Precision MT4 Bull Nose Live Center 75° Morse Taper #4 Lathe Tailstock Center

This is a new bull nose live center with a Morse Taper #4 (MT4) shank, featuring a 75° included cone angle on the large-diameter rotating bull nose head — confirmed by the product label ("Bull Nose Live Center with MT4 tape[r]," SKU 00453332, Made in India) visible on the packaging. The bull nose design accommodates large-bore hollow or tubular workpieces that a standard point center cannot support, with the wide conical face engaging the chamfered inner bore of the workpiece rather than a center-drilled point. The rotating head rides on internal ball or roller bearings (visible as the black bearing race in the face-on photo), allowing the cone to spin freely with the workpiece and eliminating heat buildup and galling under tailstock pressure. The MT4 shank fits directly into any lathe tailstock with a #4 Morse Taper quill bore, a common size on engine lathes in the 14–17+ inch swing range. Construction is alloy steel throughout, with the shank ground to MT4 tolerance and the outer cone face finish-turned; the shank tang is present for drift-key ejection.
