HOW TO USE:

1. Select the Right Tool: Ensure your drill is set to the correct speed for the material you are drilling. Slower speeds are generally better for harder materials, while faster speeds are suitable for softer ones.
2. Secure the Workpiece: Use a vise or clamp to firmly secure the material you are drilling to prevent it from moving during the process.
3. Install the Bit: Insert the straight shank of the Irwin #31 drill bit into your drill's chuck and tighten it securely.
4. Mark the Hole: Use a center punch to create a small indentation at the desired drilling location. This will help prevent the bit from "walking" and will ensure an accurate start.
5. Begin Drilling: Apply steady, even pressure and start the drill. Allow the bit to cut the material without forcing it. Periodically retract the bit to clear chips and cool the cutting edge.
6. Finish: Once the hole is drilled to the desired depth, slowly withdraw the bit while the drill is still running to avoid breaking the tool.
