Tungaloy has added AH9130 insert grade to its DrillForce-Meister line of exchangeable-head drills designed for hole diameters ranging from 20.0 mm to 41.0 mm (.787″ to 1.614″).
AH9130, consisting of a PVD coating layer optimized for drilling applications with a dedicated carbide substrate, is the latest insert grade specifically developed to provide significant tool life improvements and more predictable wear patterns in hole making applications of ISO P (steel), ISO M (stainless steel), and ISO K (cast iron). 17 SMP-style inserts have been released in the latest grade, covering diameters from 20.0 mm to 35.0 mm (.787″ to 1.378″). In addition to Tungaloy’s versatile grade AH725 which covers most ISO materials, AH9130 provides DrillForce-Meister with added process security and tool life improvements in ISO P, M, and K applications.
DrillForce-Meister incorporates a unique exchangeable drill head designed to efficiently open large diameter holes ranging from 20.0 mm to 41.0 mm (.787″ to 1.614″) at a lower cost. The unique drill head features an asymmetric V bottom which is fully supported in a matching pocket of the drill body, providing accurate edge position repeatability and secure insert retention. Additionally, large contact surfaces of the drill head and pocket provides strong support helping the drill head to withstand heavy cutting loads in aggressive drilling operations. The drill body also features welldesigned flutes providing smooth chip control and evacuation in various materials.
DrillForce-Meister eliminates the need for regrinding and recoating, reducing the amount of tool float inventory kept to avoid machine downtime, thus minimizing the overall cost per hole in high volume production lines. A simple exchange of a new drill head guarantees the drill's dimensional stability and tool life predictability meeting the required finished dimensions of the workpiece.
Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.

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. 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 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 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.
Tungaloy Corp. introduces TungTri-Shred, a new shoulder milling cutter for highly productive machining. With today’s dramatic growth in the performance of machine tools, high-speed machining is often the first choice for manufacturers.
DoMini-Mill is a copy mill developed for semifinishing operations, featuring Tungaloy’s latest H-class insert. The economical six-cornered insert with dovetail clamp technology has a double-sided geometry, yet positive flanks, providing sharpness and high cutting edge strength simultaneously.
Tungaloy Corp. offers MillQuadFeed, a new high-feed milling cutter. With a depth of cut up to 0.098” (2.5mm) and a feed rate up to 0.078” (2.0mm) per tooth, MillQuadFeed accomplishes astounding metal-removal rates in rough milling operation, according to the company.
DoTriple-Mill is Tungaloy’s latest facemilling cutter, featuring an innovative dovetail clamping system that will reportedly dramatically reduce insert lift up and excessive shear force imposed on the screws during heavy-duty milling. Compared with the last generation of facemilling platforms,…
Tungaloy Corp. offers TungForce-Rec, the indexable miniature shoulder milling cutter. The TungForce-Rec insert has a unique V-shaped bottom to enhance the insert’s resistance to centrifugal force, assuring reliability and high productivity during high-speed machining, according to the company.
