Walter Tools is adding more than 3,000 new solid carbide milling tools in inch sizes. This expansion includes shoulder/slot mills for cutting super alloys and other high-temperature alloys, titanium, and stainless steel (ISO S and M material groups) at the highest level.

The MA377/MA373 Supreme milling cutters (4,5, and 6 flutes) for machining titanium and stainless steels are available in sizes from 1/8 to 1¼ in. diameter. The tools are available with or without corner radii, and with or without chip splitters. These mills are suitable for slotting, peripheral milling, trochoidal milling, and high-efficiency milling. The offered chipbreaker reduces chip nesting issues and deflection stemming from excess tool pressure.

The MD177/MD173 Supreme milling cutters (7 flutes) have more teeth to boost productivity when machining titanium and high-temperature alloys. The tools are available in sizes from ¼ to 1 in. diameter. The uneven pitch on the tools reduces vibration and allows the entire length of the cutting edge to be used to provide uniform wear. The cutting tools supply outstanding productivity and process reliability.

The MD177 cutter creates smooth surfaces without “waterlines.” The MD173 is equipped with chipbreakers that provide process reliability with high metal removal rates.

The MA375 Supreme cutter (4,5 and 7 flutes) is for roughing and finishing Inconel and other nickel-base super alloys. The tool is available in sizes from 1/8 to 1 in. diameter and features a variable helix and variable indexing. The 4 and 5 flute versions are for aggressive slotting up to ½ in. diameter, peripheral milling, and trochoidal machining. The 7-flute mill is designed for dynamic machining and excels at high workpiece hardness levels.
