APKT for helical milling is quadrilateral shape of turning insert (85°). Insert with clearance under main cutting edge. Hole through insert and single sided chip breaker. The 3D helical cutting edge can deal with less cutting force. As such most face milling, shoulder milling cutters are using indexable inserts with wedge type clamping or screw-on type clamping to achieve high-quality machining. Our APKT inserts will be your premium choice for helical milling.1.How to choose the right insert? It would be best if you considered many factors to make the right choice regarding carbide inserts. Select insert geometry, insert grade, shape (nose angle), size, nose radius, and entry angle carefully to achieve reasonable chip control and machining performance. 2.How to choose the insert geometry? A turning geometry can be divided into three basic types optimized for different operations: finishing, medium, and roughing. Roughing The combination of high feed rate and depth of cut results in an increased depth of cut. This is suitable for operations requiring the highest degree of edge security. Medium It includes operations that range from medium roughing to light roughing. You can choose something from a wide range of feed rates and depth of cut combinations. Finishing The combination of low feed rates and shallow depths of cut is ideal for shallow depths of cut. Applications that require low cutting force will benefit from this combination. 3.How to choose the grade? Grades of inserts are selected primarily based on: The ISO P, M, K, N, S, and H components indicate the method (finishing, medium, roughing) Manufacturing conditions (good, average, difficult)
