The 30 is the most widely used handpiece in the jewelry world, featuring a three-jaw chuck that can hold any shank size up to 4mm. This versatility makes it the “go-to” tool for a vast array of tasks, from drilling large holes with standard drill bits to using specialized polishing wheels and burs. The handpiece is built with high-quality ball bearings for smooth, quiet operation and is designed for a comfortable, ergonomic grip. It includes a chuck key for secure tool tightening, ensuring that even under high torque, your burs and drills remain perfectly centered and secure.
