Manual Tang Break Tools

These are used for breaking-off the tang in a Screw Thread Insert after installation of the same in a tapped hole.This is easily accomplished by placing the punch of the Tang Break-off Tool into the installed insert and resting tool squarely on the insert tang. Striking the top of the tool with a hammer, using a sharp blow breaks off the tang.

Semi-Automatic Tang Break Tools

This Tool has a spring loaded sleeve which actuates the punch causing it to strike a uniform blow against the tang in the assembled insert. The operation of this tool is single handed (as against manual tang break-off tool requiring both hands) and excludes the use of a hammer.These are suitable for inserts ranging from M2 to M10 or equivalent inch sizes.
