For deep-hole drilling applications up to 30XD, the new solid-carbide WIDIA-Rubig deep-hole drills remove between three and four times the metal compared to gun drills, in addition to delivering excellent hole quality and cycle times.

“Three- or four-fold increases in metal-removal rates mean significant improvements in a customer’s bottom line, whether it be in increased throughput, additional capacity for drilling equipment, or better-utilized personnel,” according to Chris Merlin, senior global product manager, holemaking.

The WIDIA portfolio covers a wide range of precision-engineered products and custom services. It includes thousands of milling, turning, holemaking, and tooling systems products available through authorized distributors.

The new Widia-Rubig deep-hole drills are available with length ratios in 15XD, 20XD, 25XD, and 30XD. Available diameters range from 3.0 to 13.0 mm.

Along with improved performance, the tool supplier explains that its new solid-carbide deep-hole drills increase process versatility because they require no special drivers or guide bushings. Also, whereas gun drilling machines are dedicated to gun drilling exclusively, Widia-Rubig deep-hole drills may be used in machining centers, which eliminates the need for specialized capital equipment.

Widia-Rubig further maintains that the new drills’ 132 ° cone-point geometry give it low thrust and excellent centering ability, for increased hole quality. Its four-margin design improves stability in the cut and an advanced PVD coating and highly polished surfaces increase wear resistance and reduce friction on margins and cutting edges.

“Higher tool life and feed rates are considerable advantages with these tools, and adding that customers will be drilling more holes per drill and getting longer life and more regrinds per drill seals the deal,” stated Merlin.
