Do you need a complete bending machine, or do you already own a 12-20 ton hydraulic shop press and just want to add bending capability? The four options here cover both paths: a full 51-inch, 50-ton hydraulic press brake bender and three 12-inch attachments designed for standard 12-20 ton shop presses. Your choice will come down to how much independent capacity you need, how thick the material is, and how much you want to spend. If you are starting from a bare shop floor, the all-in-one bender simplifies setup. If you already have a press, an attachment keeps your existing tool useful.
Quick take: If you want a ready-to-run bender with a 51-inch blade and 50-ton capacity, the two-cylinder electric press brake is the only complete unit in the group. If you already have a 12-20 ton hydraulic shop press, the three 12-inch attachments let you add 90° bending without buying a whole machine. Among those attachments, the Eastwood offers the thickest max bending capacity, while the two remaining attachments offer lower-cost entry points.
As a quick reference, here is how the four listed prices stack up:
| Product | Price | Price Bar |
|---|---|---|
| 51" x 1/4" Electric 50 Ton Hydraulic Press Brake Bender 2-Cylinder 3-Phase 220V | USD 7,749.99 | |
| 12" Press Brake Attachment for 12-20 Ton Hydraulic Shop Press Bending RedUS | USD 87.57 | |
| 12" Press Brake Attachment for 12-20 Ton Hydraulic Shop Press Bending Red | USD 59.27 | |
| Eastwood Press Brake Attachment For Standard 12/20 Ton Hydraulic Shop Presses | USD 299.99 |
Here's how the four options compare on the core bending specs that matter:
| Option | Type | Max Bending Thickness | Requires Existing Shop Press? |
|---|---|---|---|
| 51" Electric 50-Ton Press Brake Bender | Complete press brake | 1/4" | No |
| 12" Press Brake Attachment (RedUS) | Attachment | 3/16" | Yes |
| 12" Press Brake Attachment | Attachment | 3/16" | Yes |
| Eastwood Press Brake Attachment | Attachment | 3/8" | Yes |
Keep that distinction in mind: a standalone bender is a new machine, while an attachment is an accessory that extends the reach of equipment you already own.
51-Inch Electric 50-Ton Press Brake Bender
This is the only complete press brake in the set. It uses a two-cylinder hydraulic system with a 3-phase 220V motor and a 54-inch worktable, and its piston travel adds working depth that a simple attachment cannot match. The main trade-off is scale: it needs 3-phase power and a large footprint, and it ships as oversized freight. Choose it if you want a stand-alone bender and do not need to rely on an existing shop press.
12-Inch Press Brake Attachment (RedUS)
This attachment for 12-20 ton hydraulic shop presses uses 45# steel with a plastic spray and blackening process, bends to 90°, and has a max thickness of 3/16 inch. The package includes the attachment only, so your own hydraulic press is required to do the work. The limitation is that 3/16-inch max thickness puts it on the lighter side if you often bend thicker sheet. If you already have a press and want a compact 12-inch tool, this is a direct fit.
12-Inch Press Brake Attachment
This version spells out net weight, gross weight, max bending length, and max bending thickness. It follows the same 45# steel construction with a plastic spray and blackening finish, and it produces 90° bends. Like the other attachments, it cannot work on its own; it needs a 12-20 ton hydraulic press. For a shop that wants those numbers available before pairing it with an existing press, this is the version to look at.
Eastwood Press Brake Attachment
The Eastwood attachment is the only one with a named brand in the title. It is made for standard 12-20 ton hydraulic shop presses, has a 12-inch max bending length with a 90° bend angle, and offers a thicker max capacity than the other attachments. The unit carries a California Prop 65 warning that you should be aware of. The main limitation is that it still depends on your existing shop press, so it does not replace the big machine. If you need thicker 12-inch bending within an attachment, this is the one to weigh.
Final recommendations by use case:
- For a complete, stand-alone press brake: the 51-inch electric 50-ton hydraulic press brake bender at USD 7,749.99 is the only fully integrated unit in this set. It brings tonnage, blade length, and press frame together without needing a separate shop press.
- For a 12-20 ton shop press owner who needs maximum thickness: the Eastwood Press Brake Attachment at USD 299.99 lists the thickest max capacity among the attachments.
- For a 12-20 ton shop press owner who wants the lowest-priced 12-inch attachment: the 12" Press Brake Attachment for 12-20 Ton Hydraulic Shop Press Bending Red at USD 59.27 covers the basic 90-degree bending profile. The RedUS version at USD 87.57 is the same basic format if you prefer that listing.
