Spiral router bit Finishing VHM Z3 D16 I72 L120 S16 RH negative NaDia

Three-flute solid carbide end mill 16x72 mm from the SC51 series – ideal edge quality and high efficiency 

Index: SC51.16.072.120.16XR

High-performance spiral end mill made from solid carbide (VHM) from the SC51 line, designed for precise cutting, shaping, grooving, and finishing on milling machines and CNC centres. The tool employs a three-flute spiral geometry in a Z3 negative arrangement, which facilitates effective chip removal downwards. The use of high-quality micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge's lifespan. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent finish quality of the machined material.

Construction advantages and technical properties:

• Z3 finishing geometry (downward chip flow): Three cutting edges directing chips downwards guarantee a clean upper edge of the workpiece, preventing chipping and effectively avoiding veneer or laminate lift at high feed speeds.
• Premium solid carbide (VHM) construction: The rigid, monolithic structure prevents deformation of the mill under heavy force, allowing for narrow dimensional tolerances to be maintained.
• Possibility of PVD coating: The option for applying protective coatings (e.g., 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 index of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing at a high G2.5 class (according to ISO/EN) mitigates noise and reduces vibrations generated at high speeds (up to 18,000 RPM).

Intended use and application range:

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

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