VHM three-flute spiral end mill 12x42 mm from the SC01 series – perfect edge quality and high machining efficiency

Index: SC01.12.042.090.12L

High-performance spiral end mill made from a solid sintered carbide (VHM) monolith from the SC01 line, designed for tasks related to precise cutting, shaping, and finishing on overhead spindle milling machines and CNC centres. The tool features a three-flute spiral geometry in a Z3 configuration with a positive arrangement, which enforces effective chip removal upwards. The use of high-quality micro-grain carbide provides high wear resistance and significantly extends the cutting edge's durability. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing assembly and ensuring an excellent finish standard on the machined material. 

Design advantages and technical properties:

• Finishing geometry Z3 (upward chip evacuation): Three cutting edges ensure very high cutting efficiency, allow operation at higher feed speeds, provide an ideal edge finish standard, and facilitate efficient upward chip removal.
• Premium sintered carbide monolith (VHM): The rigid, monolithic structure prevents deformation of the mill during operation under high forces, allowing narrow dimensional tolerances 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 shank: The shaft surface with a roughness indicator of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of the cone wearing in the spindle.
• Dynamic balancing to G2.5 standards: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at the highest speeds (up to 18,000 RPM).

Application and range of use:

The tool is designed for cutting, contour milling, and edge finishing operations.

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