VHM two-flute spiral end mill 6x27 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.06.027.070.08L

High-performance spiral end mill made from solid hard metal (VHM) from the SB01 line, intended for tasks related to precise cutting, shaping, and finishing on a router and CNC machining centres. The tool uses a two-flute spiral geometry in 2 configuration with a positive arrangement, which forces efficient chip removal upwards. The use of high-quality micrograin carbide ensures high resistance to abrasive wear and significantly extends the cutting edge lifespan. The ground shank with a tolerance class of H6 reduces radial runout, protecting the spindle bearing system and guaranteeing an excellent finish standard for the machined material.

Design advantages and technical properties:

• Finishing geometry Z2 (upward chip removal): Two cutting edges ensure high cutting efficiency, an ideal edge finish standard, and efficient upward chip removal.
• Premium sintered carbide monolith (VHM): The rigid, monolithic construction prevents deformation of the mill during operation under high forces, allowing for tight dimensional tolerances.
• Possibility of applying PVD coating: The option to apply protective coatings (including TiSiN or PLATINIUM) allows for multiple extensions of the edge life, 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 rotating 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 advanced class 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 intended for cutting, contour milling, and finishing edge operations.

It is particularly effective in machining materials such as: soft and hard wood, untreated MDF board, plywood, and untreated particle board.
