New Cutter Diameters to TungForce-Feed – High Feed Mill Line


Iwaki, June 2020 — Tungaloy has expanded its TungForce-Feed line of small-diameter high feed milling cutters by adding new cutter diameters.

TungForce-Feed features a large rake angle and positive inclination angle on the cutting edge that provide excellent chip control while reducing spindle loads and energy consumption. This allows a higher feed rate or greater depth of cut to be applied for improved efficiency and, by working in synergy with the cutter’s high insert density design, produces 130%-150% gain in metal removal rates.

A strong insert corner is built with an added thickness that withstands high cutting force and prevents the cutting edge from fracturing. The toolholder has robust M2 screws that makes handling easier and reduces screw neck shearing that can be a common occurrence during high cutting force applications.

The proven success of the TungForce-Feed line of indexable high feed milling cutters has promoted an expansion to include cutters in 20 mm and 25 mm metric diameters and 0.75″ and 1.00″ imperial.  These new cutter diameters join the existing range from 8 mm to 16 mm.  This addition enhances the cutters’ application range in exotic materials for cutting depths of 0.5 mm or less.

TungForce-Feed boasts a higher insert density when compared with competitors’ cutters of the same size, allowing higher table feeds to be applied for exceptional manufacturing economy. The cutter is particularly effective and beneficial for manufacturers of exotic material components, typical in the aerospace and heavy industries, who are struggling with machining inefficiency with unpredictable tool life. It allows increased feed per tooth with high insert density for improved metal removal rates and long, predictable tool life
