Tungaloy adds a line of positive style inserts to its BX480 insert series, a well-proven T-CBN grade for efficient turning of sintered powder metals and cast iron.
BX480 is a high cBN content T-CBN grade and has a well-sintered cubic boron nitride grain structure with a good balance of wear and fracture resistance, yielding long and stable tool life in abrasive applications, such as heavy interrupted cuts of sintered powder metals. BX480 effectively reduces heat build-up near the cutting edge due to high thermal conductive capabilities, thus providing long and predictable tool life in high speed continuous cuts to interrupted cuts of cast iron.
This expansion adds 20 new positive inserts to the BX480 series ensuring free cutting action in unstable, low rigidity workpieces. Combined with the existing negative insert line, BX480 now provides higher productivity in machining a wider spectrum of powder metals and high speed finishing of cast iron.
BX480 at a Glance:
Provides long and stable tool life in heavy interrupted machining of sintered powder metals
High thermal conductivity ensures tool life stability and predictability in high speed continuous cuts to interrupted cuts of cast iron
Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.
Crystal manufactured from boron nitride under high pressure and temperature. Used to cut hard-to-machine ferrous and nickel-base materials up to 70 HRC. Second hardest material after diamond. See superabrasive tools.

Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.

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. 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 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 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. 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.
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.
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.
