Tungaloy Corp. is continuously expanding its TungMeister changeable-head endmill system. The latest addition involves a new line of modular heads for the TungForce-Rec indexable miniature shoulder milling cutter series.
TungForce-Rec features an innovative V-shaped insert, designed to avoid insert movement under high centrifugal force, while delivering excellent machining reliability even when used at a high metal removal rate. The insert’s remarkably large rake angle ensures light cutting action, while the obtuse angled flank face of the insert strengthens the cutting edge and avoids chipping. The cutter body design allows for far more compact and sturdy pockets than other cutters with flat bottom inserts. Therefore, a larger core diameter is retained in the given small tool diameter, making TungForce-Rec a perfect miniature shoulder mill with incomparable rigidity for shouldering, slotting, 3D profiling and various other applications.
TungForce-Rec inserts feature a maximum 6 mm (0.24”) depth of cut and are available in three different grades for a wide range of materials. Tool diameters are available from ø8 mm (0.32”) to ø16 mm (0.63”).
Characterized by a rigid body structure and unique insert design, TungForce-Rec ensures reliable, high precision miniature shoulder milling in a wide range of materials, according to the company. Now the TungMeister changeable-head system has a lineup of TungForce-Rec modules. The indexable endmill system features secure coupling with minimal bending at the flange and tapered shank contacts. An optimal tool shank selection is possible from the standard shank material lineup of cemented carbide, steel and vibration-damping pure tungsten.

- depth of cut
depth of cut
Distance between the bottom of the cut and the uncut surface of the workpiece, measured in a direction at right angles to the machined surface of the workpiece.
Milling cutter held by its shank that cuts on its periphery and, if so configured, on its free end. Takes a variety of shapes (single- and double-end, roughing, ballnose and cup-end) and sizes (stub, medium, long and extra-long). Also comes with differing numbers of flutes.
- flat ( screw flat)
flat ( screw flat)
Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- milling cutter
Loosely, any milling tool. Horizontal cutters take the form of plain milling cutters, plain spiral-tooth cutters, helical cutters, side-milling cutters, staggered-tooth side-milling cutters, facemilling cutters, angular cutters, double-angle cutters, convex and concave form-milling cutters, straddle-sprocket cutters, spur-gear cutters, corner-rounding cutters and slitting saws. Vertical cutters use shank-mounted cutting tools, including endmills, T-slot cutters, Woodruff keyseat cutters and dovetail cutters; these may also be used on horizontal mills. See milling.
- milling machine ( mill)
milling machine ( mill)
Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.
Machining vertical edges of workpieces having irregular contours; normally performed with an endmill in a vertical spindle on a milling machine or with a profiler, following a pattern. See mill, milling machine.
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
Machining, normally milling, that creates slots, grooves and similar recesses in workpieces, including T-slots and dovetails.
