Fine processing Precision machining on both internal bores and external surfaces ensures accurate fit and smooth operation. Large cutting diameter Designed for torque applications with a large cutting diameter, enabling efficient drilling and milling tasks that require substantial tool engagement. Cooperate use Compatibility with tapered shank drill, tapered shank milling cutter, and tapered reamer allows flexible tool pairing in a single setup. Function Taper shank drill chuck is provided to improve work efficiency through quick and secure tool changes. The drill sleeve enables changing the taper of the connecting shaft to match different equipment or spindles. Use scenarios In metalworking, use for drilling largediameter holes where torque and stable guidance are needed to maintain accuracy and surface finish. In a multitool workshop, leverage the compatibility with tapered shank drills, milling cutters, and reamers to minimize tool changes and downtime during drilling, milling, and reaming sequences. On a production line, employ the drill sleeve to adapt the taper to different spindle configurations, enabling quick crossmachine use without additional adapters.
