The beauty of these revolutionary new turning tools is not really the hefty, 15'' brightly finished maple handles, but the uniquely designed carbide cutters. Say goodbye to sharpening as these cutters, which add up to 20 additional hours of turning from each of the four-sides, are replaceable once dulled. Secondly, the cutters designed so that you dont have to find the bevel when turning. Simply advance the tool slowly into the work piece and begin cutting straight in, or sweep the cutter from left to right, or right to left. The Full-Size Easy Rougher hogs material off effortlessly by transferring cutting pressure directly to the tool rest and comes with the standard R4, 4'' radius cutter for roughing larger pieces. Optional cutters include an R2, 2'' radius used for finishing inside bowls under 8''in diameter and a square head cutter for roughing and creating square inside corners.
