PCD diamond router bit Z2+2 D18 I35 L94 S20 H2,5 LH

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

Index: DTN.18.035.20.0SL

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

Structural advantages and technical properties:

• Z2+2 geometry  based on four spirals: A configuration that provides high cutting performance and excellent surface finishing of the material 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 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 deep chip channels prevents material from 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 tool holder and eliminate the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static and dynamic balancing in the high-end class G2.5 (according to ISO/EN) reduces noise and vibration generated at high speeds.
• Re-grinding capability: depending on the height of the used diamond insert: insert H = 2.0 mm allows 2-times sharpening, insert H = 2.5 mm allows sharpening up to 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow sharpening up to 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm allow sharpening up to 4–6 times.

Intended use and application range:

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

It works perfectly for processing materials such as raw and laminated MDF board, raw and laminated particle board, and raw and laminated plywood.
