Value Collection 251-3704 Live Center Taper Shank MT3

Product Description

The VALUE COLLECTION 251-3704 is a taper shank live center designed for use in metal lathes and cylindrical grinding machines. It features a bull nose point style with a 4-inch head diameter and a head length of 2.76 inches, giving it a robust profile suited for heavy-duty turning operations. The center is built from steel and uses an MT3 (Morse Taper 3) shank for secure, repeatable seating in the tailstock. With a maximum workpiece weight of 600 pounds and a load capacity of 660 pounds, this unit handles demanding stock. Machinists and tool-room operators working with large-diameter or heavy workpieces will find the bull nose profile essential for parts where a standard point would not support properly.

This live center is intended for use in machine shop environments, including production turning, repair facilities, and toolroom applications. It seats in an MT3 tailstock and supports workpieces up to 600 pounds at spindle speeds up to 500 RPM. The bull nose point makes it appropriate for hollow or faced workpieces that cannot accept a standard point tip. It is suited for both manual and CNC lathes equipped with an MT3 tailstock bore.

Key Features

• MT3 taper shank for direct seating in standard MT3 tailstock bores
• Bull nose point style supports hollow, faced, or large-bore workpieces
• 4-inch head diameter and 2.76-inch head length for heavy-stock clearance
• Maximum workpiece weight of 600 pounds with a radial load capacity of 660 pounds
• Thrust load rating of 520 pounds for axial cutting forces
• Accuracy of 0.0005 inches for reliable concentricity in precision turning
• Maximum spindle speed of 500 RPM

Compatibility

Designed to fit any lathe or cylindrical grinder equipped with an MT3 (Morse Taper 3) tailstock. Verify tailstock bore taper size before installation.

Installation Notes

Installation should be performed by a qualified machinist. Power down and lock out the lathe before seating or removing the center from the tailstock. Clean both the MT3 shank and the tailstock bore thoroughly before seating to ensure full contact and concentricity. Never exceed the rated maximum RPM or workpiece weight, as overloading the center can cause premature bearing failure or workpiece ejection.
