Allied’s new 4TEX drill is suited for making shallow 2xD, 3xD and 4xD holes in the 12 mm – 47 mm (.472″ – 1.850″) range. “The 4TEX drill’s single effective cutting edge provides higher penetration rates than standard twist drills on light duty machines,” said a company spokesperson. The center coolant outlet was eliminated to increase the drill’s core strength in this design, resulting in improved hole size and straightness. Alternatively, twisted coolant outlets were added to improve hole straightness and penetration rates by enhancing coolant flow and chip evacuation. Insert geometries for standard ISO material categories improve hole quality and penetration rate, while eliminating issues from chips wrapping the tool. 4TEX inserts are four-sided. The drills will be stocked in both imperial and metric shanks with standard fractional diameters, as well as every .5 mm diameter up to 26 mm and every 1 mm up to 47 mm.
