Accuracy guarantee

In order to ensure reliable use of our carbide punches by the customers, each and every product is measured both at the time of manufacture and also again after being left in a thermostatic chamber for a certain period of time after manufacture. These measurements are listed in the Quality Guarantee Certificate which is attached to the product.

Quality Guarantee Certificate


*The Quality Guarantee Certificate is attached to carbide products only. The accuracy standards for steel products differ from the above. For further details, refer to the relevant pages.
