Tungaloy continuously expands the advantages of its AddMeisterDrill exchangeable-head drill solution into a smaller diameter range. Ten new DMC precision drill heads have been added to the line for diameters ranging from 4.0 mm (.157″) to 4.9 mm (.192″), expanding the entire range from 4.0 mm (.157″) up to 5.9 mm (.232″).
AddMeisterDrill exchangeable-head drills feature superior cutting performance of solid carbide drills and the ease-of-use of the DrillMeister modular drill concept, while allowing quick and secure exchanges of extremely small drill heads in diameters ranging from 4.0 mm (.157″) to 5.9 mm (.232″) thanks to its dedicated key. In addition, unique coolant outlets furnished on the drill body provides an increased ratio of through-coolant supply for improved chip evacuation and process security.
Featuring a unique self-centering chisel tip geometry, DMC drill heads facilitate quick penetration into materials, allowing high precision and stable drilling. The new drill heads are available in AH9130 PVD-coated grade developed specifically for drilling applications. Extremely wear resistant, the grade provides long tool life in carbon steel and alloy steel applications.
“Following the previously introduced 5.0-5.9 mm (.197″-.232″) diameter range, the new DMC drill heads are developed specifically for opening bores in diameters smaller than 5.0 mm.” Explains Yuki Oikawa, the product manager of AddMeisterDrill about the features of the new drill heads. “The cutting edge geometry and edge preparation are optimized to achieve superior cutting edge integrity and self-centering capability. Also, the drill heads are ground to precision and coated with a thin, uniform coating film thickness for stable hole quality and long tool life.”
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
Conditioning of the cutting edge, such as a honing or chamfering, to make it stronger and less susceptible to chipping. A chamfer is a bevel on the tool’s cutting edge; the angle is measured from the cutting face downward and generally varies from 25° to 45°. Honing is the process of rounding or blunting the cutting edge with abrasives, either manually or mechanically.

DrillMeister features simple and swift drill head indexing due to its self-clamping system. Tool replacement is easy: just replace the drill head. There is no need to remove the entire drill body from the toolholder and re-adjust the tool overhang, thus reducing a large amount of tool change time.
Tungaloy Corp. further expands its indexable-insert 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.
Tungaloy Corp. has expanded the TungTurn-Jet line, the turning tool system with high-pressure coolant capability. Until now, coolant was simply applied by flooding the cutting area, which can cause chips generated during machining to interfere with the coolant flow, preventing it from reaching the…
Tungaloy Corp. added threading inserts with sharp cutting edges to its TetraMini-Cut insert series, which allows undercutting and finishing of a flange wall. Complemented by the new PVD grade, SH725, TetraMini-Cut’s new threading insert features sharp cutting edges, making it suitable for cutting…
Tungaloy America Inc. offers the DuoJustCut parting tool for Swiss-style lathes. The clamping system rigidly clamps inserts, and the optimized overhang length delivers stable and productive machining, according to the company.
DoTwistBall from Tungaloy America is an ideal tool for die and mold, as well as general engineering. Combined with a rigid clamping mechanism, the insert’s unique twisted shape improves chip evacuation for stable machining and long tool life in roughing operations.
