Chicago Dreis & Krump Sheet Metal Hand Brake

Standard metal bending or Box & Pan brake, floor mounted or portable benchtop.
A sheet metal hand brake is designed for bending sheet metal. It uses 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 agle. 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 clamping bar "finger" at each end of the box since the clamping bar is divided up into many assemblies called "fingers". Extension Fingers are used to form inside corners with a return flange across the top. Open End Fingers are used to form tubes of triangular, square, rectangular, or tapered shape. 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 machine with limited uses. Since Dreis & Krump 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, efficiency, dependability, or options, then or now. Scroll down to see our selection. Options include a handwheel back gauge, extra small insert bar, radius formers, open end fingers, extension fingers, and radius fingers.

STANDARD SHEET METAL HAND BRAKE: See chart below.

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 don't offer:
• Handwheel Back Gauge - 25 inch travel (see below)
• Insert Bar - 1/4 inch (for closer offset bends)
• Radius Formers - for forming gutters, mouldings, etc.

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 don't offer:
• Handwheel Back Gauge with 25" travel (see below)
• Extension Fingers (to form 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)
• Insert Bar - 1/4 inch (for closer offset bends)
• Radius Formers - for forming gutters, mouldings, prototypes, from thin sheet metal.
