The ETBB07 is an offset (stepped) tungsten bucking bar for rivets in recessed or stepped structure that a straight bar bottoms out against. At 2.85 lb and 6 by 1.5 by 0.75 inches it packs the bucking mass of a much larger steel bar into a compact block, so shop heads form clean with less shock to your hand.
The stepped profile clears a flange, a spar cap, or a raised edge while keeping dense tungsten mass directly behind the rivet. It suits recessed and stepped structure where a straight bar cannot reach the bucktail squarely, and the high density means the bar stays planted under the gun instead of bouncing.

Questions about this bar
What is the ETBB07 tungsten bucking bar used for?
The ETBB07 is a offset tungsten bucking bar for stepped and recessed structure, where the offset steps the working face away from an obstruction to reach the rivet. Hold it flat and square against the rivet tail so the shop head forms evenly.
How much does the ETBB07 bucking bar weigh and what size is it?
The ETBB07 weighs 2.85 lb and measures 6 by 1.5 by 0.75 inches. You buy a bucking bar by weight, and tungsten packs that weight into a far smaller block than steel.
Why is the ETBB07 made of tungsten instead of steel?
Tungsten alloy is about 2.5 times denser than steel, so the ETBB07 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.
