- n. In mech., a cylindrical bar or spindle, either of uniform diameter, of different diameters, or tapered, used for a variety of purposes, but chiefly for the support of objects formed with holes, into which the mandrel is forcibly driven in order to hold them firmly while turning in a lathe, or in an analogous machine, or in operating upon them with a file. Specifically— An axis attached to the head-stock of a lathe, to support, during the process of turning, any material which is bored or pierced with a central hole. It has often some adjustable device for securing it to the material, and is then known as an adjustable mandrel.
- n. A miners' pick.
- n. In metal-working by the spinning process, the form, usually of wood, upon which the thin plate of metal or blank is pressed in order that the revolution may give it the form of mandrel.
- n. A mandrel fitted to a bearing or bearings of a support which may be set in the tool-post of the slide-rest of a lathe, or in some other traversing device. Such mandrels are used for expanding reamers and analogous tools, and they are usually driven by a pulley-and-belt mechanism.
- To operate upon with mandrels, as a bronze gun. This is done by driving steel mandrels of gradually increasing size through the bore, whereby the strength of the gun is greatly increased, the limit of elasticity being in some cases nearly or quite doubled.
- n. An object used as an aid for shaping a material, e.g. bending a pipe without creasing or kinking it.
- n. A tool or component of a tool that grips or clamps something, such as a workpiece to be machined, a machining tool or a part while it is moved.

“After heat-curing, the mandrel is removed, leaving a hollow tube.”
“A very economical method of clamping is that on the mandrel, which is also called expansion arbor.”
“A mandrel is a spindle or metal shaft around which other parts rotate.”
“THAT is because of the fun and love I found in the torch and glass rods and the mandrel.”
“After the carbon cures, the flexible bladder or silicone mandrel is pulled out through a hole in the rim opposite the valve hole; the hole is patched over afterward.”
“Virtually all deep-section carbon rims are made by molding the rim under pressure and heat while pulling a vacuum on the carbon layers and providing pressure against the carbon layers from the inside by either inflating a bladder inside the rim or by inserting a silicone mandrel inside that is the shape of the inside of the rim.”
“These are two of the eggs that I made in the same off-mandrel lampworking technique class.”
“I made these in an off-mandrel technique class I took at the Mest Art Center from Laurie Nessel.”
“Hint: be sure to rotate your mandrel so the glass can flow into place, I often have my mandrel upside down, so the glass flows next to the mandrel and rounds out on the very top.”
“It's gooey fun to wrap around the mandrel and just oozes where you want it to go.”
