PCD Diamond Cutter from the DTN Z2+2 Series – for Finishing, Nesting, and Formatting Operations

Index: DTN.12.030.12.5SR

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 cutting edge configuration Z2+2 -  with polycrystalline diamond (PCD) inserts arranged on four cutting spirals, supported by a front plate made of sintered carbide (HM). The cutter's shaft consists of a body made of high-hardness steel (> 28 HRC). This design facilitates the free removal of dust, while the ground clamping part with a tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and ensures excellent edge condition after machining. 

Structural Advantages and Technical Properties:

• Z2+2 Geometry based on four spirals: A configuration that provides high cutting efficiency and an excellent finish standard while maintaining great operational stability.
• Laser edge treatment (ablation): The DIA cutting edge profiles are finished directly with a laser beam, allowing edge radii of around 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished cutting grooves and chip-collecting area: The smoothed rear part of the PCD diamond insert combined with large chip channels prevents workpiece sticking and facilitates quick removal of dust from the cutting area.
• Low roughness of the clamping part: The shank surface 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 to G2.5 standard: Certified static-dynamic balancing in a high class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Regeneration possibility: Depending on the height of the diamond insert used: insert H = 2.0 mm allows for 2 sharpening processes, insert H = 2.5 mm permits 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 Scope of Application:

The tool is designed 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.
