Parallels

Steel parallels raise and support work at a precise, uniform height for milling, drilling, layout, and surface grinding, keeping parts flat and square in the vise or on the table. Matched, hardened pairs and sets are indispensable to machinists and toolmakers who rely on consistent, dependable setups. Suburban Tool steel parallels are Made in USA and ground to tight parallelism, thickness, and squareness tolerances.The range includes non-tipping parallels, four-way parallels, thin-wall styles, and precision sets (P4W, TWP9, TWP22) in a wide span of sizes and in both inch and metric. Use the filters to sort by size, style, or set, or contact Suburban Tool for custom sizes and special parallels.
