A Machinist Bench Vice 150mm is a sturdy clamping tool used to hold workpieces securely in place during machining, drilling, or other tasks in workshops. 150mm refers to the jaw width of the vice, meaning the vice can clamp materials up to 150mm wide. It is typically mounted to a workbench to provide stability during operations. The vice is designed with precision-machined jaws to hold metal, wood, or plastic securely while allowing for controlled work. It may include a swivel base for adjustable positioning, and the handle allows for easy tightening or loosening. This type of bench vice is commonly used by machinists, woodworkers, and mechanics for various tasks requiring accurate and firm clamping.
