MZG T-Slot Cutter System
T-slot cutters are a specialized type of milling cutter specifically designed for machining T-slots. These slots are widely used in machine tables, fixtures, and other components for inserting and securing T-head bolts. Our comprehensive T-slot cutter system includes Welding T-type milling cutters for mold processing, Tungsten steel T-groove side milling cutters for general applications, and Dovetail groove milling cutters for precision mechanical connections with various angle configurations (45°, 60°, 90°).

Product Performance
T-slot cutters are a specialized type of milling cutter specifically designed for machining T-slots. These slots are widely used in machine tables, fixtures, and other components for inserting and securing T-head bolts. T-slots are a fundamental feature in numerous industrial applications, prominently including machine tool table beds (e.g., on milling machines and drill presses), workholding fixtures, and various assembly components where adjustable and secure clamping is paramount.
The cutter's distinct geometry features a smaller diameter neck positioned behind a larger diameter cutting head. This design allows the tool to first enter a pre-machined straight slot (often created by an end mill or slot drill of appropriate width) and subsequently cut laterally to form the wider, undercut sections that define the characteristic "T" profile.
Our T-slot cutters include three main categories: Welding T-type milling cutters featuring cutting inserts welded onto the tool body for mold processing, Tungsten steel T-groove side milling cutters for general T-slot machining in steel and non-ferrous metals, and Dovetail groove milling cutters specifically designed for machining dovetail slots with various angle configurations (45°, 60°, 90°).
