VHM Spiral Cutter Two-Blade 8x32 mm from the SB51 series – ideal edge quality and high performance

Index: SB51.08.032.080.08R

High-performance spiral cutter made from a solid sintered carbide (VHM) monolith from the SB51 line, intended for precise cutting, shaping, grooving, and slotting on overhead spindle milling machines and CNC centres. The tool employs a two-blade spiral geometry in a Z2 configuration with a negative layout, which ensures effective chip removal downwards. The use of high-quality micro-grain carbide provides high abrasion resistance 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 finish standard of the machined material.

Construction advantages and technical properties:

• Finishing geometry 2 (downward discharge): Two cutting edges directing the material downwards ensure a clean upper edge of the workpiece and effectively prevent lifting of the veneer or laminate.
• Premium Sintered Carbide (VHM) Monolith: The rigid, monolithic structure prevents deformation of the cutter under high forces, allowing for narrow dimensional tolerances to be maintained.
• Possibility to apply PVD coating: The option to apply protective coatings (including TiSiN or PLATINIUM) allows for several times the longevity of the edges, 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 cutter from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing to the strict class G2.5 (according to ISO/EN) eliminates noise and reduces vibrations generated at the highest speeds (up to 18,000 RPM).

Intended use and application range:

The tool is intended for cutting, contour milling, grooving, slotting, 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.
