Three-Blade PCD Diamond Cutter DTM DENSIMET® – for nesting, formatting and finishing processing

Index: DTM.12.025.12.5DRN

The industrial diamond cutter from the DTM DENSIMET® series is designed for high-efficiency nesting, cutting, and finishing processing on CNC centres and overhead spindle milling machines. The advanced design of the tool consists of three full blades made of polycrystalline diamond arranged on six spirals, complemented by a diamond cutting plate that enables efficient and stable axial penetration into the material. The body made of DENSIMET® (a heavy alloy with advanced vibration damping capabilities) provides high structural rigidity and reduces vibrations during machining. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent edge finish standard.

Design advantages and technical properties:

• Innovative DENSIMET® based body: The use of heavy metals with high density precisely dampens vibrations during cutting, which translates into longer durability of the diamond blades and ideal quality of the machined surface.
• Z3+3 blade arrangement on six spirals (positive/negative): Three full blades of polycrystalline diamond arranged on six spirals in a positive or negative configuration guarantee an excellent edge finish standard of the plate and the appropriate direction of chip ejection (upwards or downwards).
• PCD diamond cutting plate: The tool's front equipped with a PCD plate facilitates free, smooth, and stable insertion of the cutter in the Z-axis during nesting operations.
• Laser finishing of cutting edges (ablation): The profiles of the DIA blades are finished directly with a laser beam, achieving an edge radius of approximately 15 µm and guaranteeing a cutting surface free from micro-chipping.
• Polished chip grooves and cutting zone: The smoothed rear part of the PCD diamond plate combined with capacious chip channels prevents material sticking and facilitates quick removal of dust from the cutting zone.
• Low roughness of the gripping part: The shank surface with a roughness indicator of Ra ≤ 0.3 µm protects the cutter from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the strict class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Regeneration possibility: Depending on the blade height used: a plate H = 2.0 mm allows for 2-fold sharpening, a plate 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 plates H = 4.0 mm / H = 4.5 mm enable sharpening a maximum of 4–6 times.

Intended use and application scope:

The tool is intended for cutting, nesting, contour milling, and plunging operations.

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