PCD diamond router bit Z2+2 D20 I45 L103 S20 H2,5 LH

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

Index: DTN.20.045.20.0SL

The industrial diamond cutter from the DTN group has been designed for specialised formatting operations, nesting, and precise finishing of materials on overhead spindle milling machines and CNC centres. The tool employs a blade arrangement Z2+2 -  with polycrystalline diamond (PCD) tips distributed on four working spirals, supported by a front plate made of sintered carbide (HM). The cutter's shaft consists of a body made of high-hardness steel (> 28 HRC). This construction facilitates free dust extraction, while the ground shank with a tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and guarantees an excellent cutting edge condition after processing. 

Construction advantages and technical properties:

• Z2+2 geometry based on four spirals: A configuration that provides high cutting performance and an excellent surface finish standard while maintaining high work stability.
• Laser treatment of cutting edges (ablation): The profiles of the DIA blades are finished directly with a laser beam, which allows for edge radii at the level of 15 µm and guarantees a cutting plane free from micro-chipping.
• Polished chip grooves and cutting area: The smoothed back part of the PCD diamond tip combined with capacious chip channels prevents material adhesion and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The shaft surface with a roughness index of Ra ≤ 0.3 µm secures the cutter from turning in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balance in G2.5 standard: Certified static-dynamic balancing in an exceptional G2.5 class (according to ISO/EN) reduces noise and vibration generated at high speeds.
• Regeneration capability: depending on the height of the applied diamond tip: tip H = 2.0 mm allows for 2-time sharpening, tip H = 2.5 mm enables sharpening up to 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow for sharpening up to 3–4 times, while tips H = 4.0 mm / H = 4.5 mm enable sharpening up to 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 particle boards, as well as raw and laminated plywood.
