This 4-piece set provides multiple radii options for planishing and shaping curves. With a 22 mm stem diameter, the steel dies are CNC machined and hardened to 45-50 HRC, ensuring long service life in demanding shops. The included sizes enable forming a range of contours, from tight curves to broader arcs, making it versatile for various sheet metal tasks.
Key features:
– 4 steel dies included
– Stem diameter: 22 mm
– Radii variations: suitable for different contours
– Hardened steel with precise machining
Ideal for forming and smoothing dent repairs, edge work, and finishing large flat areas. Pair with a compatible planishing hammer for controlled shrink and bend operations that minimize distortion.
Louderlun 4 Piece Planishing Die Set (Alternative Radii)
This is another 4-piece Louderlun set featuring a different selection of radii, optimized for diverse planishing needs. The dies are constructed from hardened steel (45-50 HRC) and CNC machined for accuracy. The 22 mm stem diameter ensures consistent seating in compatible planishing hammer systems.
Key features:
– 4-piece steel die set
– Stem diameter: 22 mm
– Hardened steel, CNC machined
– Radii variety for multiple forming scenarios
Use cases include refining curved surfaces, smoothing planish patterns, and shaping metal edges with reduced risk of tearing or cracking under compression.
Louderlun 4 Piece Planishing Die Set (Small Radii)
This set features four small-radius dies designed for tight detailing and delicate shaping. The dies are manufactured from hardened steel (45-50 HRC) with CNC precision for repeatable results. The 22 mm stem diameter aligns with a wide range of planishing hammers, offering a compact solution for intricate dent work and edge finishing.
Key features:
– Four dies with small radii
– 22 mm stem diameter
– Hardened steel, CNC machined
– Suitable for precision finishing and detailing
Hteedy SS-16 Metal Shrinker Stretcher Set
The SS-16 set is a pneumatic planishing shrinker and stretcher combination designed for industrial sheet metal work. It uses a 2-in-1 approach, offering shrinking, forming, and bending capabilities with interchangeable anvils (1”, 2”, 3”). The construction emphasizes durability, corrosion resistance, and stability during operation. It operates via foot pedals and a handwheel with an adjustable air pressure range of 50-100 PSI.
Key features:
– 2-in-1 shrinking and forming tool
– Interchangeable anvils (1”, 2”, 3”)
– Pneumatic power with manual control
– Heavy-duty construction for industrial use
Applications include deep forming, precise shrinking, and thinned-area restoration on larger panels. This kit is suited for shops needing a robust, all-in-one solution for sheet metal finishing tasks.

It provides a practical tool length of approximately 295 mm, with a head width of 114 mm and a face diameter of 41 mm. The spiral face design is intended to distribute force evenly for consistent shrinking, making it a capable option for metal shaping and finishing tasks in a workshop environment.
Martin 153SFG Round Face Shrinking Hammer
This Martin model features a fiberglass-handled shrinking body hammer with a round face and a 1-9/16″ face diameter. It’s designed for finishing and controlled shrinking, offering an ergonomic grip and durable construction suitable for repeated use in metal finishing workflows.
Buying Guide: Key Considerations For Shrinking Dies And Planishing Tools
- Compatibility: Check shank diameter and compatibility with your planishing hammer. 16 mm (5/8”) is a common size for compact power hammers, while larger kits use 22 mm stems or universal interfaces.
- Material and Hardness: Look for hardened steel in the 45-50 HRC range for durability under repeated shrinking and forming tasks. CNC precision improves repeatability and fit.
- Radii and Sizes: Multiple radii options enable forming both tight curves and broad arcs. Evaluate whether you need radii sets for detailed work or larger panels.
- Power vs. Manual: Pneumatic kits (like Hteedy) offer consistent force with adjustable PSI, useful for repetitive work. Manual tools benefit from control and lower maintenance.
- Durability and Build: Steel dies with proper surface treatment resist wear and corrosion in workshop environments. Consider sets with protective coatings or reinforced frames.
- Ease of Use: Quick-change interfaces and clear labeling help streamline workflow. Ergonomics, especially on hammers with longer sessions, reduce fatigue.
- Maintenance: Regular inspection for dings, cracks, or wear; replace worn dies to preserve workpiece quality and prevent tool damage.
- Application Scope: Choose kits that cover dent repair, edge finishing, and general forming to maximize versatility in one purchase.
- Brand Support and Warranty: Reputable brands with responsive support can be valuable for replacements and compatibility questions over time.
In selecting shrinking dies and planishing accessories, prioritize compatibility with your existing hammer, the range of forming radii you need, and the durability to withstand daily shop use. For professional shops, investing in a mix of dedicated dies and a pneumatic shrinker/stretcher can provide a flexible, durable workflow. For hobbyists, a compact set with several radii and a reliable manual hammer may suffice, balancing cost and performance.
