Three-fluted roughing spiral end mill VHM from the SF51 series
Index: SF51.10.042.090.10R
Industrial spiral end mill made from solid carbide (VHM) from the SF51 series with a negative design (chip removal downwards). Designed for efficient rough machining, cutting, and slotting on CNC machining centres and overhead spindle milling machines. The left-hand helical flute (negative) presses the material against the work table, eliminating the risk of tear-out on the upper edge of the workpiece. Three spiral blades with a profiled chip breaker reduce cutting resistance, lower spindle load, and effectively dampen vibrations during intensive cutting. The ground shank in accuracy class H6 protects the drive system and ensures high process stability.
Key technical parameters and properties:
- Three-fluted roughing design Z3 (negative): Dedicated rough profile with downward chip removal presses the workpiece against the table and ensures a perfectly finished, clean upper edge.
- Premium class solid carbide (VHM): Rigid monolithic construction minimizes bending of the tool under load and guarantees high mechanical durability.
- Geometry with chip breaker: Divides the machined material into smaller pieces, reducing cutting resistance and stabilising operation.
- Optimised grip roughness: The surface of the shank features low roughness (Ra ≤ 0.3 µm), preventing slippage in the holder and protecting the spindle taper from wear.
- Dynamic balancing class G2.5: Static-dynamic balancing according to ISO/EN standard (class G2.5) eliminates vibrations at maximum rotational speeds.
