| Trick-Tools Bend Press Kit | Trick-Tools | Benchtop kit with 4-way V-die for flexible projects |
These selections cover a range of needs—from general fabrication to dedicated V-die and urethane protection options—while remaining compatible with common 12/20-ton hydraulic presses. All options are designed to reduce marring and improve repeatability across multiple projects.
Eastwood Press Brake Attachment for Standard 12/20 Ton Hydraulic Shop Presses
Precision engineered to produce accurate, variable-length bends with 90-degree angles in mild steel and aluminum. Suitable for widths up to 12 inches and thicknesses up to 3/8 inch. Designed to attach to most standard 12 or 20 ton hydraulic shop presses, this attachment emphasizes consistent results and ease of use in shop environments.
Prolinemax 12″ Press Brake Bender V-Block Attachment
Attaches to most standard 12 or 20 ton hydraulic shop presses. Provides a 12″ bending length with a bending thickness around 3/16″ (5 mm, 4 gauge). The V-block design supports consistent 90-degree bends and helps stabilize workpieces during operation.
Trick-Tools Bend Press 4 Way V-Die Tooling
4-way V-die tooling crafted from 4140 tool steel for durability when bending up to 3/16″ steel. Features openings at 1/2″, 3/4″, 1″, and 1-1/2″ for tight radii on thin materials, with a total width of 10 inches for stable operation and versatility in small shop setups.
Maasechs Press Brake Urethane Die Protection Film (4″ x .012″ x 100′)
Urethane die protection film protects stainless steel parts and pre-coated parts by reducing pressing marks at the bend. It’s reusable, easy to cut to length, and helps streamline workflows by avoiding additional polishing steps after bending.
12″ Press Brake Attachment for Hydraulic Shop Press (12-Ton & 20-Ton Compatible)
Heavy-duty 45# steel construction with anti-rust coating ensures durability in daily use. Delivers precise 90° bends up to 12 inches in length and supports material thickness up to 3/16″. Compatible with standard 12-ton and 20-ton hydraulic presses, with secure mounting screws and a wide base for stability during operation.
Quaintfab 19.5″ Press Brake Attachment for 20 Ton Hydraulic Presses
This attachment is designed for presses with at least 22″ between uprights, offering 22″ width, 7.5″ depth, and 10″ height. It’s suited for larger projects and supports a variety of die configurations, expanding the range of possible bends beyond compact 12″ options.
Buying Guide
Key purchase considerations for press brake attachments include compatibility, capacity, and die configurations. Compatibility depends on whether the attachment fits standard 12-ton or 20-ton hydraulic presses, as well as bolt patterns and mounting bases. Capacity concerns include bending length (often 12″ or 19.5″), maximum material thickness (commonly 3/16″ to 1/4″), and the maximum bend angle (typically up to 90°). Die configurations—V-die, 4-way dies, and protective films—affect the range of bend radii and surface protection during forming.
Material compatibility matters: tool steels and urethane films provide durability and protection, while protective films reduce marks on stainless steel parts. For larger or more complex projects, benchtop kits and 4-way dies extend versatility, enabling multiple bend styles without swapping tooling frequently.
Usage context matters as well. If you frequently bend thin gauge steel or aluminum, a compact 12″ attachment with a strong base and alignment features reduces setup time. For heavier, thicker workpieces, look for higher pull resistance, robust construction, and secure mounting to ensure repeatable results. Always confirm that the attachment is designed for your press’s tonnage, bed size, and mounting pattern to avoid compatibility issues.
