If you need to make clean bends in flat steel without buying a floor-standing brake, a press brake attachment can turn a hydraulic shop press into a bending station. The catch is that two very similar attachments for that job sit apart in price. Both are sold as new items, so condition doesn't separate them. One names a specific tonnage range; the other is described more generally for hydraulic shop presses. The decision comes down to whether the higher price buys anything you actually need.
Quick Verdict
If your press matches the tonnage range in the lower-priced attachment's title, the lower-priced attachment is the sensible buy. It handles the same bending tasks as the higher-priced alternative for a noticeably lower price. If you want a compatibility description that stays general, the higher-priced attachment is the one that matches that preference. For a buyer with a press in that same tonnage range, the extra cost doesn't add a functional benefit.
Press Brake Attachments Compared
The table below focuses on the specs that matter most for a shop-press bending attachment.
| Feature | 12-inch attachment for 12-20 ton presses | Press brake attachment for hydraulic shop presses |
|---|---|---|
| Price | USD 59.27 | USD 107.33 |
| Max. bending length | 12 in | 12 in |
| Max. bending thickness | 3/16 in | 3/16 in |
| Bending angle | 90° | 90° |
| Material | 45# steel | 45# steel |
| Finish process | Plastic spraying, blackening | Plastic spraying, blackening |
Where the tonnage-specific attachment wins
The $59.27 attachment is the lower-cost route to a shop-press bending attachment. Its title also states a specific compatibility range: 12-20 ton hydraulic shop presses. If you already know your press fits that range, this title gives you that match in the name itself. The package description also names a single press brake attachment, so you know the purchase is straightforward.
Where the hydraulic shop press attachment wins
The $107.33 attachment keeps the compatibility wording general. It's described as an attachment for hydraulic shop presses, with no tonnage window. That makes it the more comfortable choice if you don't want to self-identify a tonnage range before you've looked through the details. That general wording can also be easier to work with if you plan to use the attachment on different presses, since the title doesn't lock you into one tonnage number.
Product Notes
12-inch press brake attachment for 12-20 ton hydraulic shop presses
At $59.27, this is the more affordable way to add a bending attachment to a hydraulic shop press. The title is specific: it's for 12-20 ton hydraulic shop presses, which makes it easy to match against the press you already own. The package is described as including one press brake attachment. The material is 45# steel with a plastic-sprayed and blackened finish. The main limitation is the bending capacity: it maxes out at 3/16-inch steel, so thicker material is beyond what this attachment is built for. If your press falls outside the 12-20 ton range, the tonnage-specific wording becomes less useful.
Press brake attachment for hydraulic shop presses
The $107.33 attachment costs noticeably more, but the core bending specs match the lower-priced model: 90° angle, 12-inch max length, 3/16-inch max thickness, and 45# steel. Its advantage is the compatibility wording in the title: it simply says "for Hydraulic Shop Presses" without naming a tonnage range. That's useful if you don't want to match a specific press size. The downside is the price: $107.33 buys the same bending envelope as the $59.27 model. For a buyer whose press already fits the 12-20 ton range, the extra money doesn't bring a functional benefit beyond the broader wording.
Final Choice by Use Case
- If your press matches the tonnage range in the lower-priced attachment's title, choose the tonnage-specific attachment and keep more money in the shop.
- If you prefer a description that doesn't pin compatibility to a tonnage window, choose the press brake attachment for hydraulic shop presses.
- If you need to bend thicker material than both of these allow, you'll need to look beyond these two attachments.
