CHEVRON-STYLE MILLING CUTTER SIGNIFICANTLY INCREASES TITANIUM METAL REMOVAL RATES
Ideal for aerospace part design applications that often call for up to 80 percent metal removal rates, the 5230VS12 long edge cutter from ATI Stellram achieves metal removal rates up to two times greater than comparable cutters on the market.

The Stellram 5230VS12, an ATI Stellram (LaVergne, TN) chevron-style milling cutter, is designed specifically for machining titanium and other difficult to machine materials, such as nickel-based alloys and cobalt-based alloys.
In comparison studies, the Stellram 5230VS12 cutter achieved metal removal rates up to two times greater than comparable cutters on the market. This is vital in aerospace applications where part design often calls for up to 80 percent metal removal.
The 5230VS12 chevron cutter positions multiple inserts along the cutting edge of each helical flute. This advanced design of the insert placement provides smooth, progressive penetration and cutting action for extended tool life, lower power consumption and up to a 30 percent improvement in surface finish.
Cutters range from 2.5 in to 4.0 in diameter with four to six flutes. Depending on flute length, from 6 to 14 inserts can be positioned along each flute. Individual coolant jets to each insert provide constant chip evacuation and temperature stability in the cutting zone. Two insert grades are available for the Stellram 5230VS12:
Grade X500 is a member of ATI Stellram’s high performance premium X-Grade technology family of carbide inserts designed for the toughest applications in nickel-based alloys, cobalt-based alloys, titanium and titanium-based alloys.
Grade SP6519 offers the combination of a tough substrate with the latest generation of TiAlN super nano coating. This versatile grade is equally suited for both high-temperature alloys and stainless steels.
