Twin-flute solid carbide spiral end mill 3x22 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.03.022.070.06R

High-performance spiral end mill made from solid carbide (VHM) from the SB01 line, intended for tasks related to precision cutting, shaping, and finishing on vertical milling machines and CNC centres. The tool utilises a twin-flute spiral geometry in a 2 configuration with a positive layout, 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 service life. The ground shank in the tolerance class H6 minimises radial runout, protecting the spindle bearing system and guaranteeing an excellent finish standard of the machined material.

Design advantages and technical properties:

• Finishing geometry Z2 (upward chip eject): Two cutting edges guarantee high cutting efficiency, an ideal finish standard of the edge, and efficient upward removal of chips.
• Premium solid carbide (VHM) monolith: The rigid, monolithic construction prevents distortion of the end mill during work under high force, allowing for narrow dimensional tolerances to be maintained.
• Possibility of PVD coating application: The option to apply protective layers (including TiSiN or PLATINUM) allows for multiple extensions of the edge's life, reduces friction, and protects against overheating.
• Low roughness of the shank: The shank surface with a roughness index of Ra ≤ 0.3 µm prevents the end mill from rotating in the tool holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) eliminates noise and reduces vibrations generated at high speeds (up to 18,000 RPM).

Intended use and application range:

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

It performs excellently in the processing of materials such as soft and hard wood, raw MDF board, plywood, and raw particle board.
