PCD diamond router bit Z2+2 D12 I35 L99 S20 H2,5 RH

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

Index: DTN.12.035.20.0SR

The industrial diamond cutter from the DTN group has been designed for specialised formatting, nesting, and precise finishing operations of materials on overhead spindle milling machines and CNC centres. The tool uses a blade arrangement 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 free dust removal, while the ground shank part with a tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and guarantees excellent edge condition after machining. 

Construction advantages and technical properties:

• Z2+2 geometry based on four spirals: A configuration that provides high cutting efficiency and an excellent standard of surface finishing 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 about 15 µm and ensuring a cutting surface free of micro-chipping.
• Polished chip grooves and cutting zone: The smooth rear part of the PCD diamond insert combined with capacious chip channels prevents material adhesion and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm secures the cutter against rotating in the holder and eliminates the risk of wear at the cone in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the high class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Regeneration capability: Depending on the height of the diamond insert used: insert H = 2.0 mm allows for 2-fold sharpening, insert H = 2.5 mm enables sharpening a maximum of 2–3 times, options H = 3.0 mm / H = 3.5 mm allow for sharpening a maximum of 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm enable sharpening a maximum of 4–6 times.

Application and range of use:

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

It performs excellently in machining materials such as: raw and laminated MDF board, raw and laminated particle board, and raw and laminated plywood.
