Spiral router bit Finishing VHM Z2 D6 I22 L70 S6 RH negative TiSiN

VHM twin-blade spiral cutter 6x22 mm from the SB51 series – ideal edge quality and high performance

Index: SB51.06.022.070.06TR

High-performance spiral cutter made from a solid sintered carbide (VHM) monolith from the SB51 line, intended for precision cutting, shaping, grooving, and notching on overhead spindle milling machines and CNC centres. The tool features a twin-blade spiral geometry in a Z2 configuration with a negative arrangement, which enforces efficient chip removal downwards. The use of high-quality micro-grain carbide ensures high wear resistance and significantly prolongs the cutting edge lifespan. The ground shank in tolerance class H6 eliminates radial run-out, protecting the spindle bearing assembly and guaranteeing an excellent finish standard for the machined material.

Design advantages and technical properties:

• Finishing geometry 2 (downward discharge): Two cutting edges directing the chips downwards guarantee a clean upper edge of the processed material and effectively prevent the lifting of veneer or laminate.
• Premium sintered carbide monolith (VHM): The rigid, monolithic construction prevents deformation of the cutter under high force, allowing for narrow dimensional tolerances.
• Possibility of applying a PVD coating: The option of applying protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• Low roughness of the clamping part: The shank surface with a roughness indicator of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of wear at the spindle taper.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Intended purpose and application range:

The tool is intended for cutting, peripheral milling, grooving, notching, and finishing edge operations.

It performs excellently when machining materials such as: soft and hard wood, raw and laminated MDF board, raw and laminated plywood, and raw and laminated particle board.
