Gibraltar 428-72012 Machine Vise 4 in Angle Swivel Base

Product Description

The GIBRALTAR 428-72012 is a manual machine vise designed for workholding on milling machines, drill presses, and similar metalworking equipment. It features a 4-inch jaw width and 4-inch jaw opening, giving machinists and toolroom technicians a solid clamping range for a variety of stock sizes. The swivel base allows the vise body to rotate for angled setups, and the angle orientation type supports tilted workpiece positioning. At 35 pounds, this is a substantial cast unit built for stable fixturing under cutting loads. Installation and removal are performed by licensed machinists or skilled trades professionals working in shop environments.

This vise suits typical single-station workholding applications in production shops, toolrooms, and maintenance facilities. The 12-inch overall length and 6.25-inch overall height fit standard milling machine tables and drill press tables used in both light industrial and job-shop settings. The manual operation requires no hydraulic or pneumatic supply, making it straightforward to deploy wherever a T-slot table is available.

Installation Notes

A qualified machinist or toolroom technician should mount this vise to the machine table using appropriate T-slot bolts and a torque wrench following the machine manufacturer's table-clamping guidelines. Ensure the machine is powered down and the spindle is at rest before mounting or repositioning the vise. Use a dial indicator to confirm jaw alignment to the machine axis before committing to a workholding setup. Do not exceed the jaw opening rating when clamping oversized stock.
