Spiral router bit Finishing VHM Z3 D20 I70 L120 S20 RH positive

Three-flute VHM spiral end mill 20x70 mm from the SC01 series – perfect edge quality and high machining efficiency

Index: SC01.20.070.120.20R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SC01 line, intended for precision cutting, formatting, and finishing tasks on overhead spindle milling machines and CNC centres. The tool utilises a three-flute spiral geometry in a Z3 positive configuration, which promotes effective chip removal upwards. The use of high-quality micrograin carbide ensures high wear resistance and significantly extends the service life of the cutting edge. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle's bearing assembly and ensuring an excellent standard of finish on the machined material. 

Construction advantages and technical properties:

• Finishing geometry Z3 (upward chip ejection): Three cutting edges guarantee very high cutting efficiency, allow for operation at higher feed speeds, provide an ideal standard of edge finishing, and ensure efficient upward chip removal.
• Monolith made of Premium sintered carbide (VHM): The rigid, monolithic design prevents deformation of the mill during operation under high force, allowing for tight dimensional tolerances to be maintained.
• Capability for PVD coating application: The option to apply protective coatings (e.g., TiSiN or PLATINIUM) allows for significantly extended tool 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 mill 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 stringent G2.5 class (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds (up to 18,000 RPM).

Purpose and range of application:

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

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