Double Angle Cutters are an extremely versatile milling tool capable of performing thread milling, chamfering, back chamfering, machining V-grooves, deburring and counter sinking. Double Angle Cutters with a 60° angle can create internal and external 60° Unified National (UN) and metric threads. For chamfering, the angle of the top or bottom of the cutting face (double cutter angle/2) will determine the chamfer angle. Similarly, a back chamfer will be the same process but chamfering underneath the part. Machining V-grooves is very effective with a double angle cutter because the cutting head is perpendicular to the tool centerline. Deburring is an easy process with a double angle cutter and can be performed easily within the CNC machine. Countersinking is performed by using the bottom cutting face of the double angle cutter. RedLine Tools offers 30°, 45°, 60°, 90° and 120° double angle cutters either uncoated or AlTiN coated. These cutters are proudly made in the USA from High Quality Carbide.
