Finish milling cutter VHM Z2 D3 I12 L60 S6 RH negative

Two-flute spiral end mill 3x12 mm from the SB51 series – ideal edge quality and high efficiency

Index: SB51.03.012.060.06R

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

Design advantages and technical properties:

• Finishing geometry 2 (downward ejection): Two cutting edges directing the chips down guarantee a clean upper edge of the workpiece and effectively prevent lifting of the veneer or laminate.
• Premium sintered carbide monolith (VHM): The stiff, monolithic structure prevents deformation of the end mill during heavy load operations, allowing for narrow dimensional tolerances to be maintained.
• Option for PVD coating application: The option of applying protective coatings (including TiSiN or PLATINIUM) allows for multiple extensions of the edge's lifespan, reduces friction, and protects against overheating.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Intended use and scope of application:

The tool is intended for cutting operations, contour milling, grooving, fluting, and edge finishing.

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