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

Index: DTM.12.021.12.1DRP

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

Construction advantages and technical properties:

• Innovative DENSIMET® body: The use of high-density heavy metals precisely dampens vibrations during cutting, translating to longer durability of diamond blades and ideal quality of the machined surface.
• Z3+3 blade configuration on six spirals (positive/negative): Three solid polycrystalline diamond blades arranged on six spirals in a positive or negative configuration guarantee an excellent edge finishing standard of the board and the appropriate material ejection direction (upwards or downwards).
• PCD Front Plate: The front of the tool is equipped with a PCD plate facilitating free, smooth, and stable plunging of the cutter in the Z-axis during nesting operations.
• Laser Cutting Edge Treatment (ablation): The profiles of the DIA blades are finished directly with a laser beam, allowing for edge radii of approximately 15 µm and guaranteeing a cutting surface free of micro-chipping.
• Polished chip grooves and entry zone: The smoothed rear part of the PCD diamond plate combined with spacious chip channels prevents workpiece adhesion and improves the rapid removal of dust from the cutting zone.
• Low roughness of the shank: The shank surface with a roughness index of Ra ≤ 0.3 µm secures 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 strict G2.5 class (according to ISO/EN) reduces noise and decreases vibrations generated at the highest speeds.
• Regrindability: Depending on the height of the applied diamond blade: a plate H = 2.0 mm allows for 2-fold sharpening, a plate H = 2.5 mm accommodates 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 permit sharpening up to 4–6 times.

Purpose and application range:

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

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