PCD diamond router bit Z1+1 D20 I55 L113 S20 H2,5 LH

Diamond PCD milling cutter from the DTA series for finishing machining of boards and plywood

Index: DTA.20.055.20.0SL

The industrial diamond milling cutter of the DTA series is designed for formatting and finishing machining on CNC centres and overhead spindle milling machines. The tool's construction is based on a diamond blade arranged on three spirals and a front plate made of sintered carbide (HM). The blades are mounted on a body made of high-hardness steel (> 28 HRC) or – in selected variants – from sintered carbide monolith (HM). The thoughtful geometry of the cutting edges ensures stable guidance in the processed material, while the high accuracy class of the grip H6 limits radial runout, protecting the spindle and guaranteeing excellent edge finish quality. The tool is offered in right and left rotations.

Design advantages and technical properties:

• Laser processing of cutting edges (ablation): The profiles of the DIA blades are finished directly by a laser beam, allowing edge radii to be achieved at the level of 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished chip grooves and leading edge zone: The smoothed back part of the PCD diamond plate combined with spacious chip channels prevents material sticking and facilitates quick dust removal from the cutting zone.
• Low roughness of the gripping part: The shank surface with a roughness index of Ra ≤ 0.3 µm protects the cutter against rotation in the holder and eliminates the risk of wear on the taper in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and diminishes vibrations generated at maximum speeds.
• Sharpening specification (height of PCD plate): Depending on the height of the diamond blade used: plate H = 2.0 mm allows for 2-time sharpening, plate H = 2.5 mm enables sharpening up to 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow for sharpening up to 3–4 times, while plates H = 4.0 mm / H = 4.5 mm enable sharpening up to 4–6 times.

Intended use and scope of application:

The tool is intended for cutting operations, peripheral milling, and slotting.

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