Spiral router bit Finishing VHM Z3 D18 I55 L110 S18 RH positive

VHM three-flute spiral end mill with chip breaker 18x55 mm from series SC03 – maximum efficiency and high standard of machining

Index: SC03.18.055.110.18R

High-performance spiral end mill made from solid sintered carbide (VHM) from the SC03 line, designed for efficient format 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 upward and maintaining perfect cleanliness of the lower edge. The chip breaker applied significantly reduces the mechanical loads on the system and shreds the material, allowing for operation at increased feed rates without loss of stability. The ground shank in H6 tolerance class eliminates radial runout, protecting the bearing system of the spindle and ensuring impeccable detail quality.

Design advantages and technical properties:

• Chip breaker geometry Z3R (upward ejection): The configuration of three cutting edges with a chip breaker reduces work resistance, improves the ejection of shredded material, and enables fast feed with ideal finishing of the lower edge.
• Monolith made of premium sintered carbide (VHM): The rigid, monolithic structure prevents the deformation of the mill during operation under high forces, allowing for machining precision.
• Possibility of applying PVD coating: The option of applying protective coatings (e.g., TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• Low roughness of the clamping part: 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 wearing the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the high class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.

Intended use and application range:

The tool is intended for cutting operations, contour milling, grooving, and medium roughing and finishing machining.

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