Frequently Asked Questions

Q: What materials can the pagoda step core drill bits cut through?

A: These carbide alloy step drill bits are designed to cut through 9+ surface types, including glass tiles (as thin as 6 mm), granite slabs (up to 80 mm), marble, ceramic tile, and reinforced concrete — making them highly versatile for both home renovation and professional construction applications.

Q: Do I need a special drill to use these step core drill bits?

A: No special equipment is needed. The universal shank fits most standard corded and cordless drills, so both professionals and DIY enthusiasts can use them right away without any additional adapters.

Q: How does the stepped pagoda design improve drilling performance?

A: The progressive 20 mm, 35 mm, and 50 mm step increments allow the bit to gradually expand the hole in stages. Combined with the multi-layer drill tip and three-stage expansion design, debris is cleared up to 50% faster than standard core drills, resulting in cleaner holes and significantly less edge chipping on delicate surfaces like glass and marble.
