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

Index: DTN.18.045.20.0SR

The industrial diamond end mill from the DTN group has been designed for specialised formatting operations, nesting, and precise finishing of materials on overhead spindle milling machines and CNC centres. The tool uses a blade arrangement Z2+2 -  polycystalline diamond (PCD) inserts arranged on four cutting spirals, supported by a front insert made of cemented carbide (HM). The body of the mill consists of a hardened steel casing (> 28 HRC). This design facilitates the free removal of dust, while the ground shank in the tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and guarantees an excellent edge condition after machining. 

Design advantages and technical properties:

• Z2+2 geometry  based on four spirals: A system that provides high cutting efficiency and an excellent standard of surface finish while maintaining great operational stability.
• Laser-treated cutting edges (ablation): DIA blade profiles are finished directly by a laser beam, achieving edge radii of approximately 15 µm and ensuring a cutting surface free of micro-chipping.
• Polished chip flutes and cutting zone: The smoothed back of the PCD diamond insert combined with spacious chip channels prevents chip adhesion and enhances quick dust removal from the cutting area.
• Low roughness of the shank: The surface of the shank with a roughness index of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in a stringent class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Regenerable: depending on the height of the applied 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, options 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.

Intended use and scope of application:

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

It works excellently when machining materials such as: raw and laminated MDF board, raw and laminated particleboard, as well as raw and laminated plywood.
