It allows the use of larger MT 3 shank tools in machines with a smaller MT 1 socket — the opposite of an extension sleeve.

For high-precision grinding and boring, where concentricity \u0026lt;0.005 mm is critical, prefer tools with the machine's native taper.\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.
