DeepTriDrill –Tungaloy expands its small diameter range in the indexable gundrill series

Tungaloy Corporation further expands the industry’s leading inserted indexable gundrill line, DeepTriDrill, with options down to a diameter range of 14-15.9 mm.

Deep hole drilling is a challenging operation and often creates a bottleneck in holemaking shops around the globe. The brazed gundrill or solid twist drill are staple tools in such operations. A typical brazed gundrill has a single point, uncoated carbide tip. Due to these properties, high parameter drilling has not been possible. A solid twist drill is better for high feed drilling; however, curved holes and chip clogging are common setbacks with this type of tool. These traditional deep hole drills are expensive and require reconditioning and inventory management, which incurs significant extra cost for every deep drilling shop.

DeepTriDrill features one insert and two guide pads oriented in an optimized position on the drill head. This achieves tight tolerances with circularity and straightness as well as an excellent surface finish, which a brazed gundrill could traditionally attain. The insert incorporates chipsplitters on the chipbreaker geometry, which break chips into smaller pieces to facilitate chip evacuation and reduce cutting force, enabling a higher feed rate than traditional gundrills. The coated insert and guide pads also allows DeepTriDrill to reach higher cutting speeds, which has been difficult with brazed gundrills.

DeepTriDrill not only increases machining performance but also facilitates inventory management thanks to its indexable system. This small diameter range expansion complements DeepTriDrill, further enhancing its product positioning in the deep hole drilling market for high productivity and economy.
