Value Collection 637-7505 Two Face Parallel Tool Steel

Product Description

The VALUE COLLECTION 637-7505 is a two-face precision parallel used in machining, grinding, and layout work to establish accurate reference planes and support workpieces in vises, on surface plates, and in fixture setups. Measuring 6 inches long by 1-1/4 inches high by 3/16 inches thick, it is ground from tool steel hardened to 55-62 HRC for long-term wear resistance. Parallelism is held to 0.0003 inches, making it suitable for precision setups where consistent, repeatable part positioning is critical. Machinists, toolmakers, and setup technicians are the primary users of this type of tooling component.

This parallel is well suited to manual machine shops, CNC setup environments, and quality-inspection stations. Its 3/16-inch thickness makes it appropriate for applications where a slimmer profile is needed inside a vise or under a workpiece. The two-face ground design ensures both faces are usable reference surfaces, doubling effective utility. It is sold individually, making it practical for replacing a single worn or damaged parallel from an existing set without purchasing a full set.

Key Features

• Parallelism of 0.0003 inches for repeatable precision setups
• Accuracy to 0.001 inches across the working surfaces
• Squareness held to 0.0003 inches per 6 inches
• Tool steel construction hardened to 55-62 HRC for wear resistance
• Two-face ground design — both faces serve as usable reference surfaces
• Compact 3/16-inch thickness for use in tight vise and fixture applications

Compatibility

Designed as a standard-profile precision parallel suitable for use with most manual and CNC milling vises, surface plates, and toolroom fixture setups requiring a 6-inch length and 3/16-inch thickness profile.

Installation Notes

Precision parallels are installed and removed by hand or with the aid of a soft mallet — never strike with a steel hammer, as this can damage ground surfaces. Clean the vise and workpiece contact surfaces before placing the parallel to prevent chips or grit from introducing positioning error. Parallels should be stored flat and protected from contact with other hardened tooling to preserve ground surface integrity.
