Drill Head Cutting Tool System Offers Expanded Offerings

Tungaloy’s expanded DrillMeister exchangeable head drill system now includes 85 new drill heads in total of DMP, DMC and DMF drill heads in wear-resistant AH9130 grade.

DrillMeister is an exchangeable head drill system said to offer both the efficiency of solid carbide drills and the productivity of indexable drills. The latest developments include the expansion of DMP drill head line. Its diameter range of 6.0 to 9.9 mm (0.236" to 0.390") has been expanded with AH9130 grade, making all standard DMP drill heads in the 6.0- to 25.9-mm diameter range available in 0.1 mm (0.004") increments in wear-resistant AH9130 grade, as well as existing general-purpose AH725.

Featuring a proprietary, self-centering edge geometry, the DMC drill head facilitates quick penetration into materials, enabling high precision and stable drilling without the need for a pilot hole for up to 12xD drilling depths, the company says. This expansion has enhanced the DMC drill head line in the 20.0 to 25.9 mm (0.787" to 1.020") diameter range. In addition, new drill heads have been added for the previously unavailable diameters in this range, making the 5.0 to 25.9 mm (0.197" to 1.020") drill head range available in 0.1 mm (0.004") 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 is said to act as a pilot to provide accurate hole positioning and straightness for hole depths of up to 8xD without the need to drill a pilot hole. This expansion has added 14 new drill heads to the diameters ranging from 10.0 to 19.9 mm (0.394" to 0.783").
