The P88003 set is a set of five different shaped rotary carbide burrs from Dormer to cope with most of your needs when de-burring stainless steels. Each set consists of a P601, which is Shape A (cylinder without endcut); P605, Shape C (ball-nosed cylinder); P607, Shape D (ball); P611, Shape F (ball nosed tree); and P621, Shape L (ball nosed cone). All five burrs in the set are made from premium carbide, giving excellent performance and extended tool life at high speeds. The toughened and hardened steel shanks provides rigidity and strength, decreasing vibrations and so extending the life of the tools. The burrs all have VA geometry to maximize material removal when machining stainless steels, whilst the bright finish prevents workpiece material from sticking to the cutting edges of the tool, so you get a clean finish..
