? Surface Grinding Segment,Segmented Wheels ? Harness the grinding power of specially blended aluminum oxide abrasive on the Gemini 53A AO surface grinding segment to handle versatile surface grinding jobs. Thanks to a porous vitrified bond, this segment allows for cool cuts on your heat-sensitive applications with increased chip clearance, maximized coolant flow and reduced loading for quality results. You get good performance at an economical value for your grinding surface machines with Hanchett, Mattison, Norton, Cortland and Cortland Bonus Grind chucks. This grinding segment works on a variety of materials, especially soft carbon steels and tool steels, to tackle a range of jobs. ? Specially blended aluminum oxide abrasive for many surface grinding applications ? The porous vitrified bond increases chip clearance and maximizes coolant flow, reduces loading, and is cool cutting in heat-sensitive applications ? For use in Hanchett, Mattison, and Norton, and Cortland and Cortland Bonus Grind chucks on surface grinding machines ? Good performance and economical value when a broad variety of parts are ground on one machine, particularly soft carbon steels and tool steels ? Consistent performance at an economical initial price
