Spiral router bit Finishing VHM Z2 D12 I35 L83 S12 LH positive

Two-flute spiral end mill 12x35 from the SB01 series – perfect edge quality and high machining performance

Index: SB01.12.035.083.12L

High-performance spiral end mill made from solid hard metal (VHM) from the SB01 line, designed for precision cutting, formatting, and finishing tasks on vertical milling machines and CNC centres. The tool utilises a two-flute spiral geometry in a 2 positive configuration, which promotes effective chip removal upwards. The use of high-quality micro-grain carbide ensures high wear resistance and significantly extends the lifespan of the cutting edge. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent standard of finish on the workpiece material.

Construction advantages and technical properties:

• Z2 finishing geometry (upward chip flow): Two cutting edges ensure high cutting performance, ideal edge finish, and efficient chip removal upwards.
• Premium sintered carbide monolith (VHM): Rigid, monolithic construction prevents the end mill from deforming during heavy-duty work, allowing for tight dimensional tolerances.
• PVD coating application option: The option of applying protective layers (e.g., TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• Low roughness of the clamping part: 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 spindle taper.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the high 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 works excellently for machining materials such as: soft and hardwood, raw MDF board, plywood, and raw particle board.
