It allows you to mount tools with an MT 5 Morse taper shank on machines with an MT 5 Morse taper spindle – 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 an extension sleeve and a reduction sleeve?\u003c\/summary\u003e\n\u003cp\u003eAn extension sleeve holds a smaller taper (tool) in a larger spindle (machine): MT 5\/5 → the machine has MT 5, the tool has MT 5. A reduction sleeve does the opposite – it holds a larger taper in a smaller spindle. 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 spindle?\u003c\/summary\u003e\n\u003cp\u003eUsing the knockout pin (drawbar) that runs through the spindle bore: insert the pin from the opposite side and tap with a hammer. Alternatively, use the flat drift key 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 days shipping.
