Two-flute VHM Spiral Mill 12x42 from the SB01 series – perfect edge quality and high machining performance

Index: SB01.12.042.090.12R

High-performance spiral mill made from a solid sintered carbide (VHM) monolith from the SB01 line, designed for tasks involving precise cutting, formatting, and finishing on overhead spindle milling machines and CNC centres. The tool features a two-flute spiral geometry in a positive 2 configuration, which forces effective chip removal upwards. The use of high-quality micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge's lifespan. The ground shank with a tolerance class of H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent finish standard of the machined material.

Design advantages and technical properties:

• Z2 finishing geometry (upward chip evacuation): Two cutting edges guarantee high cutting efficiency, ideal edge finish standard, and efficient upward chip removal.
• Monolith of Premium Sintered Carbide (VHM): The rigid, monolithic construction prevents deformation of the mill during operation under high force, allowing for narrow dimensional tolerances to be maintained.
• Possibility of applying PVD coating: The option of applying protective layers (e.g., TiSiN or PLATINIUM) allows for multiple extension of the edge lifespan, reduces friction, and protects against overheating.
• Low roughness of the gripping part: 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 wear on the cone in the spindle.
• Dynamic balancing to standard G2.5: Certified static-dynamic balancing in a high standard of G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds (up to 18,000 RPM).

Intended use and application range:

The tool is designed for cutting operations, contour milling, and finishing of edges.

It performs excellently in the machining of materials such as: soft and hardwood, raw MDF board, plywood, and raw particleboard.
