With a tenon-gripping range of 1-1/2" for its #2 jaws—best in our test of 10 midsize chucks—this chuck holds even large turning blanks securely. The screw center installs with a double-locking system that ensures it won’t come loose. We wish its rack-and-pinion mechanism turned smoother than it does.
