Our metal benders are available in standard straight bending or Box & Pan brake style, floor mounted or benchtop and even push button control with hydraulic power. A sheet metal hand brake normally bends sheet metal by using a hinged clamping bar to hold the metal down against the bed. A hinged bending "leaf" is lifted to fold the metal around the fulcrum point of the clamping bar to the desired angle which is controlled using a stop rod.
A box and pan brake machine is needed to avoid having the metal hit against the clamping bar when the 3rd and 4th sides are being bent. This is done by removing a "finger" from the clamping bar at each end of the box since the clamping bar is divided up into many sub-assemblies called "fingers".

Picture of how to make a reinforced sheet metal Box or Pan shape. Consider buying our optional Extension Fingers to make this easier.

Chicago Dreis & Krump offers more machine options: Extension Fingers are used to form inside corners with a return flange across the top. See pictures above and down below. Open End Fingers are used to form tubes of triangular, square, rectangular, or tapered shape. See picture below. Radius Nose Bars are available for bending your metal around a radius, which is useful for bending aircraft aluminum. See picture below. An insert bar is used to form offset ("zig-zag") bends close together. Radius formers are attachments used for hand forming of thin sheet metal shapes such as gutters, architectural mouldings and prototype modeling.

Don't settle for a poorly engineered machine. Since the Chicago Dreis & Krump Company pioneered the standard sheet metal bending Hand Brake in the year 1899, lots of people have copied their designs, but none have been able to surpass their quality, engineering, dependability, or options, then or now. Available options include a handwheel back gauge, extra small insert bar, radius formers, open end fingers, extension fingers, radius nose bars, and even push button hydraulic powered metal bending.

If you dont want use the strength of your back and arms to manually bend metal on a Hand Brake machine, we offer a push button electric-hydraulic power leaf brake machine to do the same work.

STANDARD SHEET METAL HAND BRAKE:

Chicago Dreis & Krump heavy duty machinery construction. Designed for accurate and economical bending of standard and special design forms. Ideal for bending mild steel with a 1 inch minimum flange to the rated capacity of the machine. Capable of 1/4 inch reverse bends on lighter metal. Even usuable for occassional hemming.

Options most hand brakes can't offer:
• Handwheel Back Gauge - 25 inch travel to measure and square up your metal (see below)
• Insert Bar - 1/4 inch (for closer offset bends)
• Radius Formers - for forming gutters, mouldings, prototypes, etc, from thin sheet metal.

BOX & PAN SHEET METAL HAND BRAKE: See chart below.
Incorporates all of the outstanding features of the standard hand brake plus removable, sectioned fingers that can bend any length of metal from 3 inches long to the full length of the machine. Boxes and pans can be up to 6 inches deep. A very versatile well built Chicago Dreis & Krump machine.

Options most hand brakes can't offer:
• Handwheel Back Gauge with 25" travel to measure and square up your metal (see below)
• Extension Fingers (to form rigid inside corners with a return flange across the top)
• Open End Fingers (to form tubes of triangular, square, rectangular, or tapered shape)
• Radius Nose Bars up to 1.5" (great for aluminum aircraft work)
• Insert Bar - 1/4 inch (for closer offset bends)
• Radius Formers - for forming gutters, mouldings, prototypes, from thin sheet metal.

Add an optional Chicago Dreis & Krump Back Gauge:

Who says a hand brake can't have sophistication?
Tired of always using a tape measure to mark lines that must be lined up with the nose bar? This back gauge has a 25 inch travel with a inch/cm scale so it is a must for those who want a labor saving, time saving, accuracy improving hand cranked back gauge to speed up production and improve quality. It measures where your metal bend will be and it squares up your metal to the machine.

Optional Back Gauge attaches to the new Chicago Dreis & Krump sheet metal brake machine

Magnetic Box and Pan Sheet Metal Brake

A strong 6 ton magnet in the bed is activated by foot pedal or push button control to hold down a mild steel clamping bar of almost any configuration across the bed width or bed length. The sheet metal is pinned between the magnetic mild steel clamping bar. The bottom bending leaf is lifted to make the bend. The steel clamping bar can be made of straight bars (of various widths for tight boxes) for straight bends or segmented clamping bars for box and pan applications of any other configuration such as totally enclosed boxes, triangles, alternate bends on varying planes, round items such as scrolling applications, and much more. Great for bending mild steel sheet metal, stainless steel, aluminum, coated materials, and heated plastics. The bottom leaf’s bending extension can be removed for the tightest bends. The scaled stroke angle control can be set for repeat bends. Parts supports and adjustable back gauge for production runs, east to use gap adjustments on the clamping bars for different sheet metal thicknesses.
