Diamond milling cutter PCD single blade DTB PRO – for finishing machining of panels and plywood

Index: DTB.12.025.12.5SSR

The industrial diamond milling cutter from the DTB PRO series is designed for high-performance formatting and finishing milling on CNC centres and overhead milling machines. The tool features a single, full-size diamond blade (PCD) arranged on three spirals with an increased axial angle, supported by a cutting insert made of sintered carbide (HM). The durable body made of high-hardness steel (> 28 HRC) is characterised by a specially shaped geometry that facilitates chip and dust ejection. The ground shank in the strict accuracy class H6 minimises radial runout, protecting the spindle and ensuring trouble-free operation and a high edge finish standard.

Design advantages and technical properties:

• Increased axial angle and improved body construction: The increased axial tilt of the blades on the spiral, combined with the special geometry of the body, facilitates rapid chip removal, eliminating the phenomenon of re-grinding and overheating of the cutter.
• Laser treatment of cutting edges (ablation): The DIA blade profiles are finished directly with a laser beam, achieving edge radii of around 15 µm and guaranteeing a cutting plane free from micro-chips.
• Polished chip grooves and approach zone: The smoothed rear part of the PCD diamond insert, combined with spacious chip channels, prevents material stickiness and facilitates quick dust removal from the cutting zone.
• Low roughness of the holding part: The shank surface in class H6 with a roughness indicator of Ra ≤ 0.3 µm secures the cutter against rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to the G2.5 standard: Certified static-dynamic balancing in the rigorous class G2.5 (according to ISO/EN) reduces noise and lowers vibrations generated at high speeds.
• Sharpening specification (height of PCD insert): Depending on the height of the diamond blade used: an insert H = 2.0 mm allows for 2-times sharpening, an 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 operations, contour milling, and grooving.

It performs excellently in processing materials such as: raw and laminated MDF board, raw and laminated chipboard, and raw and laminated plywood.
