KASTFORCE KF5007 4 Inch Vise Mount Metal Brake Bender Attachment – 14 Gauge Steel / 1/8 in Aluminum

Expand your metal bending capabilities with the KASTFORCE KF5007

The KF5007 is a compact, 4 inch wide attachment designed to work with a 4 inch or wider vise, turning your existing setup into a capable metal brake. It’s built to handle common fabrication tasks with a focus on precision and ease of use, so you can tackle small brackets, channel bends, and custom fittings with confidence.

Designed for versatility, this attachment accommodates different materials and bend needs without requiring a full workstation upgrade. The device supports steel up to 14 gauge (2 mm) and aluminum up to 1/8 inch (3 mm), giving you flexible options for projects ranging from shop upgrades to hobbyist builds. The inclusion of removable hardened dies provides practical options for different radii, helping you achieve consistent bends when multiple parts are needed.

Key features at a glance

• 4 Inch (100 mm) width—fits on a 4 inch or wider vise for a broader bending footprint
• Max capacity: steel up to 14 gauge (2 mm) and aluminum up to 1/8 inch (3 mm)
• Removable hardened finger dies in 1 inch, 1 inch, and 2 inch sizes for flexible radii
• Vise mount with magnets for easy removal and reattachment; note that the vise is not included

In practice, you’ll notice the tactile feedback of precise metal forming, a clean edge after each bend, and a straightforward workflow that reduces setup time. The magnetized mounting simplifies changes between tasks, helping you keep projects moving even as you switch between materials and bend radii.

Practical use cases

• Fabrication of brackets and light steel frames with repeatable bends
• Small-diameter bends in aluminum components for prototyping or repair work
• Custom metal profiles for DIY projects, hobby builds, or shop upgrades

Overall, the KF5007 offers a practical upgrade for makers and technicians who want more bending flexibility without a full brake system. The combination of width, material capacity, and removable dies supports a variety of common fabrication tasks while keeping installation simple and unobtrusive.
