Helpful Hints and Advice

Safety is essential, but so is the ease of use. By following these suggestions, you can get the best of both worlds. Try them out and see which one gets you the results you’re looking for.

You can use the extra cutting fluid while you drill. When you use a drill bit over and over, it gets warmer. If you’re going to use it for a long time, wipe away the dust and reapply the oil.

Start by slowing down the speed. The more friction there is, the more heat there is. When you drill more slowly, you can get through cast iron without wearing out your drill bits or getting too hot. It would help if you never went faster than 3000 RPM, but you can do less than 1000 RPM.

If you want to drill a big hole, step bits can help. If you use one, be careful not to move too quickly, or you could make a much too big hole.

When you use a drill bit on any metal, keep an old rag nearby. You’ll have to clean up the metal shavings and any extra cutting fluid. As many DIYers have done, sharp pieces can hurt you if you wipe them on your pants or shirt.

Always use a permanent marker to mark your surface first. This indicator will show you exactly where you want to start drilling instead of leaving you to guess.

Don’t forget to check how wide the thing you are drilling into is! If you go too far, you might hurt whatever is behind it. It would help if you always had a ruler and a leveler in your tool kit to avoid these problems.

Lastly, never drill into loose cast iron. If it’s not already attached to something, it has to have vices.
