Severance Chatter Free® Stop Countersink Cutter 90 Degree 3/8" Diameter #30 Pilot Hole

Designed for use with Hougen® Magnetic Drills, 82° Countersink with Carbide Inserts (Does not include pilots).

Particularly designed for countersinking or light chamfers in workable material. Smooth and burr-free finish.

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.

Ideal for chamfering deburring and countersinking. The large positive rake and single flute construction provides a smooth surface finish on a wide variety of materials. The versatility of this tool should increase productivity on all general purpose applications.

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.
