PCD Diamond Milling Cutter from the DTN Z2+2 Series – for finishing, nesting, and formatting

Index: DTN.12.035.12.5SR

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 -  with polycrystalline diamond (PCD) inserts arranged on four cutting spirals, supported by a cutting insert made of cemented carbide (HM). The body of the cutter is made of high-hardness steel (> 28 HRC). This construction facilitates efficient dust removal, while the ground shank in a tight tolerance class H6 minimises radial runout, protecting the spindle bearings and ensuring excellent edge conditions after machining. 

Design Advantages and Technical Properties:

• Z2+2 Geometry based on four spirals: A configuration that provides high cutting efficiency and an excellent finish standard of the material surface, maintaining great operational stability.
• Laser processing of cutting edges (ablation): DIA blade profiles are finished directly with a laser beam, allowing edge radii as small as 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished chip grooves and entry zone: The smooth rear part of the PCD diamond insert combined with spacious chip channels prevents workpiece sticking and improves rapid dust removal from the cutting zone.
• Low roughness of the shank: The surface of the shank with a roughness index of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the high G2.5 class (according to ISO/EN) reduces noise and diminishes vibrations generated at high speeds.
• Regrinding capability: depending on the height of the used diamond insert: insert H = 2.0 mm allows for 2-times sharpening, insert H = 2.5 mm enables sharpening a maximum of 2–3 times, variants 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 permit sharpening a maximum of 4–6 times.

Intended Use and Application Range:

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

It performs excellently in machining materials such as: raw and laminated MDF boards, raw and laminated chipboards, as well as raw and laminated plywood.
