Spiral router bit Finishing VHM Z3 D12 I42 L90 S12 RH positive

VHM three-flute spiral end mill with chip breaker 12x42 mm from the SC03 series – maximum efficiency and high standard of machining

Index: SC03.12.042.090.12R

High-performance spiral end mill made from solid carbide (VHM) from the SC03 line, designed for efficient contour machining, cutting, and roughing-finishing operations on overhead spindle milling machines and CNC centres. The tool features a three-flute spiral geometry in a Z3R configuration with a positive arrangement, ensuring immediate removal of dust and chips upwards and maintaining perfect cleanliness of the lower edge. The blade breaker significantly reduces the mechanical loads on the system and crushes the cut material, enabling operation at higher feed rates without loss of stability. The ground shank with a tolerance class of H6 eliminates radial runout, protecting the spindle bearing system and ensuring impeccable detail quality.

Design advantages and technical properties:

• Chip breaker Z3R geometry (upward ejection): The arrangement of three cutting edges with a chip breaker reduces work resistance, streamlines the ejection of crushed material, and allows for fast feeding with ideal finishing of the lower edge.
• Premium solid carbide (VHM): The rigid, monolithic construction prevents deformation of the end mill under high force, allowing for precision cutting maintenance.
• Possibility of applying PVD coating: The option of applying protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of the edge's lifespan, 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 mill 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 the high-performance class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.

Intended use and scope of application:

The tool is intended for cutting operations, contour milling, pocketing, and semi-finishing and finishing machining.

It works excellently with materials such as soft and hard wood, raw MDF board, plywood, and raw particle board.
