Spiral router bit Finishing VHM Z3 D20 I60 L120 S20 LH positive

VHM three-flute spiral end mill 20x60 mm from the SC01 series – perfect edge quality and high machining efficiency

Index: SC01.20.060.120.20L

A 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 vertical milling machines and CNC machining centres. The tool features a three-flute spiral geometry in a Z3 configuration with a positive layout, which forces efficient chip removal upwards. The use of high-grade micro-grain carbide ensures high resistance to abrasive wear and significantly extends cutting edge durability. 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 machined material. 

Structural advantages and technical properties:

• Finishing geometry Z3 (upward chip removal): Three cutting edges guarantee very high cutting performance, allow operation at higher feed speeds, ensure an ideal edge finish standard, 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 tight dimensional tolerances to be maintained.
• Possibility of applying PVD coating: 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 surface of the shank with a roughness index of Ra ≤ 0.3 µm prevents the end mill from rotating in the collet and eliminates the risk of wear at the taper in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the strict G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Purpose and scope of application:

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

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