm allow for sharpening a maximum of 4–6 times.

Intended use and applications:

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

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