VHM single-flute spiral end mill 8x22 from the SA01 series – perfect edge quality and high machining efficiency

Index: SA01.08.022.070.08R

A high-performance spiral end mill made from solid sintered carbide (VHM) from the SA01 line, intended for tasks related to precise cutting, shaping, and finishing on overhead spindle milling machines and CNC centres. The tool features a uniform spiral geometry in configuration Z1 with a positive angle, which facilitates efficient chip removal upwards. The use of high-grade micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge's durability. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and ensuring an excellent standard of finish on the workpiece material.

Structural advantages and technical properties:

• Finishing geometry 1 (upward chip evacuation): A polished chip flute combined with a single cutting edge facilitates free upward evacuation of the chips while maintaining minimal cutting resistance.
• Premium sintered carbide monolith (VHM): The rigid, monolithic construction prevents deformation of the end mill during operation under high forces, allowing for the maintenance of narrow dimensional tolerances.
• Possibility of PVD coating application: The option to apply protective coatings (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 prevents the end mill from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing in standard G2.5: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and vibration generated at high speeds (18,000 – 24,000 RPM).

Purpose and range of application:

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

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