CNC-machined in-house from premium USA sourced steel, heat treated for long service life, and backed by a Lifetime Warranty, our dimple dies are designed to produce clean, consistent dimples that add strength, reduce weight, and give fabricated parts a professional motorsports appearance.

Whether you're building a race car, drift car, drag car, circle track car, trophy truck, prerunner, Ultra4 buggy, rock crawler, hot rod, street machine, UTV, motorcycle, aircraft, or custom chassis, TMR dimple dies help transform flat sheet metal into lightweight, rigid structural panels.

Available individually or in complete sets, including our popular 5-Piece Fabricator Set, TMR dimple dies are trusted by professional fabricators and serious DIY builders across North America.

Why Use Dimple Dies?

A properly formed dimple does much more than improve appearance.

By flanging a hole, a dimple die increases the rigidity of sheet metal while removing unnecessary weight. This allows builders to create stronger, lighter panels for race vehicles and fabricated components without sacrificing structural integrity.

Benefits include:

• Increased panel stiffness and rigidity
• Reduced overall vehicle weight
• Professional motorsports appearance
• Cleaner, stronger fabricated panels
• Improved strength around cut holes
• Consistent, repeatable results

For these reasons, dimple dies have become a staple tool in race shops, fabrication shops, and custom chassis construction.
