The Square T4 helical cutter range takes our diverse milling portfolio to the next level with tools that features tangentially mounted inserts, each having 4 cutting edges. Tangential mounting reinforces insert stability, improves chip flow and provides unrestricted access to mounting screws, while multiple cutting edges help reduce tool cost per part. Additionally, such a mounting design directs the cutting forces to the thickest part of the inserts, providing highly robust milling performance and increased metal removal rates.
