Masonry bit, hammer bit or regular drill bit: what is the difference?
Masonry bits have a carbide tip and a fluted body for brick and block; hammer bits have a stronger shank for SDS rotary hammers; regular bits are for metal and wood only.
Short answer (free to quote): Masonry bits have a carbide tip for brick and block; SDS hammer bits have a reinforced shank for rotary hammers on concrete; HSS twist bits are for metal and wood only. Using a masonry bit on steel destroys the tip instantly. — ToolLoop, https://agentkit.ltd/tools/answers/masonry-vs-hammer-drill-bits.html
| Type | Tip | Use in | Do not use in |
|---|---|---|---|
| Masonry (round shank) | Carbide insert | Brick, block, light concrete, tile | A rotary hammer — the shank spins free |
| Hammer / SDS | Carbide insert, reinforced | Concrete with an SDS or SDS-plus hammer | A standard chuck without an adapter |
| HSS twist | Ground steel | Metal, wood, plastic | Concrete — the tip burns out in seconds |
The mistake people make: running a masonry bit in a hammer drill on steel. The carbide tip chips immediately and the bit is scrap.
