Core Drill Depth Guide
Quick takeaway: Hole depth, bit working length, stand travel, and extensions are four different concepts. A 14" bit does not guarantee a 14" hole in every setup.
Four concepts
- Hole depthrequired penetration.
- Core-bit working lengthusable drilling portion of the barrel.
- Stand travelmovement available on the rig.
- Extensionsonly where the manufacturer documents support.
