Amana tool DRB-434 Polycrystaline Diamond (PCD) Tipped Bal Nose 1/4 R x 1/2 D x 1/2 CH x 1/2 Inch SHK Router Bit

2-Flute • Polycrystalline Diamond (PCD) Tipped Bits  Cut half-round grooves for fluted moldings, columns, millwork and signs using a core box bit. Used with an edge guide, it can cut coves. Perfect for making flutes on CNC machines. Diamond is the hardest material on the earth! PCD tooling is manufactured in a high-temperature and high-pressure laboratory that fuses diamond particles onto a carbide substrate which allows the diamond to be brazed onto a tool body. If you’re looking for the ultimate in tooling you’ve found it! Amana Tool's PCD ball nose router bits are designed to eliminate tool marks that commonly appear when used with plastic and solid surface materials. The cutting edge lasts much longer than carbide for extremely long life. Depending on the material being cut PCD tooling has been known to out perform a carbide tool by a ratio of 300:1. However to be conservative in your buying decision we suggest you base your expectations on 25:1 ratio over carbide tooling.
