Solid Tungsten Carbide Downcut Spiral for Hard Plastics & Aluminum Size:SHA 5/16 x 13/16 x 3/8 x 2-1/2 Z2 (Alteration of bore possible ifDowncut Spirals are best suited for sizing, jointing, grooving and dividing in hard plastics and aluminum materials for cutting of openings and contours and traveling plunge cuts using Z and X or Y axis. These spirals are solid carbide, and have a endmill end point type. They provide an excellent finish on the top of the material and a poor finish on the bottom of the material. High rates of feed and best quality thanks to helical geometry.
