USED - THE ITEM'S BUTTON PLATE/T-NUT WAS MACHINED. Quick Change Tool Posts, Two Styles - Piston and Wedge.
Both are precision engineered to assure repetitive accuracy. Advanced design provides built-in quick tool changing versatility with positive rigidity to meet the most exacting tolerances. Quickly and easily installed on an engine, bench, or turret lathe for a wide range of operations, from fine precise work to heavy-duty cutting. Piston type posts are economical, while the Wedge type posts are clearly ultra-precise. Both accept the tool holders and interchange with Aloris. The difference between wedge style and piston style quick change tool posts lies in their mechanism for holding and locking tools into place on a lathe. Both types are designed to change tools on a lathe quickly and easily without the need to re-zero the tool position each time. Here are the key differences. Utilizes a wedge mechanism that, when tightened, forces a wedge upward, creating a very tight and secure fit between the tool post and the tool holder. Generally provides superior clamping force and rigidity, leading to better machining accuracy and the ability to handle heavier cuts. Typically more expensive than piston style due to its precision and the quality of machining it can handle. Uses a piston mechanism where a piston expands outward to lock the tool holder in place when the handle is tightened. Flexibility and Ease of Use. Often considered easier to use for quick changes, but may not provide as tight a grip as the wedge style, making it less suitable for very heavy or high-precision machining.

Generally less expensive than the wedge style, making it a popular choice for hobbyists or operations where extreme precision is not as critical. The choice between a Wedge and Piston style tool post depends on your specific needs. If you require high precision and are working with heavy cuts, a Wedge style may be more suitable. If cost is a more significant concern and you're looking for ease of use for more general machining tasks, a piston style might be the better choice.
