International Tools reducing sleeves DIN 2185, from MT 1 to MT 6
International Tools reducing sleeves, also called drill sleeves, let a drill or tool holder with a smaller Morse taper fit a machine with a larger Morse taper. You use them on pillar drills, lathes and milling machines to mount tools with different shanks on the same spindle.
The sleeves follow DIN 2185 and are named by the outer taper to the inner taper, from MT 2 to MT 1 up to MT 6 to MT 5 (marked MK in the product names). Choose the outer size by the spindle of your machine and the inner size by the shank of your drill. To bridge several steps, there are sleeves that go straight from MT 4, MT 5 or MT 6 to a much smaller size, so you do not have to stack sleeves. Keep the tapers clean and free of grease, because dust or a burr costs clamping force and accuracy.
There are also universal Quick-Change holders and adapters for diameters from 14 to 210 mm, with an 11/32" (8.7 mm) shank, for fast tool changes. These parts belong to the International Tools machining tools, alongside the matching cutting tools.
