IMCO SJ Cone-Shape Coutersink Burs 60º

Product Description

Bur Cut Styles

* Select the cut style for the finish you need from the choices below.
* Precision flute grinding ensures chatterless operations and a long tool life.

► Double cut

* Right- and left-hand flutes combine to produce a chisel-type cutting edge.
* You get faster penetration and stock removal, and better control and less operator fatigue due to reduced pull.

► Standard cut

* This style has only right-hand spiral flutes, producing good stock removal and excellent surface finishes.
* Use this cut for general deburring in cast iron, steel, copper alloys, brass alloys and other ferrous materials.

► Aluma Cut

* Wide flutes make the aluma cut ideal for easy chip clearance.
* That means fast stock removal in aluminum, brass, zinc alloys, most plastics and soft, non-ferrous materials.
* IMCO’s advanced relief design gives it greater strength, so it lasts a lot longer.
