About Modular Insert Tooling
Tormach’s Modular Insert Tooling is an interchangeable system of carbide insert cutters, cutter heads, and TTS cutter mounts for the ultimate in flexible quick-change cutting tools. With replaceable cutting inserts and a variety of tool lengths and cutter head styles available, machinists can now build a tool custom tailored to their milling application.Insert cutters offer lower cutting forces, longer tool life, and lower operating costs over solid tooling. Each cutting head uses carbide inserts with modern geometries and are compatible with similar brand name inserts from Sandvik, Ingersoll, Mitsubishi, and other suppliers.
Mounts: Mounts are specified by both length (Long, Medium, and Short) and accepted stud size (4mm, 8mm, 10mm, and 12mm).
Heads: Cutter heads are available in a variety of geometries and diameters. Cutter heads have 4mm, 8mm, 10mm, or 12mm studs. Match the stud size of the cutter head to the correct mount size for compatibility.
Inserts: Each cutter head uses a set of inserts that are matched to the head. Depending on style, inserts can be rotated (or “indexed”) 2 or more times as cutting edges dull to get new edges and additional cutting life. Each cutter head requires up to 4 inserts, depending on style.
Screws and Tools: One mounting screw is required for each insert. Match the screw size to the insert style when ordering. A star head wrench tool is available and needed for each screw size. Anti-seize should be applied to each screw.
