VHM Spiral Milling Cutter Single Edge 3x12 from the SA01 series – perfect edge quality and high processing efficiency

Index: SA01.03.012.050.03R

A high-performance spiral milling cutter made from a solid sintered tungsten carbide (VHM) monolith from the SA01 line, designed for tasks related to precise cutting, formatting, and finishing on overhead milling machines and CNC centres. The tool features a uniform spiral geometry in a Z1 configuration with a positive angle, which enforces efficient 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 shaft with a tolerance class of H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent finishing standard of the work material.

Construction advantages and technical properties:

• Finishing geometry 1 (upward chip removal): The polished chip channel combined with a single cutting edge facilitates free evacuation of the material upwards while maintaining minimal cutting resistance.
• Premium (VHM) carbide monolith: The rigid, monolithic construction prevents deformation of the cutter during operation under high force, allowing for the maintenance of narrow dimensional tolerances.
• Possibility of applying PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for several times the lifespan of the edge, drastically reduces friction, and protects against overheating.
• Low roughness of the clamping part: The shaft surface with a roughness indicator of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of wearing the taper 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 minimizes vibrations generated at high speeds (18,000 – 24,000 RPM).

Intended use and scope of application:

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

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