For buyers seeking to convert a standard 12–20 ton hydraulic shop press into a capable metal bending tool, a hydraulic press brake attachment is essential. These attachments let you form precise bends without a dedicated press brake. They’re ideal for hobbyists, small shops, and DIY fabricators who need occasional, accurate 90° bends and consistent results. The following five products are selected for versatility, compatibility, and measurable bending capacity across common steel gauges. Use the comparison table below to quickly weigh the core specs at a glance.
| Product | Maximum Bend Width | Material Thickness (Max) | Angle Range | |
|---|---|---|---|---|
| KASTFORCE KF5017 | 12 inches | 3/16 inch | 0°–90° | 12–20 Ton Hydraulic Shop Presses |
| 12 inches | Up to 3/8 inch | 0°–90° | Standard 12/20 Ton Presses | |
| Noliven Kit | 12 inches | 3/16 inch | 0°–90° | 12–20 Ton Presses |
| AELIVET 12″ Attachment | 12 inches | 3/16 inch | 0°–90° | 12–20 Ton Presses |
| BOPRCSH 12″ Attachment | 12 inches | 3/16 inch | 0°–90° | 12–20 Ton Presses |
KASTFORCE KF5017 Press Brake Attachment
The KASTFORCE KF5017 offers universal compatibility with most standard 12–20 ton hydraulic shop presses and a maximum 12-inch bending length. It supports bending up to 3/16 inch material, making it suitable for light-to-moderate sheet metal tasks. Best for workshops that need a straightforward, dependable conversion without extra features or frills. Choose this if you want a compact, reliable option with predictable performance. Caution: verify your press mounting pattern and ensure stable setup to avoid misalignment during heavy bends.
Eastwood Press Brake Attachment
Eastwood’s attachment is designed to produce accurate, variable-length bends with up to 12 inches width and materials up to 3/8 inch thick. It attaches to most standard 12/20 ton hydraulic shop presses and is positioned as a general-purpose option for metal fabrication projects. Best for users who require slightly thicker bends and a familiar Eastwood-brand option. Better for projects needing higher-thickness capability than some entry-level units. Limitation: the data notes 3/8 inch max thickness; verify your exact material before bending beyond this range.
AELIVET 12″ Press Brake Attachment
The AELIVET attachment is designed for 12–20 ton presses, offering a 12″ bending width and 0°–90° adjustable angles. It emphasizes industrial-grade steel construction with protective coating for durability in demanding environments. Best for users seeking a robust, durable option with clear 12″ width and strong bending range. Choose this if you prioritize high durability and consistent 90° bends. Caution: ensure proper alignment and secure mounting to prevent slippage during use.
BOPRCSH 12inch Press Brake Attachment
BOPRCSH offers a ready-to-use press brake attachment for 12-inch width with a maximum bend thickness of 3/16 inch. It emphasizes a high-strength 45# steel build with protective coating for longevity. Best for users seeking an easy, direct-install solution with straightforward operation. Avoid this if your projects routinely exceed 3/16 inch thickness or require thicker material bending without upgrading to a heavier setup.
12″ Press Brake Attachment For Standard 12/20 Ton Hydraulic Shop Presses
This attachment concentrates on maximal thickness and width capacity, with bending widths up to 12″ and thickness options including 3/16″, 1/4″ and 5/16″ depending on the die setup. Best for versatile small- to medium-scale projects where varied thicknesses are common. Consider this if your typical work involves multiple sheet sizes and you want a single tool capable of several bend limits. Caution: confirm the maximum material thickness for your chosen configuration before bending for extended periods.
Buying Guide: Key Considerations For Hydraulic Press Brakes
- Compatibility: Look for universal mounting to standard 12–20 ton presses and ensure the attachment’s throat and mounting cup dimensions match your press model.
- Bend Width And Thickness: Choose a unit with a 12″ bend width and a maximum thickness that covers your typical materials, commonly 3/16″ to 3/8″ for mild steel.
- Angle Range: A 0°–90° capability is standard and sufficient for most sheet metal tasks; verify any limited angle allowances or step angles.
- Durability: Steel construction with protective coatings increases longevity in workshop environments and reduces wear on repeated bends.
- Ease of Use: Features such as dual-spring dampening, precise locking screws, and straightforward installation save time and improve repeatability.
- Stability: A reinforced base and vibration resistance help maintain accuracy under higher bending loads.
- Safety: Ensure secure mounting and confirm clearance around the workpiece to prevent pinch points and misalignment during operation.
Frequently Asked Questions
- What is the typical maximum bend angle for these attachments? Most units offer 0° to 90° bends for standard sheets.
- Do these attachments require the press to be dedicated? They are designed to attach to standard 12–20 ton hydraulic presses and not require a separate brake.
- Can I bend aluminum with these tools? Yes, many units bend mild steel and aluminum within their specified thickness ranges.
- Is mounting hardware included? Attachments generally specify mounting compatibility; verify whether your purchase includes all necessary mounting components.
- How thick can I bend safely? Most common models support up to 3/16″ or 3/8″ depending on the unit; exceed these limits risks damage or reduced accuracy.
- Which attachment is best for thick metal work? For thicker sheets, choose units supporting up to 3/8″ thickness and verify your press power and die dimensions.
