Spiral router bit Finishing VHM Z2 D6 I27 L70 S8 RH negative

Double-edged VHM spiralised cutter 6x27 mm from the SB51 series – ideal edge quality and high efficiency

Index: SB51.06.027.070.08R

This high-performance spiral cutter made of solid sintered carbide (VHM) from the SB51 line is designed for precise cutting, profiling, slotting, and grooving on overhead spindle milling machines and CNC centres. The tool uses a double-edged spiral geometry in a Z2 configuration with a negative layout, which forces effective chip removal downwards. The use of high-quality micro-grained carbide ensures high resistance to abrasive wear and significantly extends the life of the cutting edge. The ground shank with a tolerance class of H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent standard of finish on the machined material.

Design advantages and technical properties:

• Finishing geometry 2 (downward discharge): Two cutting edges directing the machined material downwards guarantee a clean upper edge of the raw material and effectively prevent lifting of veneer or laminate.
• Monolith of Premium sintered carbide (VHM): The rigid, monolithic structure prevents deformation of the cutter during intense work, allowing for narrow dimensional tolerances to be maintained.
• Option for PVD coating: The option of applying protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of the edge's life, reduces friction, and protects against overheating.
• Low roughness of the shank part: The shank surface with a roughness index of Ra ≤ 0.3 µm protects the cutter from spinning in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to 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 use and application range:

This tool is intended for operations such as cutting, peripheral milling, slotting, grooving, and finishing edge work.

It is excellent for machining materials such as: soft and hard wood, raw and laminated MDF board, raw and laminated plywood, as well as raw and laminated chipboard.
