Drill Press/Bench Clamps feature technology that enables the jaws to automatically adjust to and grip different size objects quickly without manually fine tuning the adjustment. Set the desired clamping pressure, and the jaws apply that pressure to the different sizes of material - no continuous adjustment needed for unprecedented convenience! Dual application with mounts for Workbench T-Track and for Drill Press/Table machines, this clamp fits all your needs. Comfortable Soft Grip and removable rubber tip for soft materials round out the features. One-hand clamping operation frees up your other hand to hold material for fast easy setup. Jaw range 4.5", clamping force 25-250 lb.
