JAW R.H.

236 176 17 JAW R.H is what actually grabs onto the shank adapter in your rock drill. It’s the business end that takes all the rotational torque and impact energy from the piston and transmits it right into the drill string. When everything's working right, these jaws keep that shank adapter locked in tight, making sure you get maximum energy transfer downhole without any slop or wasted motion. It's a critical piece for getting proper penetration rates and keeping everything aligned.

When these jaws start getting worn out, you’ll definitely notice it. Usually what happens is the grip on the shank adapter loosens up, and you'll start hearing a distinct clunking or feeling excessive vibration through the drill string, especially when you're really leaning on it. That lost energy means slower drilling, and it puts extra stress on the rest of the rock drill components, like the chuck adapter and even the piston itself. Don't ignore those noises; they're telling you something's not right.

Replacing these jaws isn't too complicated, but you gotta make sure you do it right. Always replace the whole kit, not just one jaw, because they wear as a set. And here’s a common one: don't forget to thoroughly inspect the chuck adapter and the front guide bushing while you're in there. Those parts often take a beating right alongside the jaws, and putting new jaws into a worn chuck adapter is just asking for trouble down the road.
