Replaceable steel plates for broad compatibility Includes three interchangeable steel plates to fit shafts of different diameters. Swap plates quickly to match the shaft size you are working on without replacing the entire rest. Clear, durable scale for precise positioning The main body features a clear, easytoread scale engraved on an alloy surface that resists wear. The durable scale helps you position the rest more accurately and repeat settings reliably. Flexible adjustment and simple installation Comes with installation tools and a wrench. The adjustable design lets you finetune the rest position quickly to improve machining accuracy and repeatability. Easy to install and adjust on the job. Lightweight, sturdy construction Made from aluminum alloy for a good strengthtoweight ratio. The steel plates provide robust contact surfaces while the alloy body keeps the assembly light and corrosionresistant for longlasting performance. Key benefits — why you need this product Saves time and cost by allowing plate replacement instead of replacing the whole rest when working with different shaft sizes. Improves work accuracy through a clear, wearresistant scale and fine adjustment capability. Reduces operator fatigue with a lightweight but durable body that holds up under repeated use. Typical applications Lathe work: support and steady shafts during turning and finishing operations where different shaft diameters are used. Maintenance and : hold rotating shafts securely during disassembly, inspection, or reassembly tasks. Smallbatch machining or DIY metalwork/woodwork: quickly adapt to varied workpieces without swapping whole fixtures.
