Value Collection 637-7500 Two Face Parallel Tool Steel

Product Description

The VALUE COLLECTION 637-7500 is a two face parallel used in precision machining and metrology applications. Ground from tool steel and hardened to 55-62 HRC, this parallel delivers a parallelism tolerance of 0.0003 inches per 6 inches and an accuracy of 0.001 inches. It measures 6 inches long by 1 inch high by 0.5 inches thick. Machinists, tool and die makers, and quality control technicians use parallels like this one to support and level workpieces in vises, on surface plates, and during inspection setups. Each unit is sold individually.

This parallel is suited for use in precision machine shops, toolrooms, and inspection departments. It is appropriate for both manual milling and grinding operations where consistent, repeatable workpiece elevation is required. The two face design means both top and bottom faces are precision ground, making it reversible and giving users a reliable seating surface regardless of orientation. Typical applications include workholding in milling vises, layout work, and surface grinder setups.

Key Features

• Parallelism of 0.0003 inches per 6 inches for repeatable precision setups
• Accuracy to 0.001 inches across the working faces
• Hardened tool steel at 55-62 HRC for wear resistance and long service life
• Two face ground design allows reversible use
• Compact 6 x 1 x 0.5 inch profile fits standard milling vises
• Sold as a single unit with a minimum order quantity of 1

Compatibility

Designed as a standard toolroom parallel suitable for use in conventional milling vises, surface grinders, and precision layout applications requiring a 6-inch working length.

Installation Notes

Parallels are handled and positioned by machinists and toolroom technicians — no power source or mechanical installation is required. Clean the vise jaw faces and the parallel surfaces before use to remove chips, oils, or debris that can affect seating accuracy. Inspect parallel faces periodically for nicks or burrs and dress lightly with a fine stone if needed. Store parallels flat or in a dedicated rack to prevent edge damage and maintain tolerance integrity.
