Frequently asked questions (FAQ):
1. Do I need cooling when drilling?
The XIIW core drill bit is optimized for dry drilling. Additional wet cooling is not required, but it can further extend service life on extremely hard materials.
2. How do I prevent slipping when starting the hole?
Start the core drill bit at a slight angle until it bites, then slowly bring it upright. A drilling aid is not essential thanks to the grippy diamond coating.
3. Which materials is it not suitable for?
The core bit is perfect for stone and ceramics. However, you should use specialized drill bits for wood or metal.
