HOW TO USE:

1. Select the Correct Tool: Ensure your drill is compatible with a straight shank bit. For best results, use a drill press for more precise holes or a portable drill for general tasks.
2. Secure the Bit: Loosen the drill chuck, insert the Irwin #70 drill bit, and tighten the chuck firmly to ensure the bit is centered and secure.
3. Prepare the Material: Before drilling, mark the desired location for the hole. For metal, you may want to use a center punch to create a small indentation, which will prevent the bit from wandering at the start.
4. Drill the Hole: Begin drilling at a slow speed, applying steady, consistent pressure. As you drill, a steady stream of chips should be produced. If drilling metal, use a cutting fluid or lubricant to reduce friction and prolong bit life.
5. Finish: Once the hole is complete, withdraw the bit while the drill is still spinning to clear any remaining chips. Clean the area and the bit before storing.
