<B>6-Flute Chatterless Countersinks</b><br><br>Developed by Severance Tool, the flutes of the 6-flute Chatterless-Countersinks&#8482; are designed with staggered cutting angles to eliminate the harmonics that cause chatter in conventional tools. They feature a positive shearing action, are designed to take heavy cuts and produce exceptionally smooth seats. These six fluted countersinks give long service life because the cutting load is distributed over six cutting edges. Use them in your milling machine, drill press, screw machine, lathes, automatics, special machines, feed units, and hand tools.<br><br>
