The 1/4" Up-Down Spiral Compression CNC Router Bit is a meticulously engineered tool built for precision and efficiency in cutting tasks. Constructed from solid carbide, it boasts a cutting tip diameter of 1/4", a shank diameter of 1/4", a length of cut of 1", and a spiral change of 0.22". This design is optimized for CNC/Router applications, especially where high feed rates and clean compression cuts are a priority. The bit is particularly adept for double-sided melamine or laminated materials. One of the standout features is the Astra coating, which significantly enhances performance by providing higher cutting speeds, feed rates, and extended tool life, especially in abrasive materials. This up-down spiral bit is a versatile and indispensable asset for any workshop that values precision and high-quality output in its projects.
