Spiral router bit Finishing VHM Z1 D5 I17 L50 S5 RH positive

Single-flute VHM spiral end mill 5x17 from the SA01 series – perfect edge quality and high machining performance

Index: SA01.05.017.050.05R

A high-performance spiral end mill made from solid sintered carbide (VHM) from the SA01 line, designed for tasks involving precise cutting, shaping, and finishing on vertical milling machines and CNC centres. The tool employs a uniform spiral geometry in Z1 configuration with a positive arrangement, which promotes effective chip removal upwards. The use of high-quality micrograin carbide ensures high wear resistance and significantly extends the durability of the cutting edge. The ground shank in tolerance class 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 1 (upward chip discharge): Polished chip flutes combined with a single cutting edge facilitate free evacuation of chips upwards while maintaining minimal cutting resistance.
• Premium sintered carbide (VHM) monolith: A rigid, monolithic construction prevents deformation of the mill during heavy force application, allowing for the maintenance of tight dimensional tolerances.
• PVD coating application capability: The option of applying protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of edge life, drastically reduces friction, and protects against overheating.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm protects the mill 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 an exacting G2.5 class (according to ISO/EN) reduces noise and vibration generated at high speeds (18,000 – 24,000 RPM).

Intended use and application range:

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

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