Milled from a solid steel blank, this carbide-tipped, 1/2" shank rosette cutter makes crisp rosettes in most hardwoods and softwoods. Please note, although this cutter looks like an oversized router bit, it is too big for normal router speeds and are designed for use with your variable-speed drill press or lathe. Max RPM: 15,000.
