Drillco 3600E Series High-Speed Steel Countersink, Uncoated (Bright) Finish, 1/2" Shank Diameter, 5/8" Size, 100 Degrees Point Angle

Drillco single flute countersinks should be used when multi-flute countersinks chatter or the hole is too small for a multi-flute countersink to enter. 100 degrees countersink is used to make screw and rivet holes. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. Round shanks allow use with a wide variety of toolholding systems. Right-hand cut tools have a cutting action that engages when they are run in a clockwise direction.
