Norton RazorStar™ Abrasives Offer Unprecedented Grinding Performance

Breakthrough Engineered Shaped Ceramic Grain Technology Consistently Cuts Sharp 

WORCESTER, MA, U.S.A. (January 15, 2024) – Saint-Gobain Abrasives, one of the world’s largest abrasives manufacturers, has announced the introduction of Norton RazorStar™ Fiber Discs, Quick-Change Discs and Belts featuring innovative engineered shaped ceramic grain, a breakthrough technology with unbeatable performance even in the toughest grinding applications. A unique combination of razor-sharp grains with a supersized grinding aid helps to significantly reduce heat generation for cooler cuts and longer life on a range of materials such as carbon steel, aluminum, stainless steel, nickel alloys and other hard-to-grind metals. 

Enabling exceptionally high cut rates and material removal, the engineered shaped grain in Norton RazorStar™ belts and discs features a consistent shape from grain-to-grain along with razor-sharp cutting points. For long, unparalleled abrasives life, the unique patented geometry and tough micro-structure enable the grain to stay sharp, as new cutting points are exposed when the grain fractures. RazorStar™ abrasive products also features a very high concentration of grains that are oriented in an upright position, so the abrasives are ready to cut and aggressively perform at their sharpest point.

“RazorStar™ fiber discs have raised the bar and are setting the standard in grinding productivity and quality,” said Mr. Jeremy Spencer, Product Manager, Norton | Saint-Gobain Abrasives. “We are seeing an up to 50% cutting performance improvement compared with other ceramic discs on the market today, and we are very excited to offer our customers new abrasive discs that will take their grinding performance to a new level of efficiency when removing welds, grinding, beveling and doing heavy deburring.”

Mr. John Benkoczy, Sr. Product Manager, Norton | Saint-Gobain Abrasives added, “RazorStar™ Belts, which are designed for medium to high pressure metal removal in challenging robotic or off-hand applications, are producing the same number of parts with fewer belts and less machining and changeover time, while consuming less energy.” 

The new RazorStar™ Fiber Discs, Quick-Change Discs and Belts are offered in 36-grit: 

  • RazorStar™ Fiber Discs are available in sizes ranging from 4 1/2” to 9” in 7/8 hole, speed-change and AVOS discs. Key markets include MRO, metal fabrication, welding, oil and gas, energy and ship building. 
  • RazorStar™ Quick-Change Discs, which are available in two and three inch sizes, feature a strong backing that stands up to extreme pressure when removing stock, deburring, beveling and blending, and are especially well suited for aerospace, MRO, metal fabrication, welding and energy industry applications. 
  • RazorStar™ Belts are made-to-order and are ideal for impact grinding, robotic or off-hand applications in markets such as foundry, aerospace, automotive, metal fabrication, oil and gas and general engineering.
