Riten 68113 Solid Dead Center Long Point 3MT Morse Taper

Product Description

The RITEN 68113 is a solid dead center designed for lathe and turning applications where a fixed, non-rotating center point is required. Built from steel with a long-point geometry, this dead center features a No. 3 Morse Taper shank for direct spindle or tailstock mounting. The head diameter measures 3/8 inches, with a matching point diameter of 3/8 inches and a point length of 1-1/4 inches. Overall length is 1-11/16 inches. Accuracy is held to 0.00005 inches, making it suitable for precision turning work. Licensed machinists and lathe operators install this type of center in production and toolroom environments.

This solid dead center is used in metal-turning operations on manual and CNC lathes equipped with a No. 3 Morse Taper tailstock or spindle bore. Its long-point style provides clearance for small-diameter workpieces and deep-hole turning setups. The 7/8-14 thread size supports draw-bar or retention configurations on compatible spindle setups. Typical applications include precision shaft turning, cylindrical grinding support, and workholding in both job-shop and production machining environments.

Key Features

• Solid steel construction - no rotation, no bearing wear, full rigidity under load
• Long-point geometry for improved clearance on small-diameter and deep-reach turning work
• No. 3 Morse Taper shank for direct mount in standard tailstock or spindle bores
• Accuracy of 0.00005 inches for precision turning and cylindrical grinding applications
• 7/8-14 thread size for draw-bar retention compatibility
• Compact 1-11/16 inch overall length minimizes overhang in the tailstock

Compatibility

Designed as an OEM-style solid dead center for lathes and turning machines equipped with a No. 3 Morse Taper (3MT) tailstock or spindle bore.

Installation Notes

Installation is performed by qualified machinists or lathe operators. Power down and de-energize the lathe spindle before inserting or removing the center. Clean the Morse Taper bore and the shank with a lint-free cloth before seating to ensure full taper contact and prevent fretting. Dead centers generate heat at the contact point during turning - use appropriate cutting fluid or lubrication at the center tip, and monitor workpiece temperature during extended cuts.
