Bison-Bial workbench vise base 5" BBI-0642-21-175

The Bison-Bial workbench vise base 5" BBI-0642-21-175 is a mounting base designed to secure a 5-inch bench vise to a workbench or machine table. It provides a stable attachment point with a swivel function to allow positioning of the vise, and a fixed mounting surface to keep the vise secure during metalworking, woodworking and general workshop tasks. The product is intended to improve vise stability and repeatability of clamp placement while preserving access to the workpiece.

Advantages

The vise base offers a solid bearing surface and a robust swivel mechanism that enables controlled rotation of the vise while maintaining clamping security. Constructed for workshop use, it simplifies installation of a 5-inch vise and reduces direct wear on the mounting surface by concentrating loads through a defined base. The design supports reliable mounting on a variety of bench or table thicknesses and helps keep the vise aligned during repeated operations.

Suitable for

• Mounting a 5-inch bench vise on a workshop bench or machine table
• Metalworking tasks requiring a stable and rotatable vise platform
• Woodworking operations that benefit from secure vise positioning
• General repair, assembly and light fabrication work in home or professional workshops

Key specifications

• Compatible vise size: 5-inch bench vise
• Mounting type: swivel base with fixed clamp-down position
• Material: workshop-grade metal construction for load-bearing support
• Intended mounting surface: workbench or machine table
• Function: provides stable attachment and controlled rotation of the vise

How to use

Position the base on the desired location of the workbench or machine table and mark mounting holes according to the base footprint. Fasten the base securely to the bench using appropriate bolts or screws for the bench material and thickness, ensuring the mounting hardware is tightened to provide a firm connection. Attach the 5-inch vise to the base following the vise manufacturer's mounting instructions and verify the swivel mechanism operates freely and locks into position as required before applying workpiece clamping forces.

Usage recommendations

Use bolts and washers suitable for your bench material and expected load; check and retighten mounting hardware periodically. Keep the swivel mechanism clean and lubricated to maintain smooth rotation and reliable locking. Inspect the base and mounting points for signs of wear or loosening before heavy use.
