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

VHM three-flute roughing spiral end mill 12x42 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.12.042.090.12R

Industrial spiral end mill made from solid carbide (VHM) from the SF01 line, designed for intensive cutting, preliminary shaping, and efficient rough machining on vertical milling machines and CNC centres. The tool features a three-flute spiral geometry with a roughing profile in a Z3 configuration with a positive rake, ensuring swift chip removal upwards and a clean finish on the lower edge of the workpiece. The specially designed roughing teeth effectively break the material into smaller particles, reducing cutting forces and relieving the machine drive system. The ground shank with a tolerance class of H6 minimizes radial runout, protecting the spindle and ensuring a high level of stability during operation.

Design advantages and technical properties:

• Z3 roughing design (upward chip removal): Three cutting edges with a roughing profile reduce operational resistance, efficiently remove chips upwards, and allow for machining at high feed rates while maintaining a clean lower edge.
• Premium solid carbide (VHM) construction: The rigid monolithic construction limits tool deflection under load and ensures high dimensional precision.
• PVD coating application option: The option to apply protective layers (e.g., TiSiN or PLATINIUM) allows for several times extended tool life, 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 end mill from rotating in the holder and eliminates the risk of wear on the spindle nose.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and vibration generated at high speeds.

Intended use and range of application:

The tool is intended for cutting operations, preliminary shaping, and efficient rough machining.

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