Spiral router bit Finishing VHM Z2 D12,7 I31,75 L76,2 S12,7 RH negative

Two-flute VHM spiral end mill 12.7x31.75 mm from the SB51 series – ideal edge quality and high efficiency

Index: SB51.13.318.762.13R

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

Construction advantages and technical features:

• Finishing geometry 2 (downward ejection): Two cutting edges directing the chips downwards guarantee a clean upper 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 end mill during operation under high force, allowing for narrow dimensional tolerances to be maintained.
• Ability to apply PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for several times increase in edge life, reduces friction and protects against overheating.
• Low roughness of the shank: The shank surface with a roughness index of Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in an improved G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high RPM (up to 18,000 RPM).

Intended use and application range:

The tool is intended for operations such as cutting, contour milling, grooving, notching and edge finishing.

It works excellently with materials such as: soft and hard wood, raw and laminated MDF board, raw and laminated plywood, and raw and laminated chipboard.
