Iwaki, June 2022—Tungaloy is continuously expanding on its successful DrillMeister exchangeable head drill system. The latest developments include the expansion of the DMP general-purpose drill head line with AH9130 grade drill heads for diameters ranging from 10.0 millimeters (.394 inches) to 25.9 millimeters (1.020 inches). The DMF counterboring drill head line now offers additional AH9130 grade drill heads, making diameters ranging from 6.0 millimeters (.236 inches) to 9.9 millimeters (.390 inches) to be available in 0.1 millimeter (.004 inch) increments.
DrillMeister is an innovative exchangeable head drill system that has both the efficiency of solid carbide drills and the productivity of indexable drills and also simplifies drilling and chamfering processes. The exchangeable drill heads are available in two grades: AH725 is a general-purpose PVD grade that ensures process reliability across various materials. AH9130 is a latest PVD grade developed specifically for hole making applications that provides the drill with superior wear resistance.
Designed for general purpose drilling applications, DMP drill head line is currently available in AH725 for all drill head diameters offered; while AH9130 is only available for specific diameters, not having been able to address the drilling needs for all hole diameters. In this expansion, the DMP line has been expanded with additional AH9130 drill head offerings, complementing the existing DMP drill heads in the 10.0 millimeters to 25.9 millimeters (from .394 inches to 1.020 inches) diameter range, while providing the range with increased grade options in 0.1 millimeter (.004 inch) increments.
DMF counterboring drill head line has also been expanded with additional diameters. DMF features a 180 degree flat cutting edge and conical center point, which acts as a pilot to provide accurate hole positioning and straightness for hole depths of up to 8xD without the need for a pilot hole. This expansion makes DMF drill head line available in 0.1 millimeter (.004 inch) increments for diameters ranging from 6.0 to 9.9 millimeters (from .236 inches to .390 inches).
