Iscar’s SD-SP15, a family of narrow slotting and groove milling cutters, features 1.25” diameter milling heads with eight teeth in a width range of 0.125” - 0.250” for maximum depth of cut up to 0.315”.
The cutters consist of interchangeable solid carbide T-slot milling heads and cylindrical steel shanks assembled by means of a unique spline connection. Also available is an adapter with the SP spline connection on one side and T12 Multi-Master threaded connection on the other side, which enables using all T12 standard Multi-Master shanks.
The spline connection is used to transmit the torque in the best way. It ensures durable assembly to withstand considerable cutting forces during slot milling and bending forces caused by long reach overhang. The spline connection designation is SP15, where “15” indicates the connection size.
The general-duty cutting geometry of the heads is suited for efficient slot milling on a spectrum of workpiece materials. The cutter heads feature an SP15 internal spline mounted on a matching external spline on the shank secured by a central screw.
The heads are made from IC908 grade.
