PCD diamond router bit Z2+2 D18 I35 L97 S20 H2,5 RH

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

Index: DTN.18.035.20.0SR

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 uses a blade arrangement Z2+2 -  with polycrystalline diamond (PCD) inserts distributed across four cutting spirals, supported by a front insert made of sintered carbide (HM). The cutter shaft consists of a body made of high-hardness steel (> 28 HRC). This design facilitates the free removal of dust, while the ground shank with a tight tolerance class H6 eliminates radial runout, protecting spindle bearings and ensuring excellent edge condition after machining. 

Construction advantages and technical properties:

• Z2+2 geometry based on four spirals: An arrangement providing high cutting efficiency and an excellent finish standard for the material surface while maintaining high operational stability.
• Laser processing of cutting edges (ablation): DIA blade profiles are finished directly with a laser beam, allowing for edge radii of around 15 µm and ensuring a cutting surface free of micro-chipping.
• Polished chip grooves and cutting zone: The smoothed rear part of the PCD diamond insert combined with capacious chip channels prevents sticking of the chips 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 protects the cutter from rotating in the holder and eliminates the risk of wear on the spindle conical surface.
• Dynamic balancing in norm G2.5: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and vibration generated at high speeds.
• Regrinding possibility: depending on the height of the used diamond insert: insert H = 2.0 mm allows for 2 regrinds, insert H = 2.5 mm enables regrinding up to 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow for regrinding up to 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm permit regrinding up to 4–6 times.

Purpose and application range:

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 particleboard, and raw and laminated plywood.
