2-flute spiral end mill 3x12 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.03.012.050.03R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SB01 line, intended for tasks involving precise cutting, shaping, and finishing on vertical spindle milling machines and CNC centres. The tool features a 2-flute spiral geometry in a positive 2 configuration, which facilitates effective chip removal upwards. The use of high-quality micrograin carbide ensures high wear resistance and significantly extends the tool life of the cutting edge. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent finishing standard for the machined material.

Design advantages and technical properties:

• Finishing geometry Z2 (upward discharge): Two cutting edges guarantee high cutting performance, ideal edge finishing standard, and efficient chip removal upwards.
• Premium sintered carbide monolith (VHM): The rigid, monolithic construction prevents deformation of the mill when working under high forces, allowing for tight dimensional tolerances to be maintained.
• Possibility of applying a PVD coating: The option of applying protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of cutting edge 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 mill from rotating in the holder and eliminates the risk of wear on the taper in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the high standard of G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds (up to 18,000 RPM).

Intended use and application range:

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

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