The dead center is more precise (no radial play from bearings) but requires frequent lubrication and is not suitable for high speeds. For low-speed finishing turning, the dead center is preferable; for roughing and production, the revolving type is the standard choice.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCompatible with MT 3 — how is it mounted on the lathe tailstock?\u003c\/summary\u003e\n\u003cp\u003eThe MT 3 taper is inserted into the Morse taper socket of the lathe tailstock. No tools are necessary — it is inserted by hand, and the taper friction locks it during use. To remove it, use the tailstock's extractor pin or extraction wedge. The tip of the revolving live center must be lubricated periodically.\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 business days shipping.
