How to improve the drilling rate of my Hilti DD 150-U Drill?
- Z
  zhangmatthewSep 14, 2025
  A decreasing drilling rate with your Hilti Drill can stem from multiple factors. Here are some things to check: 1. If the maximum drilling depth has been reached, remove the core and use a core bit extension. 2. If the core is stuck in the core bit, remove it. 3. Ensure you're using the correct core bit specification for the base material and that the diamond core bit is not defective (check for damage and replace if necessary). 4. Also, verify that you've selected the right gear and are applying sufficient contact pressure. If the machine has too little power, select the next lower gear. If the diamond core bit is polished, sharpen it by drilling into a sharpening plate.

  If you're having trouble fitting the diamond core bit into the chuck of your Hilti Drill, the issue might be that the core bit connection end or chuck is dirty or damaged. Try cleaning and greasing these parts. If that doesn't work, you may need to replace them.

What to do if the Hilti DD 150-U multifunction display is not showing anything?
- E
  Elizabeth ClarkAug 26, 2025
  If the multifunction display is not showing anything, there could be several reasons. First, check that the PRCD is functioning and switched on. Second, verify that there isn't an interruption in the electric supply by testing another electric tool or appliance, and inspect the plug connections, supply cord, power supply line, and main supply fuse. Finally, if there's water in the motor, allow the drill to dry out completely in a warm, dry place.

Why does my Hilti Drill show a restart interlock?
- J
  Joseph MacdonaldAug 27, 2025
  A restart interlock can occur for several reasons. The motor may have overheated, in which case you should switch the drill off and then on again. A supply network fault or power interruption could also be the cause; check other power consumers and the extension cord length, then switch the drill off and on again. Water in the motor or exceeding the maximum running time with hole-starting mode activated can also trigger this, so dry the drill or switch it off and on again, respectively. Overloading the drill can also cause this issue; avoid repeated disengagement of the slip clutch.

How to fix overheating on my Hilti DD 150-U Drill?

  vmoralesAug 27, 2025
  If your Hilti Drill is overheating, it means the motor has overheated and the drill is running in cooling mode. Wait a few minutes for the motor to cool down, or let the drill run under no load to speed up the process. Once the normal temperature is reached, the display indication will disappear, and the drill will activate the restart interlock. At that point, switch the drill off and then on again.

Why is a different Hilti DD 150-U connecting via Bluetooth to my accessory?
- L
  laurieyoungSep 12, 2025
  If a different diamond core drilling machine is connecting automatically via Bluetooth with the used accessory, it's because several drills are connected to the same accessory. The accessory always connects automatically to the drill that enables the connection to be established fastest. Switch Bluetooth on the accessory off and then on again and connect the desired drill to the accessory again.

Why does my Hilti Drill drilling system have too much play?
- M
  Michelle WoodSep 3, 2025
  Excessive play in the drilling system can stem from several issues. The core bit might not be securely tightened in the chuck; tighten it, remove it, rotate it approximately 90 degrees, and refit it. The core bit connection end or chuck could be defective, so check and replace them if necessary. Finally, the carriage might have too much play, requiring you to adjust the play between the rail and carriage.
