PCD diamond router bit Z2+2 D20 I55 L113 S20 H2,5 LH

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

Index: DTN.20.055.20.0SL

The industrial diamond milling cutter from the DTN group has been created for specialised formatting operations, nesting and precise finishing of materials on overhead spindle milling machines and CNC centres. The tool uses a blade configuration Z2+2 -  polycrystalline diamond (PCD) tips distributed over four working 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 free dust removal, while the ground shank part in tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and guarantees an excellent edge condition after machining. 

Construction advantages and technical properties:

• Z2+2 geometry based on four spirals: A configuration providing high cutting performance and excellent surface finishing standard while maintaining high operational stability.
• Laser processing of cutting edges (ablation): The DIA blade profiles are finished directly with a laser beam, allowing edge radii of around 15 µm and ensuring a cutting plane free of micro-chips.
• Polished chip grooves and cutting entry area: The smoothed rear part of the PCD diamond insert combined with spacious chip channels prevents workpiece sticking and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The surface of the shank with a roughness indicator of Ra ≤ 0.3 µm secures the cutter against rotation in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balance in a stringent G2.5 class (according to ISO/EN) reduces noise and minimises vibrations generated at maximum speeds.
• Regrinding capability: depending on the height of the applied diamond tip: tip H = 2.0 mm allows for 2 regrinds, tip H = 2.5 mm allows for a maximum of 2–3 regrinds, variants H = 3.0 mm / H = 3.5 mm allow for a maximum of 3–4 regrinds, while tips H = 4.0 mm / H = 4.5 mm allow for a maximum of 4–6 regrinds.

Intended use and application range:

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

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