It allows mounting tools with a Morse taper shank MT 2 on machines with a Morse taper seat MT 2 — the larger number is the machine taper, the smaller is the tool taper. The extension sleeve allows the smaller tool to fill the larger seat, maintaining DIN 2187 concentricity.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDifference between extension sleeve and reduction sleeve?\u003c\/summary\u003e\n\u003cp\u003eThe extension sleeve takes a smaller taper (tool) into a larger seat (machine): CM 2\/2 → the machine has MT 2, the tool has MT 2. The reduction sleeve does the opposite — it takes a larger taper into a smaller seat. They are not interchangeable. Always check which one you need before purchasing.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do you remove the sleeve from the Morse taper seat?\u003c\/summary\u003e\n\u003cp\u003eWith the ejector pin (drawbar) that slides into the spindle bore: insert the pin from the opposite side and strike with a hammer. Alternatively, use the flat ejection wedge inserted into the spindle slot. Never force with improvised tools — the Morse taper is self-locking and lateral force can damage the seat.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 working day shipping.
