PCD diamond router bit Z2+2 D12 I25 L77 S12 H2,5 LH

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

Index: DTN.12.025.12.0SL

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 features a blade configuration Z2+2 -  with polycrystalline diamond (PCD) inserts arranged on four cutting spirals, supported by a front plate made of sintered carbide (HM). The cutter's body is made of high-hardness steel (> 28 HRC). This design facilitates easy dust removal, while the ground shank in tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and ensures 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 an excellent standard of surface finish while maintaining large operational stability.
• Laser processing of cutting edges (ablation): DIA blade profiles are finished directly with a laser beam, achieving edge radii at the level of 15 µm and guaranteeing a cutting surface free from micro-chipping.
• Polished chip grooves and cutting zone: The smoothed rear part of the PCD diamond insert combined with generous chip evacuation channels prevents material from sticking and facilitates swift dust removal from the cutting zone.
• Low roughness of the shank: The surface of the shank has a roughness index of Ra ≤ 0.3 µm, preventing the cutter from spinning in the holder and eliminating the risk of wear on the taper in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in a high-class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds.
• Regrinding capability: Depending on the height of the diamond insert used: insert H = 2.0 mm allows for 2-time sharpening, insert 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 inserts H = 4.0 mm / H = 4.5 mm allow for sharpening up to 4–6 times.

Intended use and scope:

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

It works perfectly for machining materials such as: raw and laminated MDF boards, raw and laminated particle boards, as well as raw and laminated plywood.
