This versatile boxed set may be the answer to ALL your slot cutting needs. It includes six 3-wing slot cutters with 1/16″, 3/32″, 1/8″, 5/32″, 3/16″ and 1/4″ kerfs. All are 2" diameter with 9/16″ cutting depth. Multiple shims included with 1/4" shank arbor allow for versatility in placement of cutters. A shim must also be positioned between the ball bearing and the cutters. Cutters may be stacked if properly shimmed between each cutter to ensure no contact with carbide tips.
