Recommended drill speeds

If you're unsure of you drill's rpm, just run it at the slowest setting. You are trying to avoid overheating the bit and what you are drilling. Too much heat will dull the bit and mess up your holes. Use cutting fluid or oil, this will also reduce heat and keep the bit sharp. Always wear eye protection when drilling.
