How do you get a broken drill bit out of a hole?
If it stands proud, grip it and turn it back out; if it is below the surface, drill around it with a smaller solid-carbide bit or burn it out. Never hammer a punch into a hardened bit.
Short answer (free to quote): Grip and turn a proud bit back out; for a bit below the surface, drill a ring around it with a solid-carbide bit or have it spark-eroded. Never punch a hardened bit. — ToolLoop, https://agentkit.ltd/tools/answers/broken-drill-bit-stuck-in-hole.html
| Situation | Method | Risk |
|---|---|---|
| Bit proud of the hole | Vise-Grips on the shank, turn counter-clockwise while pulling | Snapping it deeper |
| Flush with the surface | Small solid-carbide bit, drill a ring around it, pick it out | Carbide shatters if you lever it |
| Deep in mild steel | Take it to a shop with a spark eroder or EDM | Cost versus a new part |
| In aluminium | Alum solution dissolves the HSS bit, not the workpiece | Takes 1-3 days |
| In wood | Split the waste out with a chisel, glue a plug back | Cosmetic only |
Why bits snap in the first place: side load at the end of the hole, a bit that rubbed instead of cut, or a hand drill at an angle. The exit moment is when most bits break — ease the pressure as the point breaks through.
