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)
