Marinara Posted December 8, 2005 Share Posted December 8, 2005 Anyone got any tips on how to cut a 15mm hole with a dremel rotary tool e.g bits to use, cutting technique. I have spent the last 3 days trying to find someone to drill my tanks and am gonna try it myself. OR, if you know someone in Warrnambool. Vic who can cut holes let me know, cheers.

ViS Posted December 8, 2005 Share Posted December 8, 2005 You can buy glass holesaws pretty cheap on ebay. By the time you pay someone to drill a couple of holes, you can have the equipment to do it yourself. It's pretty easy as long as you have patience. Don't go too hard and make sure you keep plenty of water flowing over the hole and it will only take 10 - 15 minutes of light pressure per hole (I let the weight of the drill press down on the holesaw and don't push at all), and you'll get it put exactly where you want it. A 15mm hole is really small. what would you use it for? Not an overflow surely? A dremel doesn't have much torque either, which makes it a bit useless for most things.

LucifersJester Posted December 9, 2005 Share Posted December 9, 2005 I have used a dremel for the last 3 years to drill holes with perfect success and I have also recently (last 6 months) bought the glass/tile hole saws and they also work well... All I can say is heaps of water flow *I use a spray bottle* and it takes me about 4 minutes... Not long and a perfect hole at the end of it...

ViS Posted December 9, 2005 Share Posted December 9, 2005 How big are the holes you are drilling? All the holes I have drilled are 35mm or bigger. I doubt a dremel would handle larger holes would it? Maybe I'm underestimating the little tacker Link to comment Share on other sites More sharing options...
Marinara Posted December 9, 2005 Author Share Posted December 9, 2005 I have used a dremel for the last 3 years to drill holes with perfect success and I have also recently (last 6 months) bought the glass/tile hole saws and they also work well... Which one would you recommend? I can get a hole saw bit for about 20 bucks and a hand held dremel is gonna cost about 90. Then again how flash does your drill have to be to use the hole saw? Will the old GMC cut it? The hole is for a drain, but on some small tanks that I'm mucking around with. One more question, what is the dremel bit that I would need (as in product number), is it a 40 buck diamond bit? Any help would be much appreciated.

LucifersJester Posted December 10, 2005 Share Posted December 10, 2005 The dremel (mine technically isn't even a dremel brand) works really well... I have cut squares, triangles as well as circles in glass... A diamond bit is the thing you need - but don't buy a "dremel" branded one - I know at Bunnings and MagnetMart sell an accessory set (clear plastic front with red bottom) for $29.95 - $39.95 - it has 5 (if memory serves me correctly) diamond bit's in it - as well as a hell of a lot of other stuff... (sanding discs, metal cutting wheels, grinding stones etc...) This is what have used for ages - if you don't use enough water then you will grind off all the diamond grit from your bit but mistakes happen... If you can't find a set I could get one from here and post it to you if need be... With the holesaw bits for a normal drill I use a $20 drill which has variable speed - wack it on the slowest speed in the $15 dollar drill press and a water squirter in one hand and the other pulling the handle on the cheap buM drill press - 4-5 mins = one perfect hole Link to comment Share on other sites More sharing options...
