Gibraltar TVS-20 Toolmaker Vise 1.97 in Jaw Flat Jaw Steel

Product Description

The GIBRALTAR TVS-20 is a flat-jaw toolmaker's vise built for precision workholding on milling machines, surface grinders, and inspection tables. The vise features a 1.97-inch jaw width and a 2.56-inch jaw opening capacity, giving technicians a secure grip on small to medium workpieces that require tight positional accuracy. Parallelism is held to 0.003 inches and squareness to 0.005 inches, making this vise suitable for close-tolerance machining and grinding operations. The all-steel construction supports repeated clamping cycles without significant deflection. At 3.96 pounds, it is compact enough for bench or machine table use without adding unnecessary mass to the setup.

The TVS-20 is intended for machine shops, tool rooms, and precision grinding applications where repeatable workholding is critical. It is a common choice for setups on small surface grinders and milling machines where a Kurt-style vise would be oversized. The flat jaw profile keeps the vise low-profile, reducing overhang and improving rigidity during light cuts or grinding passes. Machinists, toolmakers, and skilled trade technicians working in production or job-shop environments are the primary installers and users of this vise.

Key Features

• Flat jaw design maintains a low profile for grinding and milling setups
• Parallelism within 0.003 inches for close-tolerance workholding
• Squareness within 0.005 inches ensures accurate part orientation
• 1.97-inch jaw width accommodates small to medium workpieces
• 2.56-inch jaw opening capacity for a range of part sizes
• All-steel construction for durability and rigidity under repeated clamping

Compatibility

Designed as an OEM-style precision toolmaker's vise suitable for use on standard T-slot machine tables in milling and surface grinding applications.

Installation Notes

Installation is typically performed by a machinist or toolmaker using T-bolts and nuts sized to the machine table slot. The machine spindle or wheel should be fully stopped and the machine powered down before mounting or repositioning the vise. Verify the vise is seated flat on the table and indicate it in with a dial test indicator before tightening fasteners to full torque. Cleaning all mating surfaces before mounting helps maintain the stated parallelism and squareness tolerances.
