Whats the best way to drill thru a boulder? depends on the composition of the boulder. anything from a star chisel to a masonry bit to a diamond bit. What is your goal? a good substitute for this might be hypertufa fake boulders that are plumbed as you like. good luck. -- be safe. flip Verso l'esterno! Verso l'esterno! Deamons di ignoranza. |

The best place he found was the local stone masons, they had the right bits and water cooled setup. David |

Drill hole in rock?
Generally speaking, the best way is with a hammer drill but it all depends
in what size hole you need, what type of rock it is and how deep the hole must go. If it is brittle stone (slate, marble etc.) a hammer drill will most likely shatter the rockand you will have to use a regular drill and masonry bit. If you want a hole bigger than 1-1/2 inches, you will need to diamond drill it. Most industrial drill bits can be extended to fairly long lengths once the hole size is bigger than 1/2 inch. Your best bet would be to gather your info and call an industrial supplier or industrial rental house. Most of them have drills and bits for almost every type of stone. If it's only one stone, renting the drill will be the cheapest and you can most likely rent the bit as well. Try to stay with the larger rental companies as most of them have been trained by the companies that sell them the equipment to rent (Hilti, Hitachi, Bosch etc) and have books on hand to help select the best bit for your hole. However, if your locally owned rental shop may be able to help as well if they handle industrial stuff. Happy drilling. -- ******************************************* To reply via email, remove X80 after mcdoste in my email address. ******************************************* "Pat Keith" wrote in message ...

I have drilled various types of boulders and concrete by using a simple tip:
Get a spray bottle, fill it with plain water, and set the nozzle to a solid stream. NOTE FOR THE FOLLOWING: For safety, use a cordless drill or a GFI protected circuit for a corded drill. Start drilling with a regular masonary bit while an assistant carefully sprays water at the tip of the drill bit . It goes through like butter. I was amazed the first time I did this and haven't had to replace a masonary bit since! RR |

I agree with mcsteve. I rented a hammer drill. Good thing I paid the extra $3
for the insurance because I broke two bits! Those bits would have cost me about $50 each to replace. If you decide to have someone else drill it for you, you might try a cemetery monument company. Unlike stone masons, monument shops are everywhere. Good luck! ~ Gary |
