The ETBB09 is a long reach tungsten bucking bar for backing rivets deep inside wings, spars, and box structure. At 1.7 lb and 10 x 2 x 1 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 slim one inch shank carries the bar far past an open edge, a knurled face grips the work, and an angled foot seats tungsten mass on the rivet tail. At 1.7 lb it brings heavy backing to large rivets and stays planted under the gun.

Questions about this bar
What is the ETBB09 tungsten bucking bar used for?
The ETBB09 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 ETBB09 bucking bar weigh and what size is it?
The ETBB09 weighs 1.7 lb and measures 10 by 2 by 1 inches. You buy a bucking bar by weight, and tungsten packs that weight into a far smaller block than steel.
Why is the ETBB09 made of tungsten instead of steel?
Tungsten alloy is about 2.5 times denser than steel, so the ETBB09 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.
