About Econo-Sink™ 4-Flute Countersinks

Econo-Sinks have a Chatter-Free four-flute design, with four staggered cutting teeth arranged for free chip flow and rapid Chatter-Free cutting. They give better finishes, higher production and more economic value than a single flute tool, and suit a wide range of materials including non-ferrous and other stringy materials and cast iron. HSS 1/8" to 3", carbide 1/8" to 1", in all standard angles.

Available in premium M2 High-Speed Steel and Carbide.
