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

Index: SB01.03.012.060.06L

High-performance spiral end mill made from solid sintered carbide (VHM) from the SB01 line, designed for tasks involving precise cutting, profiling, and finishing on routed and CNC machining centres. The tool employs a two-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 life. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent finishing standard of the machined material.

Structural advantages and technical properties:

• Finishing geometry Z2 (upward chip ejection): Two cutting edges ensure high cutting efficiency, ideal edge finishing standard, and efficient upward chip removal.
• Premium (VHM) sintered carbide monolith: The rigid, monolithic structure prevents warping of the end mill during operation under high forces, allowing for tight dimensional tolerances to be maintained.
• PVD coating application option: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of 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 prevents the end 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 the strict G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Intended use and scope of application:

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

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