Spiral router bit Finishing VHM Z2 D4 I27 L70 S6 RH positive

Two-flute spiral end mill 4x27 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.04.027.070.06R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SB01 line, designed for tasks involving precise cutting, shaping, and finishing on top spindle milling machines and CNC machining centres. The tool features a two-flute spiral geometry in configuration 2 with a positive layout, which promotes 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 lifespan. The ground shank in tolerance class H6 compensates for radial runout, protecting the spindle bearing assembly and guaranteeing an excellent standard of surface finish on the machined material.

Construction advantages and technical properties:

• Finishing geometry Z2 (upward chip removal): Two cutting edges ensure high cutting efficiency, ideal edge finish, and efficient upward chip removal.
• Premium sintered carbide monolith (VHM): Rigid, monolithic construction prevents deformation of the end mill during operation under high force, allowing for tightly maintained dimensional tolerances.
• Possibility of PVD coating application: The option to apply protective coatings (e.g., 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 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 the stringent G2.5 class (according to ISO/EN) mitigates noise and reduces vibrations generated at high speeds (up to 18,000 RPM).

Intended use and field of application:

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

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