The Izar 9446 is a high-precision radius (corner-rounding) solid carbide endmill made from UF micro-grain carbide, featuring 4 flutes, a 1.00 mm corner radius, and an unequal-variable helix (IKRA) for excellent vibration dampening. Built to DIN 6528 N specifications and equipped with a flat shank, this tool delivers smoother finishes and enhanced tool stability—especially on challenging materials such as alloy steels, stainless steels, and copper alloys.

Geometry & Benefits

1.00 mm corner radius: Strengthens the cutting edge, distributes load, improves tool life, and yields smoother surface finishes on vertical faces.
Unequal-variable helix (IKRA): Suppresses chatter by breaking up harmonics, offering high fidelity surface finish and vibration-free operation.
UF micro-grain carbide: Delivers outstanding rigidity, edge durability, and resistance to wear—a solid choice for precision machining.
4-flute setup: Enhances tool strength while facilitating efficient chip removal, balancing rigidity with material evacuation.
DIN 6528 N standard geometry: Delivers predictable, repeatable results compatible with standard toolholders and machining routines.

Applications & Material Suitability

Perfect for operations that demand surface quality and precision:

Finishing profiling and corner rounding on materials like alloyed steels, heat-treatable steels, stainless steels, and copper/brass.
Suitable for high-speed CNC operations where chatter suppression and edge retention matter.
Ideal for components requiring smooth transitions between surfaces, such as molds, die cavities, aerospace parts, and marine components.
