Double-edged VHM spiral end mill 3x12 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.03.012.060.06R

High-performance spiral end mill made from a solid monolith of sintered carbide (VHM) from the SB01 line, intended for tasks involving precise cutting, formatting, and finishing on router mills and CNC centres. The tool uses a double-edged spiral geometry in a 2 configuration with a positive layout, forcing effective chip removal upwards. The application of high-quality micro-grain carbide ensures high wear resistance and significantly extends the lifespan of the cutting edge. The ground shank with a tolerance class of H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent finish standard for the machined material.

Construction advantages and technical properties:

• Z2 finishing geometry (upward chip removal): Two cutting edges ensure high cutting efficiency, ideal edge finish standard, and efficient upward chip removal.
• Premium sintered carbide monolith (VHM): Rigid, monolithic construction prevents deformation of the mill during operation under high force, allowing for narrow dimensional tolerances to be maintained.
• Possibility of applying PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of edge lifespan, reduces friction, and protects against overheating.
• Low roughness of the grip part: The shank surface with a roughness value 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 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, contour milling, and edge finishing operations.

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