PCD Straight Five-Blade Diamond Cutter

Index: DT5.20.022.20.0SR

Highly efficient five-blade diamond cutter from the DT5 series, equipped with polycrystalline diamond (PCD) blades. The tool is designed for extremely fast and precise cutting, shaping, flattening, grooving, and profiling of wood-based and composite materials on multi-axis CNC machining centres. The increased number of blades (Z5) allows for a significant boost in feed rates while maintaining perfect edge finish quality. The body made of cemented carbide with a hardness of 93.8 HRA or high-quality stainless steel guarantees maximum rigidity and dimensional stability under heavy loads. PCD blades arranged in negative or straight geometry eliminate the risk of chipping on laminate edges. The tool's design allows for multiple sharpening (2–4 times depending on the height of the diamond insert), which drastically reduces unit machining costs. The ground shank with an accuracy class of H6 protects against radial runout and safeguards the machine's drive system.

Key Technical Parameters and Properties:

• Five polycrystalline diamond (PCD) blades: Z5 geometry allows operation at ultra-high feed speeds while maintaining excellent smoothness of the machined material edges.
• Reinforced body construction: Made of cemented carbide (93.8 HRA) or stainless steel effectively dampens vibrations and ensures full operational stability.
• Multiple regeneration capability: PCD inserts with a height of H2.5 allow for 2–3 sharpening cycles, while a height of H3 enables 3–4 sharpening operations.
• Versatile machining capability: Suitable for efficient cutting, shaping, corner joints, grooving, and performing precise grooves.
• Optimised shank roughness: Low surface roughness of the shank (Ra ≤ 0.3 µm) prevents slipping in the holder and protects the spindle taper.
• Dynamic balance in class G2.5: Static-dynamic balancing according to ISO/EN standard (class G2.5) protects spindle bearings and ensures vibration-free operation at maximum speeds.
