The hydraulic shear is used to cut sheet metal to accurate dimensions quickly. This is a powered machine that uses a blade to shear the metal with hydraulic force. It is operated by a foot pedal so the operator’s hands are away from the blade when shearing ope...

The turret punch provides a fast, accurate and flexible method of punching holes in sheet metal up to 16 gauge thickness. Twelvereplaceable punch and die sets are located in two turrets, which can be positioned by a special spanner wrench that synchronizes the...

The corner notcher is a versatile, heavy- Handle duty bench tool for shearing, notching and piercing work. This tool is used for making specific angled cuts in sheet metal. Notches of more than 90° can be accomplished in two operations. The shearing capacity o...

The straight or slitting shear is a bench tool used to make manual straight cuts in sheet metal. It consists of two -blades that shear material when a lever is pulled and the blades come together.  The shearing capacity of this tool is 16 gauge sheet. TODO i...

A finger brake, also called a box-and-pan brake, is used for making bends in sheet metal. The brake consists of a flat surface onto which the material is placed, and a clamping bar which will come down and hold the material firmly during the bend. The clampin...

A spot welder is part of a metal joining process in which parts to be welded are held together under pressure by electrodes. Current is then applied and the resistance between the 2 sheets of metal causes a bonding only at the contact point and creates a small...

A slip roll uses three rolls to form light gauge sheet metal into curves and pipe. The two front rollers of a slip roll, or pinch rollers, are used to feed the sheet metal into the rear bending, or forming, roller that places the arc in the sheet metal. By adj...
