Three-edged PCD diamond cutter DTE DENSIMET® – for nesting, finishing and flattening

Index: DTE.12.025.12.1DR

The industrial diamond cutter of the DTE DENSIMET® series is designed for efficient nesting, cutting, peripheral milling, and flattening of surfaces on CNC centres and overhead routers. The tool's construction features three solid edges made of polycrystalline diamond (H3) arranged on three spirals, complemented by a diamond front insert that allows for efficient and stable axial penetration into the material. The body, made of DENSIMET® material (a heavy alloy with an extremely high density and vibration-damping capability), provides outstanding rigidity, vibration reduction, and an excellent edge finishing standard.

Design advantages and technical properties:

• Innovative DENSIMET® body: The use of high-density heavy metals effectively dampens vibrations during cutting, translating into longer durability of diamond edges and ideal quality of the machined surface.
• Z3+1 positive or negative blade geometry: Three solid cutting edges made of polycrystalline diamond on three spirals allow for adapting the proper chip removal direction (positive/negative) depending on the material specifics and edge requirements.
• PCD front insert: The tool's front equipped with a PCD insert facilitates free, smooth, and stable penetration of the cutter in the Z-axis during nesting and drilling operations.
• Laser edge treatment (ablation): DIA blade profiles are finished directly with a laser beam, achieving edge radii around 15 µm and ensuring a cutting surface free of micro-chipping.
• Polished chip grooves and entry zone: The smoothed back part of the PCD diamond insert combined with capacious chip channels prevents material sticking and facilitates rapid dust removal from the cutting zone.
• Low roughness of the gripping part: The shank surface with a roughness index of Ra ≤ 0.3 µm secures the cutter against rotation in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the high standard of G2.5 (according to ISO/EN) eliminates noise and reduces vibrations generated at maximum speeds.
• Regeneration capability: depending on the height of the applied diamond edge: insert H = 2.0 mm allows for 2 times sharpening, 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 permit sharpening up to 4–6 times.

Purpose and scope of use:

The tool is intended for cutting, nesting, peripheral milling, and flattening (planning) operations.

It works excellently for processing materials such as: raw and laminated MDF board, raw and laminated particle board, as well as raw and laminated plywood.
