Spiral router bit Finishing VHM Z2 D12 I35 L83 S12 RH negative

Two-flute VHM spiral end mill 12x35 mm from the SB51 series – ideal edge quality and high performance

Index: SB51.12.035.083.12R

High-performance spiral end mill made of solid sintered carbide (VHM) from the SB51 line, designed for precise cutting, shaping, slotting, and grooving on vertical spindle milling machines and CNC centres. The tool features a two-flute spiral geometry in a Z2 negative arrangement, which ensures effective chip removal downwards. The use of high-quality micrograin carbide provides excellent wear resistance and significantly extends the cutting edge's lifespan. The ground shank in tolerance class H6 minimizes radial run-out, protecting the spindle bearing system and guaranteeing an excellent finishing standard of the machined material.

Design advantages and technical properties:

• Finishing geometry 2 (downward discharge): Two cutting edges directing the cut material downwards ensure a clean top edge of the workpiece and effectively prevent lifting of veneer or laminate.
• Premium sintered carbide monolith (VHM): Rigid monolithic construction prevents deformation of the mill during operation under high forces, allowing for the maintenance of narrow dimensional tolerances.
• Coating option PVD: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of the edge 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 mill from rotating in the chuck and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the strict class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at the highest speeds (up to 18,000 RPM).

Intended use and application range:

The tool is intended for cutting, peripheral milling, slotting, grooving, and finishing edge operations.

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