Walter Surface Technologies, Windsor, Conn., recently launched the Walter Abrasives Selector app designed to help metalworking professionals select the optimum abrasive solution for any possible application they may encounter, according to a company news release issued Feb. 9.

Available for all iOS and Android smartphones, the free app offers a simple user interface that reportedly makes it easy to select an operation—finishing, sanding, cutting, grinding or blending—specify a tool of choice, then select the desired finish, the company explained. The app also provides easy access to technical reference data, including safety data sheets, training videos and Walter product information.

Customers who download and install the new app between Feb. 9 and March 11 will be entered in a contest to win one of three $150 prepaid Visa gift cards. The drawing takes place March 14.

The Walter Abrasives Selector app is available through the Apple App Store (iOS 7.1 or later) and Google Play (Android 4.2 or later).
