These reamers have given a night and day difference with their chip control. Thanks to all of you for following through and pushing delivery.

Thank you again for all your help. And I also appreciate the quick turnaround you had in getting the new Elliott (tool) on here. Look forward to working with you in the future.

Just as we guessed… the attention of the Diatool reamer working in the new Index machine… has given us a new opportunity.

Unbelievable!!!! Awesome surface finish and size. The customer should be very happy with the results, as we are. I look forward to continue to use this product line as it has not failed in any application we have used them in. Thanks again.

John D. - Triumph Tool

We had to ream several small diameter holes as well as drilling down to 0.004" diameter. Our failure rate was decreased by 600% when drilling and reaming smaller diameters with the easyZero ER-16 compensation nuts. I used this product in both our CNC lathes and mills with wonderful results.
