Need a clean 90° bend in a piece of mild steel or aluminum without buying a full-size press brake? If you already own a 12 or 20 ton hydraulic shop press, the Eastwood Press Brake Attachment is a compact way to add bending capability. At USD 299.99, it is priced well below a dedicated floor-model brake, but you need to make sure your workpiece sizes and press ram fit its specs.
Quick verdict
The Eastwood Press Brake Attachment turns a standard 12 or 20 ton hydraulic shop press into a press brake for mild steel and aluminum up to 3/8 inch thick and 12 inches wide. It handles bends up to 90° and has a maximum bending length of 12 inches. If that covers the parts you build-floor reinforcement channels, ribs, pickup bed floor sections, bedside panels, inner fender structures, suspension brackets, engine and transmission mounts-this attachment is a practical way to get the bends without adding another large machine to your shop.
What stands out
The attachment is designed for most standard 12 or 20 ton hydraulic shop presses. The upper die mounting cup has an inside diameter of 41mm, so it is built around a common ram size, but it is still a specific fit that needs to match your press. The overall dimensions are 14.5 inches wide by 7.5 inches deep by 9.25 inches high, which gives you a sense of the footprint on the press bed.
The bending envelope is clearly defined: widths up to 12 inches and thicknesses up to 3/8 inch in mild steel and aluminum. That covers a lot of automotive and fabrication panels, and the 90° bend angle handles the most common sheet metal joints. The design also supports creating complex shapes beyond simple straight bends, like corrugated truck bed floors and inner fender structures, all with one accessory tool.
Who it suits
This attachment is a good fit for someone who already has a 12 or 20 ton hydraulic press and does occasional or regular bending of flat stock. It is also suitable for a home hobbyist or small fab shop that does not have floor space or budget for a dedicated press brake. Because it is not a full machine, it makes sense when you want to add bending to an existing press rather than buy a new piece of equipment.
Meaningful trade-offs
The main trade-off is the size limit. If you frequently bend pieces longer than 12 inches, this attachment will not handle them. The 3/8-inch thickness limit also means you cannot use it for heavier plate stock. Another trade-off is the mounting cup fit: the 41mm inside diameter is specific, so you need to confirm that your press ram uses that size before relying on it. Also, the item carries a California Prop 65 warning for cancer and reproductive harm, which is something to be aware of if you are sensitive to prop 65 notifications.
Eastwood Press Brake Attachment For Standard 12/20 Ton Hydraulic Shop Presses
This Eastwood attachment provides a 12-inch maximum bending length, 90° bends, and supports mild steel and aluminum up to 3/8 inch thick. Choose it when you need to make formed parts like brackets, channels, and panels without adding a standalone press brake. The main limitation is that your press ram must fit the 41mm mounting cup inside diameter, and you are restricted to the 12-inch width and 3/8-inch thickness maxima.
Bottom line
If your bending tasks fit within 12 inches wide, 3/8 inch thick, and 90°, the Eastwood Press Brake Attachment is a straightforward way to get those bends from a press you may already own. At USD 299.99, it is a focused accessory rather than a full machine, so the decision really comes down to whether the size envelope and mounting cup fit work for your projects.
