PCD diamond router bit Z2+2 D19,05 I35 L95 S19,05 H2,5 RH

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

Index: DTN.19.035.19.5SR

The industrial diamond milling 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 features a Z2+2 - blade arrangement of polycrystalline diamond (PCD) tips arranged on four working spirals, supported by a frontal plate made of sintered carbide (HM). The cutter shaft consists of a body made of high-hardness steel (> 28 HRC). This construction facilitates the free removal of dust, while the ground gripping part in a tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and ensures an excellent edge condition after machining. 

Design advantages and technical properties:

• Z2+2 geometry based on four spirals: A design that provides high cutting performance and excellent surface finishing standard of the material while maintaining high operational stability.
• Laser processing of cutting edges (ablation): DIA blade profiles are finished directly with a laser beam, which allows for edge radii at the level of 15 µm and guarantees a cutting surface free from micro-chips.
• Polished chip grooves and entry zone: The smoothed rear part of the PCD diamond plate combined with capacious chip channels prevents the accumulation of residue and facilitates quick dust removal from the cutting zone.
• Low roughness of the gripping part: The shaft surface with a roughness index of Ra ≤ 0.3 µm secures the cutter against rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the tight G2.5 class (according to ISO/EN) reduces noise and mitigates vibrations generated at high speeds.
• Regrinding capability: depending on the height of the applied diamond tip: tip H = 2.0 mm allows for 2 times sharpening, tip H = 2.5 mm allows for 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 allow for sharpening up to 4–6 times.

Intended use and application range:

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

It performs excellently in the processing of materials such as: raw and laminated MDF board, raw and laminated particle board, as well as raw and laminated plywood.
