## Description

Product Identity: This parallel support block pair is a precision workholding tool designed for use with machine vises and milling machine setups, delivering consistent support for accurate workpiece positioning.
Primary Function: As a machining support block set, it provides parallel, equal-height support to hold workpieces level during milling, and other metalworking operations, reducing setup error.
Material & Hardness: Constructed from hardened alloy steel parallel block set material that has been quenched and hardened to a claimed Hardness 50-60 50–60 hardness, offering wear resistance and long-term durability in workshop environments.
Precision & Features: Each vise setup block features machined flat faces, a silver metal finishengraved size markings for easy identification, and a claimed precision of less than 0.005 mm for reliable, repeatable setups.
Intended Use: Ideal for workshop jigs, fabrication benches, and precision metalworking tasks, this 150 mm long parallel support block pair helps users achieve accurate workpiece alignment for consistent machining results.

When you are setting up a milling machine or machine vise for a precision metalworking job, having a reliable workholding solution makes all the difference. This parallel support block pair is a application-specific workholding tool that fits seamlessly into standard vise and workholding setups, giving you a stable, level base for every workpiece. As a machining support block set, its core job is to lift and support workpieces at a consistent, equal height across both blocks. This parallel height alignment ensures your workpiece sits level relative to the cutting tool, reducing misalignment errors and helping you produce cleaner, more accurate cuts across milling, and facing operations. Built from a hardened alloy steel parallel block set formulation and quenched to a claimed hardness of Hardness 50-60 50–60, these blocks are engineered to stand up to repeated clamping pressure, grinding metal chips, and heavy daily use in a active workshop. The tough construction means they resist deformation and wear, so they maintain their accuracy over time even with frequent use. Each vise setup block is machined to tight tolerances, with a claimed precision of less than 0.005 mm across flat, smooth surfacesengraved size markings are clearly visible block, so you can quickly identify the right pair for your job without fumbling through a mixed set. The silver metal finish gives the parallelishims clean look and makes them easy to set on a crowded workbench. Measuring 150 mm in length with a rectangular profile, these parallel support blocks are well suited for workshop jigs, custom fixtures, fabrication benches, and routine vise setup work. Whether you are setting up -off prototype or running a small production batch, they help you achieve the consistent, repeatable positioning that precision metalworking demands.

Option: 24 PAIR 150 Long
