Spiral router bit Finishing VHM Z2 D12,7 I38,1 L88,9 S12,7 RH negative

Two-flute VHM spiral cutter 12.7x38.1 mm from the SB51 series – ideal edge quality and high performance

Index: SB51.13.381.889.13R

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

Design advantages and technical properties:

• Finishing geometry 2 (downward eject): Two cutting edges directing the chips downwards ensure a clean upper edge of the workpiece and effectively prevent lifting of the veneer or laminate.
• Monolith of Premium sintered carbide (VHM): Rigid, monolithic construction prevents deformation of the cutter under high force, allowing for narrow dimensional tolerances to be maintained.
• Possibility of PVD coating: The option to apply protective layers (such as TiSiN or PLATINIUM) allows for multiple extensions of 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 rotating in the holder and eliminates the risk of wearing the taper in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in an exceptional G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds (up to 18,000 RPM).

Intended use and applications:

The tool is intended for cutting, peripheral milling, grooving, profiling, and finishing edge machining.

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