The Industrial-Grade Bench Vise from Olsa Tools is designed to withstand the toughest jobs. The S45C steel is forged to extreme high pressure of 90,000 psi, resulting in a vise that is significantly stronger than cast iron and ductile iron alternatives, the company says. The industrial-grade vise can handle a clamping force of up to 9,900 lbs. and is available in 4", 5", 6", and 7" jaw widths. It also includes the mounting hardware and a set of protective rubber jaw covers that attach and detach easily which are ideal for getting a firm grip on delicate materials.
