You're likely hitting the tool's electronic protection system. It's designed to shut things off to prevent damage.
- Ease up on the pressure. Let the drill bit do the work.
- Check your clutch setting. If it's set to a low number for driving screws, it will disengage under heavy load. Turn the collar to the drill icon for maximum torque.
- Make sure you're using a sharp bit appropriate for the material.
If that didn't work, your battery might be the issue. A low-capacity or old battery can't sustain high power demands. Try a higher capacity ONE+ battery, like a 4.0Ah or 5.0Ah model.
If it still cuts out immediately with a fresh, charged battery, the internal protection circuit might be faulty. That's a service issue.
