COUPLING SLEEVE
The 552 014 12 SLEEVE, COUPLING is a critical connection point between the drifter's shank adapter and the first drill rod. This sleeve ensures that full rotation torque and impact energy are transferred efficiently to the drill string for optimal penetration rates.

Full Technical Description
552 014 12 SLEEVE, COUPLING This coupling sleeve serves as the primary link for transmitting power from the rock drill to the drill steel. Its internal threads engage with both the shank adapter and the drill rod, creating a solid connection that must withstand intense rotational forces and percussive shockwaves. A secure fit here is essential for straight holes and effective energy transfer.
Wear on this component directly impacts drilling performance. When the internal threads wear out, the connection becomes loose, causing a significant loss of impact energy before it even reaches the rock. This not only slows down drilling but also accelerates wear on the expensive shank adapter and rod threads, leading to premature failures and increased operational costs.
Regularly inspect the sleeve's internal threads for rounding or cracking. If you notice excessive wobble at the connection point or find it difficult to thread onto the rod, it's time for a replacement. Using proper thread grease and avoiding over-tightening will help extend its service life.
