PCD diamond router bit Z2+2 D20 I65 L129 S20 H2,5 RH

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

Index: DTN.20.065.20.0SR

The industrial diamond milling 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 features a blade system Z2+2 -  with polycrystalline diamond (PCD) inserts arranged on four cutting spirals, supported by a front insert made of cemented carbide (HM). The cutter's body is made of high-hardness steel (> 28 HRC). This construction facilitates the free removal of dust, while the ground shank part in a tight tolerance class H6 eliminates radial runout, protecting the spindle bearings and guaranteeing excellent edge condition after processing. 

Construction advantages and technical properties:

• Z2+2 geometry  based on four spirals: A configuration providing high cutting efficiency and excellent material surface finishing standard 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 at the level of 15 µm and ensuring a cutting surface free of micro-chipping.
• Polished chip grooves and the cutting area: The smoothed back part of the PCD diamond insert combined with capacious chip channels prevents material adhesion and improves rapid dust removal from the cutting area.
• Low roughness of the shank: The surface of the shank with roughness index Ra ≤ 0.3 µm protects 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 the stringent G2.5 class (according to ISO/EN) reduces noise and vibrations generated at maximum speeds.
• Sharpening capability: depending on the height of the diamond insert used: insert H = 2.0 mm allows for 2 times sharpening, insert H = 2.5 mm enables sharpening a maximum of 2–3 times, variations 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 allow for sharpening a maximum of 4–6 times.

Purpose and areas of application:

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

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