Two-flute VHM spiral cutter 4x15 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.04.015.060.06L

High-performance spiral cutter made from solid sintered carbide (VHM) from the SB01 line, designed for tasks involving precise cutting, formatting, and finishing on vertical milling machines and CNC centres. The tool features a two-flute spiral geometry in a 2 configuration with a positive layout, which enforces effective chip removal upwards. The use of high-quality micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge durability. The ground shank in tolerance class H6 reduces radial runout, protecting the spindle bearing assembly and guaranteeing an excellent standard of finish on the machined material.

Structural advantages and technical properties:

• Z2 finishing geometry (upward chip removal): Two cutting edges ensure high cutting efficiency, ideal edge finish standard, and effective upward chip removal.
• Premium sintered carbide monolith (VHM): The rigid, monolithic structure prevents the cutter from deforming during operation under high forces, allowing for tight dimensional tolerances.
• Possibility of applying PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of the edge lifespan, 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 cutter from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the high class G2.5 (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 operations, contour milling, and finishing edge processing.

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