Irwin 1ZR Record Heavy Duty 3″ Mechanics Vise

The IRWIN Record 1ZR 3″ mechanics vise is a compact, shop-ready bench vise designed for reliable clamping on metal and wood projects. Its body and sliding jaw are manufactured from close-grained grey cast iron and machined on all friction surfaces, so the jaws track smoothly and stay aligned under load. A long-barreled, dovetailed nut and aligned mainscrew provide dependable travel with every turn, while the twin-start acme thread moves from fully closed to fully open with less winding. The hardened steel jaws are replaceable, extending the service life of the vise over years of use.

For daily bench tasks—cutting, filing, drilling, tapping, light straightening, and assembly—the 1ZR delivers more than 3,000 lb of clamping force in a small footprint. A fused steel handle is engineered to bend before the vise is overstressed, and a safety stop prevents the slide from coming free at full extension. An integrated anvil supports quick peening and bracket work without switching stations. With a swivel base for easy positioning, this 3-inch bench vise fits repair benches, mobile carts, and compact worktops where space is tight but holding power matters.

Markets

• Automotive & Fleet Repair: Secure grip for cutting, tapping, press-fit prep, and bracket work.
• Fabrication & Machine Shops: Everyday clamping for layout, deburring, and drilling.
• Construction & Renovation: Reliable bench holding for metal and wood components.
• Maintenance, Repair & Operations (MRO): Durable shop vise for facilities and industrial sites.
• Municipal Shops & Utilities: Consistent performance for public works and fleet service benches.
• Trade Schools & Training Centers: Teaches safe, repeatable clamping with serviceable jaws.

Technicians and fabricators get predictable clamping pressure and smooth screw action that makes delicate work—like tapping and filing—feel controlled. The swivel base lets repair crews set a better line of sight for cutting or drilling without remounting the workpiece. Maintenance teams value the replaceable hardened jaws and the fused steel handle that bends before the vise is overstressed, helping protect both tool and bench. In training labs, the safety stop helps keep the slide in place at full opening, and the twin-start acme thread moves quickly for faster setups between students. For advanced DIY users in small shops, the 3-inch jaw width and 4-1/4″ opening cover most bench vise tasks while the integrated anvil handles quick peening or straightening jobs without leaving the vise.
