Tungsten Bucking Bar, 1.07 lb

A distributor's tungsten bars run from 1.07 lb to 2.87 lb; this is the lightest. The listing does not give the bar's dimensions, so check them with a distributor's before ordering for a tight space.

The bar forms the shop head, and the rivet length calculator gives the head you should be forming. The listing also cites a university study on vibration; it does not name it, so we do not repeat the claim.
