The "3VPRO" is a high-performance carbide 3-flute end mill with a 90° chamfer that features a twisted blade design for excellent cutting performance, making it less likely to produce burrs. By adopting a 35° twisted blade with three flutes, it reduces cutting resistance and significantly decreases burrs and retraction. It is compatible with a wide range of materials, including "carbon steel," "alloy steel," "pre-hardened steel," and "stainless steel." 【Features】 ■ Excellent cost performance ■ Good cutting performance due to the twisted blade design, making it less likely to produce burrs ■ Reduces cutting resistance and significantly decreases burrs and retraction with the 35° twisted blade ■ Compatible with a wide range of materials from general steel to stainless steel ■ Results in significant cost reduction *For more details, please refer to the PDF document or feel free to contact us.
