Tungaloy Corp. has expanded its DrillMeister series of interchangeable-tip drills to include diameters of 6.0 to 9.9 mm (available with TID-type drill bodies of 1.5D, 3D, 5D and 8D) for small-diameter hole making in a variety of materials.  The flange-type bodies feature high helical flute angles and special polished flute surfaces for increased chip evacuation. According to the company, excellent chip evacuation can be achieved even in drilling holes of 5×D or deeper, where chip evacuation tends to be difficult.

A self-clamping system simplifies drill-head indexing. Drill heads can be replaced without the need to remove the whole drill body from the toolholder and readjust the tool overhang, reducing tool-change time.
