Lathe centers are the tooling that allows workpieces to be held and rotated precisely on the lathe spindle centerline, making between-center turning possible. When a workpiece is supported by centers at both the headstock and tailstock ends, it is aligned exactly with the spindle axis and can be turned to precise cylindrical geometry even at high length-to-diameter ratios where a chuck-held workpiece would deflect and chatter.
The collection of lathe centers at Buyohlic covers every type and Morse taper size for US machine shops and home machinists. Live revolving centers for tailstock use, dead centers for both headstock and tailstock applications, carbide-tipped dead centers for hardened workpieces, half centers for turning to a shoulder without interference, and pipe centers for hollow or thin-walled workpieces each serve specific applications in a complete turning operation capability.
Types of Lathe Centers
The standard 60-degree center angle is the universal angle for most turning work. The workpiece end is drilled with a matching 60-degree center drill to create a conical seat that engages the center point. This geometry distributes the support force evenly over the cone surface and keeps the workpiece precisely aligned with the spindle axis throughout the turning operation.
Carbide-tipped dead centers are used when turning hardened workpieces at high speeds that would wear a standard hardened steel center point quickly. The carbide tip resists abrasion from the hardened workpiece center hole surface, maintaining point geometry and supporting accuracy over many production parts.
Half centers have one quadrant of the 60-degree cone removed, leaving a flat that provides clearance for a facing tool to reach the end face of the workpiece without striking the center. This allows the end face to be faced to final dimension while the workpiece is still supported between centers, without removing the tailstock center first.
Selecting the Right Center for Your Application
- Between-center turning on a manual lathe: live revolving center at tailstock, dead center or drive dog at headstock
- High-speed turning with heavy cuts: live center with high load capacity rating
- Hardened workpieces: carbide-tipped dead center to prevent tip wear from hard material
- Facing the end of a center-supported part: half center at tailstock to provide tool clearance
- Hollow or thin-walled workpieces: pipe center that supports the outside of the tube end

Frequently Asked Questions - Lathe Centers
Use a combination center drill (also called a slocombe drill) which has a small diameter pilot drill followed by a 60-degree countersink. The pilot drill creates the depth of the center hole while the countersink creates the seating cone for the lathe center. Center drills are available in sizes 1 through 6, with size 2 being the most common for typical workpiece diameters in a general purpose shop. The center hole should be deep enough that the center point does not bottom out in the hole, allowing the cone surfaces to make full contact.
For dead centers, apply a small amount of center lubricant or cutting oil to the center hole before mounting the workpiece. For live revolving centers, no lubrication is needed as the center rotates with the workpiece. Check that the tailstock is applying the correct amount of pressure. Too light and the workpiece will chatter; too heavy and excessive friction and heat will score the center hole even with lubrication. Adjust the tailstock handwheel until the workpiece is firmly supported with slight resistance when rotated by hand.
Yes, but only with cutting oil applied constantly to the center hole, and at lower spindle speeds than you would use with a live center. The workpiece center hole and the dead center tip will generate heat from friction. For any turning at moderate to high spindle speeds, a live revolving center is strongly preferred over a dead center at the tailstock. Dead centers in the tailstock are mainly used in precision grinding operations where the minute flex in a live center bearing must be eliminated for maximum accuracy.
