Tungaloy is expanding TungForce-Feed, a line of indexable small-diameter high feed milling cutters, to include R2 inserts featuring corner radii of 2.0 mm (.079″).

Offered in cutter diameters ranging from ø8 mm to ø16 mm (ø.315″ – ø.625″), TungForce-Feed ensures high productivity and economy in profiling die and mold parts over conventional solid end mills and indexable tools of similar size.

When designing a CAM program for high feed inserts to machine complex 3D profiles typical in mold making, it is common to use a theoretical corner radius for programming the insert radius. This method leaves excessive stock on the workpiece after machining, adding processes. To create a good platform for subsequent, often final, finishing process, many job shops are using solid carbide square end mills with large radii in the roughing process.

The new R2 inserts require no programming need for the theoretical corner radius. Its 2.0 mm corner radius leaves no uncut material on the machined surface. TungForce-Feed makes a good replacement for costly solid carbide end mills, helping customers reduce tool costs.

At a Glance

• Fine tolerance finishing with no uncut material
• Good replacement for solid carbide end mills to lower tool costs
