6 Flute Countersinks are the perfect tool for countersinking, chamfering and deburring. The 6 flute construction pronlongs tool life as cutting loads are spread across more cutting edges. Cobalt provides better wear resistance and retains hardness in high temperatures when milling difficult to machine materials.

6-Flute Chatterless Countersinks Developed by Severance Tool, the flutes of the 6-flute Chatterless-Countersinks™ 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.

Designed to countersink, chamfer, deburr and enlarge holes in sheet metal. Use single flute countersinks in holes too small for multi-flute countersinks. Manufactured from premium high-speed steel. Available in 82°- and 90°-point angles. Black oxide finish with bright point increases wear resistance and adds lubricity, improving chip flow. For working in tool steel, alloy steel and cast iron. Recommended for portable applications and machine work. Operate at high speeds and light feed for best results. 30 Day Warranty.
