| Drill bits aren’t cheap, but they do seem to dull quickly. Whether you’re drilling through dense hardwood or hardened steel, some drill bits seem to lose their edge within minutes of coming out of the package. |
| Instead of throwing dull drill bits in the trash, you can restore their cutting edge with a pedestal grinder. The pedestal grinder can help put a sharp point on an older drill bit, grinding the tip at the perfect angle. The result is a fast-drilling, clean-cutting drill bit that works as well, if not better, than new. |
| To be able to sharpen a drill bit it is important to understand drill bit terminology and what make it possible for a drill to drill holes. |
