Sandvik Coromant CoroDrill® 860 Solid Carbide Drill
The CoroDrill® 860 is engineered for supreme drilling efficiency, maximum metal removal rates, and superior hole quality. Developed with advanced grade technologies and refined cutting geometries, the CoroDrill® 860 reduces machining cycle times significantly while extending tool life in high-demand automated manufacturing environments.
Featuring a rigid solid carbide structure paired with specialized web designs and corner radii, the CoroDrill® 860 provides excellent chip formation, rapid chip clearance, and tight hole tolerances. Internal precision coolant channels direct high-pressure coolant straight to the cutting edge, reducing heat buildup and preventing edge wear during deep drilling operations.
Key Features & Benefits
