Single-Edge PCD Diamond Cutter DTB PRO – for finishing machining of panels and plywood

Index: DTB.20.045.20.SSR

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

Design advantages and technical properties:

• Increased axial angle and improved body construction: The increased axial inclination 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 processing of cutting edges (ablation): The profiles of the DIA blades are finished directly with a laser beam, allowing for edge radii at the level of 15 µm and guaranteeing a cutting plane free of micro-chipping.
• Polished chip grooves and entry zone: The smoothed back of the PCD diamond insert combined with spacious chip channels prevents chip adhesion and facilitates quick dust removal from the cutting zone.
• Low roughness of the gripping part: The surface of the shank in class H6 with a roughness indicator of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Sharpening specification (height of PCD insert): depending on the height of the diamond blade used: insert H = 2.0 mm allows for 2 sharpening cycles, insert H = 2.5 mm allows for 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 allow for sharpening up to 4–6 times.

Intended use and application range:

The tool is designed for cutting operations, peripheral milling, and mortising.

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