PCD diamond router bit Z2+2 D12 I35 L94 S12 H2,5 LH

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

Index: DTN.12.035.12.0SL

The industrial diamond milling cutter from the DTN group is designed for specialised formatting operations, nesting, and precision finishing of materials on overhead spindle milling machines and CNC centres. The tool uses a blade arrangement Z2+2 -  consisting of polycrystalline diamond (PCD) inserts arranged on four working spirals, supported by a front cutting plate made of sintered carbide (HM). The cutter’s body is made of high-hardness steel with a hardness greater than 28 HRC. This construction facilitates the free removal of dust, while the ground shank in a tight tolerance class H6 eliminates radial runout, protecting the spindle bearings and ensuring excellent edge condition after processing. 

Design advantages and technical properties:

• Z2+2 geometry based on four spirals: A system that provides high cutting efficiency and excellent surface finish standards while maintaining high operational stability.
• Laser treatment of cutting edges (ablation): DIA blade profiles are finished directly with a laser beam, allowing for edge radii of around 15 µm and guaranteeing a cutting plane free of microchip defects.
• Polished chip grooves and cutting zone: The smoothed back of the PCD diamond insert combined with capacious chip channels prevents the sticking of the workpiece and enhances rapid dust removal from the cutting zone.
• Low roughness of the shank: The surface of the shank with a roughness index of Ra ≤ 0.3 µm prevents the cutter from rotating in the tool holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to standard G2.5: Certified static-dynamic balancing in a demanding class G2.5 (according to ISO/EN) mitigates noise and reduces vibrations generated at high speeds.
• Regeneration capability: depending on the height of the diamond insert used: an insert of H = 2.0 mm allows for 2 times sharpening, an insert of H = 2.5 mm allows sharpening up to a maximum of 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow sharpening up to a maximum of 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm allow sharpening up to a maximum of 4–6 times.

Purpose and scope of application:

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 chipboards, and raw and laminated plywood.
