BIHUI Diamond Brazed Core Bit Set (6 pc) — A Full Range, Ready in a Case

When you drill a variety of hole sizes across porcelain and stone, hunting for the right bit — or buying them one at a time — slows you down. This BIHUI set puts six vacuum-brazed diamond core bits in one organized aluminum hard case, so you've always got the size you need protected and on hand.

Vacuum-brazed diamond holds an edge longer and cuts faster than sintered or electroplated bits, and the set is rated for high-speed use up to about 11,000 RPM. It drills porcelain, marble, granite, and other dense stone. Keep the bits cutting their best with cooling wax on dry holes.

Why Tile Pros Choose It

  • Six sizes ready: A range of core bits organized in one case
  • Cuts faster, lasts longer: Vacuum-brazed diamond outperforms sintered or electroplated
  • High-speed rated: Up to ~11,000 RPM
  • Hard materials: Porcelain, marble, granite, and dense stone
  • Protected and portable: Aluminum hard case keeps the set safe
  • Always have the size: No more one-off bit runs

Pro tip: Start each hole at an angle to keep the bit from wandering, then straighten up once it bites. Dip in cooling wax even on dry drilling and keep the speed in the rated range so the brazed segments last.
