CNC machined in-house from the highest grade domestic materials available, TMR Customs Dimple Dies for Knockout Punches are a tool that will last you a lifetime, at a price that won't break the bank!

Dimple dies/flared hole dies are used to add strength and rigidity to sheet metal panels. 

Each die starts life as a solid billet of high grade domestic steel. We CNC machine each dimple die to exacting tolerances in-house on our Mazak CNC Turning Center. After the machining is complete, each die is sent to a dedicated heat treat facility and hardened to the optimal hardness level. After heat treating, each die is sent to a dedicated coating facility where they are coated not only for good looks, but also to protect your investment in a high quality tool.

WARRANTY: To guarantee these are the highest quality dimple dies on the market we stand behind them with our LIFETIME WARRANTY!

I picked up a set of these to go with a greenlee knockout set I already have. They work awesome! These are a real fast way to dimple die holes, I could even do some right on the car. Thanks TMR! (Posted on 6/6/2017)

Product Q&A

What gauge material will this punch? Steel, aluminum, and stainless?
Hi Ricky. The material and material thickness limitations are based on the knockout set that you use. We've used the Harbor Freight and GreenLee units on mild steel, chromoly, stainless and aluminum with good results. Hope that info helps!
