T-Slot Milling Cutter 60 Degree Tungsten Steel Carbide CNC Machining Center Cutting Tool 4-Blade For Aluminum Steel

A T-slot cutter, also known as a T-slot milling cutter, is a specialized type of milling cutter designed exclusively for milling T-slots. It has a distinctive structure: the cutter body is either straight shank or taper shank, with a protruding cutting head whose cutting edges are perpendicular to the spindle. It resembles a vertical combination of a small end mill and a disc cutter. This unique design allows it to first use an end mill to create a straight groove, and then use the T-slot cutter to mill out the wider bottom section, thus forming the T-shaped profile.
