Description: |
| This auger bit design is especially intended for drilling larger sizes, greater than one inch, without requiring excessive power. It uses a fine-pitch lead screw, e.g., 32 TPI, and with a relatively long straight section to pull the bit through the hole without stripping. The lead-screw has one or more flutes so that it cuts rather than compresses the wood being drilled. The auger portion is of conventional construction. |
