The following sections highlight each attachment’s key features, compatibility, and practical considerations to help you determine which model aligns with your typical material and project needs.
12″ Press Brake Attachment for Standard 12/20 Ton Presses
This Generic press brake attachment provides a practical option for hobbyist and light-duty fabrication tasks. It attaches to most standard hydraulic shop presses and supports bending operations up to 12 inches in length. The upper die mounting cup features an inside diameter of 1-7/8 inches (48 mm), supporting common tooling sizes and enabling straightforward setup for simple bends. It’s best suited for aluminum and mild steel at modest thicknesses and can help you add small, precise angles quickly on your existing press.
12″ Fringer Press Brake Attachment for 20 Ton Presses
The Quaintfab Fringer press brake attachment is designed for 20-ton hydraulic presses and includes multiple finger sizes (1″, 2″, 2″, 3″, 4″). This versatility supports various bend radii and sheet thicknesses, with an upper die mounting cup diameter of 1-7/8 inches. It offers a robust construction suitable for hobbyist to light commercial use, helping you achieve precise bends while maintaining stable operation on a heavier press frame.
KASTFORCE KF5017 Press Brake Attachment
The KASTFORCE KF5017 attaches to most standard 12 to 20 ton hydraulic shop presses and offers a defined bending capacity with a 12″ max length and a 3/16″ maximum thickness. This attachment emphasizes rigidity and ease of use, making it suitable for repeated bends and repetitive fabrication tasks. It’s a practical option for metalworkers who need consistent results without upgrading to a full bench-mounted brake.
Noliven 12″ Press Brake Attachment Kit
The Noliven 12″ kit emphasizes heavy-duty construction with a dual spring design to minimize vibration and improve bending stability. Built for 12–20 ton presses, it supports bends up to 12 inches long and up to 3/16 inch thick material. The dual-spring system and precision-tuning locking screws help retain bend angles with high repeatability, making it a solid pick for long-running fabrication projects.
Eastwood Press Brake Attachment for 12/20 Ton Presses
Eastwood’s attachment focuses on precision and versatility, capable of bending up to 12 inches with a 90° bend angle in mild steel and aluminum up to 3/8 inch thick. It attaches to most standard 12 or 20 ton presses, providing an accessible option for projects requiring moderate thicknesses and tighter tolerances. For users prioritizing accuracy and repeatable results, this attachment aligns with dependable, shop-friendly performance.
Buying Guide
- Compatibility: Confirm your press’s tonnage, bed dimensions, and mount type to ensure the attachment fits without modification.
- Bend Length and Thickness: Match the maximum bend length and material thickness to your typical projects (12″ length; commonly up to 3/16″ to 3/8″ thickness).
- Durability: Look for high-grade steel (e.g., 45# or equivalent) and reinforced bases to minimize deflection and vibration under load.
- Stability and Base Design: A thick, wide base improves stability and reduces wobble during bending operations.
- Vibration Control: Dual-spring or other vibration-damping designs help maintain bend accuracy and operator comfort.
- Ease of Setup: Tooling compatibility (upper die cups, finger sizes) and straightforward clamping reduce setup time for repeated tasks.
- Manufacturer Support: Consider brands with clear installation guidance and replacement parts availability for ongoing maintenance.
When selecting, balance budget with the need for reliability and repeatable accuracy. For users who frequently bend thinner materials or require quick project turnaround, a lighter-duty attachment with solid stabilization may outperform a heavier, more complex unit in casual shop settings. Conversely, professional shops bending thicker stock at higher volumes will benefit from reinforced bases and robust spring systems to sustain performance over time.
