This block is used for rough planing and routing out curved elements on a ring fence by using a template. The block is fitted with 12 TC knives, each with four cutting edges. Just loosen each knife and rotate to a fresh edge when blunt. The blades are positioned on a spiral for a low noise and clean cut. The block is 100mm high, 80mm diameter and made from high tensile alloy for low weight and strength. Best results between 4,000 to 6,000 rpm (max speed 9,000 rpm).

What am I doing wrong ?So guys, I bought this spiral head with bearings as I thought it was the answer to template shaping tall items like boxes. I tried it on a test piece ( an all concave box ) but got quiet a few white knuckle dig ins.The box was grabbed out of my hands. I was disappointed as I expected a silky smooth cut. It was a finger jointed box but I wouldn't have expected the end grain fingers to put up much resistance. The spindle speed was medium -12,000 .Its quite hard to find info on this tool online, hence my post here. - any comments ?
