Spiral router bit Finishing VHM Z3 D8 I32 L72 S8 RH positive

VHM three-edge spiral cutter with chip breaker 8x32 mm from the SC03 series – maximum efficiency and high processing standards

Index: SC03.08.032.072.08R

High-performance spiral cutter made from a solid monolith of sintered carbide (VHM) from the SC03 line, intended for efficient format processing, cutting, and finishing and roughing operations on overhead spindle milling machines and CNC centres. The tool utilises a three-edge spiral geometry in the Z3R configuration with a positive arrangement, which ensures the immediate removal of dust and chips upwards and maintains the perfect cleanliness of the lower edge. The applied chip breaker noticeably reduces the mechanical load on the system and crushes the produced material, allowing for operation at an increased feed rate 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.

Design advantages and technical properties:

• Geometry with Z3R chip breaker (upward chip removal): The arrangement of three cutting edges with the chip breaker reduces cutting resistance, streamlines the removal of crushed material, and allows for quick feed with an ideal finish of the lower edge.
• Monolith of Premium sintered carbide (VHM): The rigid, monolithic construction prevents deformation of the cutter during operation under high loads, allowing for the preservation of cutting precision.
• 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 clamping part: The surface of the shank with a roughness index of Ra ≤ 0.3 µm secures the cutter against rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the high-class G2.5 (according to ISO/EN) eliminates noise and reduces vibrations generated at maximum speeds.

Intended use and application range:

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

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