Engineered from a single steel billet, this dynamically balanced mini chuck ensures vibration-free rotation even at speeds up to 35,000 rpm. The precision-machined integral collet design allows for easy bit changes and perfect centering of micro drill bits to prevent tool wear.

• Precision capacity of 0 in. to 0.039 in. (0.35 mm - 0.99 mm), ideal for micro drill bits #60 through #80.
• Features a 1/8 in. straight shank compatible with flexible shafts, rotary tools, hand grinders, and most motorized drills.
• Keyless design allows for rapid and easy bit swaps to streamline precision drilling tasks.
• Dynamically balanced and machined from a single steel billet for optimum concentricity and vibration-free operation up to 35,000 rpm.
• New and improved manufacturing ensures a centered collet cut for maximum accuracy and reduced tool wear.
