We have been using your Rocklinizer and have been quite pleased with this Rockhard application equipment. The product has been very dependable and perfect for obtaining a better gripping surface for our collets.

We have recently purchased (3) new machines giving us a total of 6 machines. This purchase was required because of our volume of work and Rocklin was chosen because of our previous success with current equipment.

Thanks for providing a good product.

The Rocklinizer is one of the best investments I have ever made for use in our shop.

We have used it for hardening bearing surfaces, cutting tools, dimensional build-ups, and wear surfaces, just to name a few. It is a great money and time saving device.

If I told you how much money and time it has saved me, you probably wouldn’t believe it. I purchased another for our Flagstaff, AZ facility and they’re more than satisfied with its performance. Thanks for providing us with a great product.
