VHM finishing spiral mill Z2 D3 I12 L50 S3 RH negative

Spiral end mill VHM two-flute 3x12 mm from the SB51 series – ideal edge quality and high performance

Index: SB51.03.012.050.03R

High-performance spiral end mill made from solid carbide (VHM) from the SB51 line, intended for precise cutting, profiling, grooving, and slotting on milling machines and CNC centres. The tool features a two-flute spiral geometry in a Z2 configuration with a negative arrangement, which ensures effective chip removal downwards. The use of high-quality micro-grain carbide provides high resistance to abrasive wear and significantly extends the cutting edge durability. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent finishing standard of the machined material.

Design advantages and technical properties:

• Finishing Geometry 2 (downward chip flow): Two cutting edges directing chips downwards ensure a clean upper edge of the workpiece and effectively prevent lifting of veneer or laminate.
• Monolithic Premium carbide (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 to apply protective coatings (including TiSiN or PLATINIUM) allows for multiple extensions of the edge life, reduces friction, and protects against overheating.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm protects the mill from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing within standard G2.5: Certified static-dynamic balancing within the rigorous class G2.5 (according to ISO/EN) eliminates noise and reduces vibrations generated at high speeds (up to 18,000 RPM).

Purpose and scope of application:

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

It performs excellently in processing materials such as: soft and hardwood, raw and laminated MDF board, raw and laminated plywood, and raw and laminated particleboard.
