Questions about this product
- Will this core bit fit my drill?
- It uses an M14 thread, which is standard on most angle grinders. To run it on a rotary hammer or regular drill, you'll need an M14 chuck adapter. Check that your tool's spindle matches M14 before buying.
- Do I need water when drilling with this bit?
- Wet drilling is recommended for porcelain, granite, and marble. Water cools the diamond segment and keeps dust down, which protects the bit and gives cleaner holes. The open-center design also helps clear debris as you cut.
- What hole sizes does this cover?
- The range runs from 6mm up to 110mm in diameter. Note this listing is for one piece, so you pick the single size you need rather than getting a full set. Confirm the diameter on the product page before ordering.
