Spiral router bit Finishing VHM Z3 D12 I52 L100 S12 RH positive

3-flute VHM spiral cutter with chip breaker 12x52 mm from the SC03 series – maximum performance and high processing standards

Index: SC03.12.052.100.12R

A high-performance spiral cutter made from a solid monolith of sintered carbide (VHM) from the SC03 line, designed for efficient processing of formats, cutting, and roughing-finishing operations on overhead spindle milling machines and CNC centres. The tool features a three-flute spiral geometry in a Z3R positive configuration, ensuring immediate removal of dust and chips upwards as well as maintaining perfect cleanliness of the bottom edge. The chip breaker significantly reduces the mechanical loads on the system and crushes the material, allowing for operations at increased feed rates without loss of stability. The ground shank in tolerance class H6 eliminates radial run-out, protecting the spindle bearing system and ensuring impeccable detail quality.

Construction advantages and technical properties:

• Z3R chip breaker geometry (upward discharge): The arrangement of three cutting edges with a chip breaker reduces working resistance, optimises the discharge of crushed material and enables rapid feed with an ideal finish of the bottom edge.
• Monolith of Premium sintered carbide (VHM): The rigid, monolithic design prevents the cutter from deforming during high-force operations, allowing for cutting precision to be maintained.
• Possibility of applying PVD coating: 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 gripping part: The shank surface with a roughness index of Ra ≤ 0.3 µm prevents the cutter from spinning in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in an exceptionally high class G2.5 (according to ISO/EN) reduces noise and vibration generated at maximum speeds.

Intended use and application range:

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

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