Spiral router bit Finishing VHM Z3 D12 I42 L90 S12 RH positive

VHM three-flute spiral mill 12x42 mm from the SC01 series – perfect edge quality and high machining performance

Index: SC01.12.042.090.12R

High-performance spiral mill made from solid sintered carbide (VHM) from the SC01 line, designed for tasks involving precise cutting, shaping, and finishing on overhead spindle milling machines and CNC centres. The tool utilises a three-flute spiral geometry in Z3 configuration with a positive rake angle, ensuring effective chip evacuation upwards. The use of high-quality micro grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge lifespan. The ground shank with a tolerance class of H6 eliminates radial run-out, protecting the spindle bearing system and guaranteeing an excellent finish standard for the machined material. 

Construction advantages and technical properties:

• Finishing geometry Z3 (upward chip removal): Three cutting edges guarantee very high cutting efficiency, allow for operation at higher feed rates, ensure an ideal edge finish standard, and facilitate efficient upward chip removal.
• Premium sintered carbide monolith (VHM): Rigid, monolithic construction prevents deformation of the mill under high forces, allowing for narrow dimensional tolerances to be maintained.
• Possibility of using a PVD coating: The option of applying protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of edge lifespan, reduces friction, and protects against overheating.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing at a high level of G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Intended use and application range:

The tool is designed for cutting, peripheral milling, and finishing edge operations.

It works perfectly for machining materials such as: soft and hard wood, raw MDF board, plywood, and raw particleboard.
