FAQ's: Masonry Drill Bits

Neither — M35 and M42 are cobalt steel grades for metal. Masonry requires carbide tips.

Neither — both are for metal. For masonry, use carbide-tipped bits.

Any bit with a tungsten carbide tip designed for drilling concrete, brick, block, or stone.

Yes, with a masonry bit, but expect slower progress compared to a hammer drill.

Possible causes: wrong bit type, dull bit, drill set to reverse, or too little pressure.

Insert the shank into the chuck, tighten it securely, and ensure the bit is straight before starting.

It’s possible but slow. Use a masonry bit, start small, and work up to your final hole size.

Use a sharp carbide bit, avoid hammer mode on delicate brick, and start at a slow speed with light pressure.

Match the bit diameter to the anchor or hole needed, ensure it’s carbide tipped, and choose the right shank for your drill.

Typically a 7mm bit, but always match the plug manufacturer’s recommendation.

A high-quality carbide-tipped masonry bit. For old brick, use a slower speed to avoid crumbling.

Carbide-tipped masonry bits or diamond-tipped bits for very hard stone.

Solid carbide and premium diamond-tipped masonry bits are the hardest and most durable.

Carbide-tipped bits from brands like Drill Bits World are reliable for both brick and concrete.

SDS bits have special shanks for SDS hammer drills, allowing more powerful hammering and quick changes. Standard bits have smooth or hex shanks for regular drills.

Masonry bits have a carbide tip for abrasive materials; HSS bits are hardened steel for metal and wood.

The tungsten carbide tip and wide cutting edges are designed to crush and chip hard materials rather than slice them like a wood or metal bit.

Yes, but you need a bench grinder or diamond wheel. Hand sharpening is possible but less accurate.

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.
