New Indexable Milling Grade

Sandvik Coromant released GC1240, a new indexable milling grade, on March 23. According to a company statement, the grade’s Zertivo proprietary coating, made from a combination of titanium aluminum nitride and titanium silicium nitride and applied with physical vapor deposition, allows GC1240 to resist thermal cracking and abrasive wear. The grade is suitable for use in machining stainless steel, and Sandvik Coromant says the tool’s stable edge line ensures secure machining in wet and dry conditions.

In a company statement, Sandvik Coromant’s global product application manager Wayne Mayson said GC1240 is especially suitable for dry machining and austenitic materials. In dry conditions the GC1240 can machine at higher cutting speeds, Mayson said, enabling lower energy consumption and reduced coolant usage.

“GC1240 unlocks higher productivity, lower cost per part and new sustainability opportunities through impressive and tangible results,” Mayson said.

According to Sandvik, grade GC1240 is recommended for light roughing to finishing in stainless steel for strong, positive, and sharp geometries, as well as heat-resistant super alloys and titanium at certain speeds. For more information, see Sandvik Coromant’s website.
