Spiral router bit Finishing VHM Z3 D20 I102 L165 S20 RH positive

Three-flute VHM spiral end mill with chip breaker 20x102 mm from the SC03 series – maximum efficiency and high processing standard

Index: SC03.20.102.165.20R

High-performance spiral end mill made from a solid monolith of sintered carbide (VHM) from the SC03 line, designed for efficient formatting, cutting, and roughing-finishing operations on overhead spindle milling machines and CNC centres. The tool uses a three-flute spiral geometry in the Z3R positive configuration, which guarantees immediate removal of dust and chips upwards and maintains perfect cleanliness of the bottom edge. The applied chip breaker significantly reduces mechanical load on the system and crushes the output, allowing for operation with an increased feed rate 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 geometry Z3R (upward ejection): The arrangement of three cutting edges with a chip breaker reduces working resistance, enhances the ejection of crushed output, and allows for fast feed with ideal finishing of the bottom edge.
• Monolith of Premium sintered carbide (VHM): The rigid, monolithic structure prevents deformation of the mill during heavy-duty work, allowing for precise cutting performance.
• Possibility of PVD coating application: The option to apply protective layers (including 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 a stringent G2.5 class (according to ISO/EN) reduces noise and vibration generated at high speeds.

Intended use and scope of application:

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

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