easyZERO runout compensation nuts available in convenient kit form

Monaghan Tooling Group now offers Diatool easyZERO runout compensation nuts in convenient kit form.


easyZERO kitsDesigned for round tools using ER collets (ER16 to ER40), the easyZERO quickly and easily corrects runout errors and misalignment for round tools, providing reamers with the stability to hold tolerances as tight as 0.0011 inch. A variety of kits are stocked for immediate shipment – ranging from a basic kit (easyZERO nut with hex key) to a comprehensive kit that includes the nut, hex key, spanner, and ER collet.

With this unique technology, cutting edges equally share the chip load, ensuring concentric cutting, consistent tool wear, and extended tool life. By rapidly dialing in runout, users spend less time resetting tools and collets, improving efficiency, reducing scrap rates, and lowering overall costs.

Simple Installation

Installing the easyZERO is as straightforward as it is effective – simply replace the existing ER collet chuck nut with the easyZERO runout compensation nut. With six adjustment screws, the nut allows users to dial out up to 0.0011 inch of runout in seconds. A video demonstration can be seen at https://www.youtube.com/watch?v=DcpxMP9zVRQ&t=26s
