Cutting tool and tooling systems manufacturer Sandvik Coromant (Fair Lawn, N.J.) has debuted its Online Drilling Knowledge Hub at www.drillingknowledge.com, a website dedicated to optimizing drilling process and customizing results to the needs of the user. Sandvik notes that holemaking holds the potential to make — or break — an operators’ productivity and profitability. Resources on the site include a cost-per-hole calculator and a drilling product selector meant to match appropriate drills to any application. Users can browse through in-person events and training opportunities, held in Application and Productivity Centers nationwide. And a full drilling resource library acts as a compendium of articles, case studies, webcasts and videos depicting common drilling obstacles and solutions.
