What to do if the diamond core bit doesn’t rotate on my Hilti Tools?
If the diamond core bit is not rotating, it may have become jammed in the base material. To resolve this, guide the diamond core drilling machine in a straight line. Then, disconnect the mains plug from the power outlet and use an open-end wrench to grip the diamond core bit close to the connection end. Rotate the wrench to release the bit.
What to do if the service indicator shows nothing on my Hilti Tools?
If the service indicator isn't showing anything, first ensure that the PRCD is functioning and switched on. Then check for any interruptions in the electric supply by testing another electric tool or appliance in the same outlet. Also, inspect the plug connections, supply cord, power supply line, and main supply fuse. If there is water in the motor, allow the diamond core drilling machine to dry out completely in a warm, dry place.
Why is the drilling speed decreasing on my Hilti Tools?
Several factors can cause a decrease in drilling speed. It could be due to reaching the maximum drilling depth, in which case you should remove the core and use a longer core bit. Alternatively, the core might be stuck in the diamond core bit, requiring you to remove it. Other potential causes include using the wrong core bit specification for the base material (select a more suitable one), high steel content (select a more suitable diamond core bit specification), a defective diamond core bit (check for damage and replace if necessary), a polished diamond core bit (sharpen it by drilling into a sharpening plate), or an incorrect water flow rate (adjust the water flow regulator). Finally, ensure the connection end is clean and the diamond core bit is correctly fitted.
What to do if the diamond core bit can’t be fitted into the chuck of my Hilti DD 30-W Drill?
If the diamond core bit can’t be fitted into the chuck of your Hilti Drill, the core bit connection end or chuck might be dirty or damaged. Clean the connection end and/or the chuck, or replace these parts if necessary. Also, make sure the chuck operating lever is fully open.
Why does the diamond core bit have too much play in my Hilti Drill?
If the diamond core bit has too much play in your Hilti Drill, the connection end might be defective. Check it and replace it if necessary. Also, ensure that the chuck lever is closed.
What to do if the diamond core bit doesn’t rotate on my Hilti DD 30-W Drill?
If the diamond core bit doesn’t rotate on your Hilti Drill, it may be jammed in the base material. Ensure you guide the drilling machine in a straight line.

What does it mean when the service indicator lights up on my Hilti Drill?
If the service indicator lights up on your Hilti Drill, it could mean that the carbon brush wear limit has almost been reached. In this case, have the carbon brushes replaced at the next opportunity. It can also mean that the carbon brushes have been changed and must be run in. Run in the carbon brushes by letting the machine run under no load for at least 1 minute without interruption.
