Two-flute VHM spiral end mill 4x15 from the SB01 series – perfect edge quality and high machining efficiency

Index: SB01.04.015.050.04L

High-performance spiral end mill made from a solid monolith of sintered carbide (VHM) from the SB01 line, designed for tasks related to precise cutting, shaping and finishing on overhead spindle mills and CNC centres. The tool uses a two-flute spiral geometry in a 2 configuration with a positive layout, which enforces effective chip removal upwards. The use of high-quality micro-grain carbide ensures high resistance to abrasive wear and significantly extends the life of the cutting edge. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent standard of finish for the machined material.

Design advantages and technical properties:

• Finishing geometry Z2 (upward chip removal): Two cutting edges ensure high cutting efficiency, ideal edge finish standard, and efficient upward chip removal.
• Premium sintered carbide monolith (VHM): Rigid, monolithic construction prevents deformation of the mill during operation under high forces, allowing for narrow dimensional tolerances to be maintained.
• Possibility of PVD coating application: The option of applying 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 surface of the shank with a roughness indicator of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and vibration generated at high speeds (up to 18,000 RPM).

Application and scope of use:

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

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