Gibraltar 428-72692 Machine Vise 6 in Swivel Base

Product Description

The GIBRALTAR 428-72692 is a horizontal machine vise with a 6-inch jaw width and a swivel base, designed for secure workpiece clamping during machining operations. Manual operation gives the operator direct control over clamping force. With a jaw height of 1.625 inches and a throat depth of 1.625 inches, this vise is suited to gripping stock at consistent, repeatable angles. The swivel base allows repositioning the jaw assembly without unclamping the vise from the table, streamlining multi-angle setups. At 109 pounds, this is a substantial, rigid unit built for production and job-shop environments where stability and repeatability matter.

This machine vise is appropriate for use on vertical and horizontal milling machines, drill presses, and surface grinders in single-station setups. The horizontal orientation makes it well suited to end milling, face milling, and drilling operations where the workpiece is held flat against the fixed jaw. Machinists and tool-and-die tradespeople will find the swivel base especially useful for angular work and compound setups without requiring a separate sine vise or rotary table for moderate angular offsets.

Key Features

• 6-inch jaw width accommodates a wide range of stock sizes in a single-station configuration
• Swivel base enables angular repositioning without removing the vise from the machine table
• 1.625-inch jaw height and 1.625-inch throat depth provide solid grip on low-profile and standard workpieces
• Manual operation delivers direct, tactile clamping force control
• Precision-grade construction supports accurate, repeatable setups
• Overall height of 6.25 inches keeps the workpiece at a consistent, stable elevation above the table surface

Compatibility

Designed as a single-station horizontal machine vise for use on standard milling machine tables, drill presses, and surface grinders that accept vise-mount tooling.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Before mounting, ensure the machine table and vise base are clean and free of chips or burrs that could affect seating accuracy. Secure the vise using appropriate T-slot bolts and strap clamps rated for the table slot size. Verify jaw alignment with a dial indicator before beginning operations to confirm the vise is trammed square to the machine spindle.
