PCD diamond router bit Z2+2 D12 I35 L79 S12 H2,5 RH

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

Index: DTN.12.035.12.0SR

The industrial diamond milling cutter from the DTN group has been designed for specialised formatting operations, nesting and precise finishing of materials on overhead spindle milling machines and CNC centres. The tool utilises a blade system Z2+2 -  with polycrystalline diamond (PCD) inserts arranged on four working spirals, supported by a tungsten carbide (HM) frontal insert. The cutter's body is made of high-hardness steel (> 28 HRC). This construction facilitates the free removal of dust, while the ground shank in a tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and guarantees excellent edge condition after machining. 

Design 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 great work stability.
• Laser edge treatment (ablation): DIA blade profiles are finished directly with a laser beam, allowing for edge radii of around 15 µm and ensuring a cutting plane free from microchipping.
• Polished chip grooves and clearance zone: The smoothed rear part of the PCD insert combined with spacious chip channels prevents the sticking of cut material and facilitates quick removal of dust from the cutting area.
• Low roughness of the shank: The shank 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 conical interface in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) minimises noise and reduces vibrations generated at high speeds.
• Regeneration capability: Depending on the height of the applied diamond blade: the H = 2.0 mm insert allows for 2 cuts, the H = 2.5 mm insert permits a maximum of 2–3 cuts, while H = 3.0 mm / H = 3.5 mm variants allow for a maximum of 3–4 cuts, and blades H = 4.0 mm / H = 4.5 mm enable a maximum of 4–6 cuts.

Purpose and application range:

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

It performs excellently in the machining of materials such as raw and laminated MDF boards, raw and laminated chipboards, and raw and laminated plywood.
