The last quality swing brace left. Has jaw capacity of 3.5 to 16mm, weighs 1100 grams & is 360mm overall. This French model works extremely smoothly due to the ball bearing mounting of its rear pad. The chuck has a right-left adjustable ratchet, which enables drilling and screwing even in confined spaces.

Which to choose? If you intend to use hex shank devices then the 3 jaw option is best. If you have legacy tapered square Jennings bits or reular round shanks to grip then this suggests the 4 jaw version.
