Yes — they wear over time, especially when used on very hard materials or without cooling.

Use a slow to medium speed with steady pressure. Too much speed generates heat and dulls the tip quickly.

No — masonry bits are designed to handle concrete as well as brick, block, and stone.

Yes — hammer action chips the material as you drill, making the process faster and easier on the bit.

Yes, but for best results use a hammer drill or rotary hammer. A standard drill will work but will be slower and may overheat.

Not effectively — use carbide-tipped masonry bits for brick.

No — they will overheat and dull quickly on masonry. HSS and titanium bits are for metal and wood.

No — masonry bits are not designed for metal. Use HSS, cobalt, or carbide-tipped metal bits instead.

Yes — masonry bits work on rock, natural stone, and drywall. For stone, go slow with steady pressure and cooling if possible.

Yes — a standard HSS or wood bit will dull quickly or fail. Use a carbide-tipped masonry bit for these materials.

Yes — many masonry bits are silver or gray and will work on concrete, brick, and block.

Color varies by manufacturer. Identify masonry bits by their carbide tip shape, not the color.

They can be either. Color is not the definitive guide — silver or gray bits are often uncoated carbide tips, while black bits may be coated for corrosion resistance. Always check the tip design to confirm it’s for masonry.

Masonry bits have a distinctive arrowhead-shaped tungsten carbide tip and a slightly duller, sometimes silver or gray finish. The cutting edges are wider than the shaft, designed to chip rather than shave material.

Wet drilling is better for bit life, cooling, and dust suppression; dry drilling is more convenient but harder on the bit.
