Why won’t my drill go into concrete?

Common reasons a drill stops in concrete: wrong drill, wrong bit, steel, lintel, dust-packed hole or hidden services risk.

Quick answer

The usual causes are wrong bit type, a hammer drill being used where SDS is needed, dust clogging the hole, blunt masonry bit, or the bit hitting steel/rebar/lintel material.

Typical example

A DIY hammer drill that starts the hole then stops at the same depth may be meeting harder aggregate, steel or a lintel. A bigger drill is not always the answer; the material needs identifying.

Checks before hire

  • Confirm the bit is masonry-rated and sharp.
  • Clear dust from the hole and keep the bit straight.
  • Use a detector and avoid cable/pipe zones.
  • If all holes stop at the same depth, suspect a lintel, steel or hidden layer.

When to stop

  • Stop if the bit sparks, polishes the surface, hits metal, gets hot quickly, or the fixing location is near services/structural edges.
