PCD diamond router bit Z2+2 D15,88 I30 L94 S19,05 H2,5 RH

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

Index: DTN.15.030.19.5SR

The industrial diamond cutter from the DTN group was created for specialised formatting, nesting, and precise finishing operations on overhead spindle milling machines and CNC centres. The tool uses a blade arrangement Z2+2 -  polycrystalline diamond (PCD) tips are arranged on four working spirals, supported by a front tip made of sintered carbide (HM). The shank of the cutter is made of high-hardness steel (> 28 HRC). This construction facilitates the free removal of dust, while the ground clamping part with a tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and guarantees an excellent edge condition after machining. 

Design advantages and technical properties:

• Z2+2 geometry based on four spirals: This configuration provides high cutting efficiency and an excellent standard of surface finish while maintaining great operational stability.
• Laser treatment of cutting edges (ablation): The profiles of the DIA tips are finished directly with a laser beam, achieving edge radii of around 15 µm and guaranteeing a cutting surface free from micro-chipping.
• Polished chip grooves and cutting area: The smoothed rear part of the PCD diamond tip combined with ample chip channels prevents material from sticking and facilitates quick dust removal from the cutting zone.
• Low roughness of the clamping part: The surface of the shank with a roughness indicator of Ra ≤ 0.3 µm secures the cutter from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in a high G2.5 class (according to ISO/EN) reduces noise and vibrations generated at maximum speeds.
• Regeneration capability: Depending on the height of the used diamond tip: tip H = 2.0 mm allows for 2 sharpening, tip H = 2.5 mm allows sharpening a maximum of 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow sharpening a maximum of 3–4 times, while tips H = 4.0 mm / H = 4.5 mm allow 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 works excellently for machining materials such as: raw and laminated MDF boards, raw and laminated particle boards, and raw and laminated plywood.
