Spiral router bit Finishing VHM Z2 D20 I60 L120 S20 RH positive

VHM spiral end mill two-flute 20x60 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.20.060.120.20R

High-performance spiral end mill made from solid carbide (VHM) from the SB01 line, designed for tasks related to precise cutting, contouring, and finishing on overhead spindle milling machines and CNC centres. The tool features a two-flute spiral geometry in a 2 configuration with a positive arrangement, 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 durability. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle's bearing system and guaranteeing an excellent finishing standard for the machined material.

Design advantages and technical properties:

• Finishing geometry Z2 (upward chip removal): Two cutting edges guarantee high cutting efficiency, ideal edge finishing standard, and efficient upward chip removal.
• Premium sintered carbide monolith (VHM): Sturdy, monolithic construction prevents the tool from deforming 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 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 tool from rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in an extremely tight class 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 designed for cutting operations, contour milling, and finishing edge machining.

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