PCD diamond router bit Z2+2 D16 I45 L106 S20 H2,5 RH

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

Index: DTN.16.045.20.0SR

The industrial diamond milling cutter from the DTN group has been designed for specialised formatting, nesting, and precise finishing operations on overhead spindle milling machines and CNC centres. The tool uses a blade arrangement Z2+2 -  where polycrystalline diamond (PCD) inserts are distributed across four working spirals, supported by a tungsten carbide (HM) front insert. The cutter body is constructed from high-hardness steel (> 28 HRC). This design facilitates free dust removal, while the ground shank part, with a tight tolerance class of H6, eliminates radial runout, thus protecting the spindle bearings and ensuring excellent edge condition after machining. 

Construction advantages and technical properties:

• Z2+2 geometry based on four spirals: A configuration that delivers high cutting efficiency and an excellent finish on the material surface while maintaining great stability during operation.
• Laser processing of cutting edges (ablation): The 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 from micro-chipping.
• Polished chip grooves and cutting zone: The smoothed rear part of the PCD diamond insert combined with capacious chip channels prevents chip sticking and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The surface of the shank has a roughness index of Ra ≤ 0.3 µm to prevent the cutter from rotating in the holder and eliminate the risk of wear at the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in a stringent G2.5 class (according to ISO/EN) reduces noise and minimizes vibrations generated at the highest speeds.
• Regeneration potential: depending on the height of the diamond insert used: insert H = 2.0 mm allows for 2 sharpening sessions, insert H = 2.5 mm enables sharpening up to 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow for sharpening up to 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm enable sharpening up to 4–6 times.

Intended use and application range:

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

It is perfectly suited for machining materials such as: raw and laminated MDF board, raw and laminated particle board, and raw and laminated plywood.
