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

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

Index: SC01.20.070.120.20L

High-performance spiral end mill made from solid sintered carbide (VHM) from the SC01 line, designed for tasks involving precise cutting, shaping and finishing on overhead spindle milling machines and CNC centres. The tool uses a three-flute spiral geometry in a Z3 configuration with a positive rake, which forces efficient chip removal upwards. The use of high-quality micrograin carbide ensures high resistance to abrasive wear and significantly extends the tool life 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 standard of finish on the workpiece material. 

Design advantages and technical properties:

• Finishing geometry Z3 (upward chip evacuation): Three cutting edges guarantee very high cutting efficiency, allow for operation at higher feed speeds, provide an ideal standard of edge finish, and facilitate efficient upward chip removal.
• Premium sintered carbide monolith (VHM): The rigid, monolithic construction prevents deformation of the end mill during operation under high forces, allowing for the maintenance of tight dimensional tolerances.
• Possibility of applying a PVD coating: The option of applying 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 surface of the shank with a roughness index of Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of wear to the taper in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in a stringent G2.5 class (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 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 particleboard.
