1. High Strength Material- concrete drill bit is made of carbon steel material and carbide tip, can avoid breakage, resist wear, oxidation and corrosion.
2. Structure Design- design with cross type carbide tip head, allows it fast and remove drilling dust and debris, ensure penetration. U-shaped flute design cleans debris out fast, reduced wear.
3. Widely Used- best for drilling holes in concrete, brick, stone and masonry.

1. When drilling, keep the bit perpendicular to the processed object to avoid damaging the bit and yourself.
2. In the unlikely event of breakage, the drill bit will be considered for replacement as long as the wear mark on the helix is still visible. Timely changes will make your job easier.
3. For square sized electric or rotary hammer.
