The ETBB24 is a reach tungsten bucking bar for backing rivets inside tubes, sockets, and deep recesses a block bar cannot enter. At 4.05 lb and 8.625 x 2.5 x 1.5 inches, it brings the backing mass of a much larger steel bar to the rivet, so shop heads form clean with less shock to your hand.
A round post carries tungsten mass down to the rivet tail while the flat base gives a stable hand grip. At roughly 2.5 times the density of steel it backs the rivet without bouncing.

Questions about this bar
What is the ETBB24 tungsten bucking bar used for?
The ETBB24 is a heavy tungsten bucking bar for larger rivets and thick structure, delivering maximum backing mass in a hand-held bar. Hold it flat and square against the rivet tail so the shop head forms evenly.
How much does the ETBB24 bucking bar weigh and what size is it?
The ETBB24 weighs 4.05 lb and measures 8.625 by 2.5 by 1.5 inches. You buy a bucking bar by weight, and tungsten packs that weight into a far smaller block than steel.
Why is the ETBB24 made of tungsten instead of steel?
Tungsten alloy is about 2.5 times denser than steel, so the ETBB24 delivers the same bucking mass as a steel bar more than twice its size. The compact mass means better access in tight structure and less shock to your hand.
