VHM Spiral Cutter Two-flute 2x8 mm from the SB51 series – ideal edge quality and high performance

Index: SB51.02.008.060.06R

High-performance spiral cutter made of a solid sintered carbide (VHM) from the SB51 line, designed for precise cutting, contouring, grooving and notching on overhead spindle milling machines and CNC centres. The tool uses a two-flute spiral geometry in a Z2 configuration with a negative arrangement, which enforces effective chip removal downward. The use of high-quality micro-grain carbide ensures high wear resistance and significantly extends the tool life of the cutting edge. A ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing system and guaranteeing an excellent surface finish of the machined material.

Construction advantages and technical properties:

• Finishing geometry 2 (downward discharge): Two cutting edges directing the chips downwards guarantee a clean top edge of the workpiece and effectively prevent lifting of veneer or laminate.
• Premium Sintered Carbide Monolith (VHM): The rigid, monolithic construction prevents deformation of the cutter during heavy-duty operation, allowing for tight dimensional tolerances.
• Possibility of PVD coating: The option to apply protective coatings (e.g., 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 prevents the cutter from spinning in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the high class G2.5 (according to ISO/EN) eliminates noise and reduces vibrations generated at high speeds (up to 18,000 RPM).

Application and scope of use:

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

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