Three-bladed diamond PCD cutter

Index: DT3.12.015.12.0DR

Industrial three-bladed diamond cutter from the DT3 series, equipped with polycrystalline diamond (PCD) blades. The tool is designed for high-performance cutting, shaping, aligning, grooving and rebating of wood-based and composite materials on CNC machining centres. The body made of sintered carbide with a hardness of 93.8 HRA or high-grade stainless steel ensures maximum rigidity and stability during machining. PCD blades set in negative or straight geometry provide a clean cutting edge and outstanding longevity. The tool design allows for multiple sharpening (2–4 times depending on the height of the diamond insert), significantly reducing operating costs. The ground shank in accuracy class H6 protects against radial runout.

Key technical parameters and properties:

• Polycrystalline diamond (PCD) blades: Three full PCD blades with negative or straight geometry guarantee outstanding durability and clean quality of the machined material edge.
• Reinforced body: Made of sintered carbide (93.8 HRA) or stainless steel eliminates vibrations and ensures high dimensional stability.
• Multiple sharpening capability: PCD inserts with a height of H2.5 allow for 2–3 sharpening cycles, and a height of H3 enables 3–4 regeneration operations.
• Operational versatility: Blade geometry adapted for cutting, shaping, angular joints, rebating, and grooving operations.
• Optimised grip roughness: Low surface roughness of the grip (Ra ≤ 0.3 µm) prevents slipping in the holder and protects the spindle cone.
• Dynamic balancing in class G2.5: Static-dynamic balancing in accordance with ISO/EN standards (class G2.5) protects spindle bearings and ensures vibration-free operation.

Application and material purpose:

Dedicated for mass machining on CNC machines and overhead milling machines in the furniture and carpentry industry.

Machined materials: Raw and laminated MDF, raw and laminated chipboard, cement-bonded particleboards, composites with glass and carbon fibre, Corian®, HPL, raw and laminated plywood, and aluminium.
