what rpm is best for drilling fused glass?
177538
go to website drillglass.com or diamondburs.net I don't know about fused glass but seaglass is start slow and inclrease to 1500 to 3000.

As a rule of thumb the more speed the better cut, provided that the adequate cooling is available. It is also a matter of how much you are willing to wait for a hole. 10.000 rpm will drill faster than 5.000 do. You can drill decently from 5.000 to 20.000 rpm

I set my dremel at max speed with glass and drill bit tip under water with some grinder coolant added. This is go keep the drill bit cool. The water also helps to reduce vibration. Remember go slow let the weight of the unit do the work. I have found with my drill press set up I am able to back the drill bit off and let it cool a second or two also. You will also some glass will seem to be harder than others and will require even slower drilling, red comes to mind. Just take your time.

I dont know what fused glass is but when drilling regular glass the higher the speed the better. Dremel on 30,000 rpm and drill with parts covered in water. I use a dremel drill press attachment which allows a precise pressure and allignment when drilling. Well worth the money for drilling glass.

I have a 3 dremel tools each with their own min/max rpm and I always set it for maximum speed - rpm doesn't matter - what does matter is keeping the glass and drill tip under water and let the tip do the work. If the fused glass is not compatible, you will soon realize through shatter marks. I hope this helps.

Unfortunately I use these drill bits for drilling stone not glass. For me I use a high RPM 10k - 25k under water to keep the bit cool and clean. I would think the same process would work for fused glass as well. For the price of the bits and if you have a piece of glass try some drilling to see what would work best for your process.

I used a variable speed drive that I plugged my fixed speed grinder into. A fixed speed grinder turns much to fast without using something to slow down the RPMs

I am sorry I have no idea, I purchased it to use with glass and fusing, it did not work for me with that project idea. Donald Martz

On the tool itself, maximum rpm is printed as 1300, which is what I think is correct. The literature says 3000rpm. I compared speeds with the PS10, which is 600rpm max and the PS11. Looking at them both running next to each other, the PS11 is about twice the speed as the PS10. So 1300rpm is the more accurate max speed for the PS11. I bought the PS11 for drilling because of the faster speed. I can drill a pilot hole with the PS11 and use the PS10 to screw in the fastener. They work well for me using them in tandem. Both are fine tools.

I used a 80 grit recylcled glass "sand." It worked really well. I'm pretty new to this also but I know that grit worked well for me. I also attempted a very course grit that didn't work very well at all.

My DWD520 is variable speed in hammer and regular drilling modes. I hope this helps, as I think it may be a error in the listing. Mine works just great as well. Keith

The purpose is to minimize wear and temperature of moving parts. I've been using 10W30: easy to obtain, does not get to thin when hot. As wear proceeds and oil consumption rises, I expect to increase the viscosity as needed (to keep oil consumption reasonable). I think 90 weight is too viscous for a new tight hammer, although OK for a well-worn-in one.

Use any standard rotary drill at medium-low speed with plenty of water for cooling. No hammer drill; that will crack any ceramic/marble/granite.

I used it with a drill press and a mill .it has to be held vertical all the time or it will dig into the work piece .it should run slow less than 200 rpm.also the work piece should not move .if you are cutting thin stuff or plastic you may use a drill. do a test run firstTarik

I can only speak for the DD750X that I have and it can grind 118 and 140 angle drills with the latter being better for tougher materials like stainless. The 750 is the only model that goes to 140, the 500 goes only to 135 so the 750 is the better choice if drilling tough materials is important to you. Clearance (relief) angle is the other important variable in grinding a drill point. The 750 does have adjustability but I don't recall exactly what the limits are right now, but it is adjustable. The best thing to do is go to the Drill Doctor website and look at the user manual and the drill angle guides they have there. Even if the DD can't get the exact geometry you're after it will give you a good symmetrical starting point for a final touch-up on a grinding wheel. Hope that helps.

I don't know, I will have to check the specifications. It it is on the tool I will respond again later.For drilling high RPM is ok, but I think you might want to drive screws a little slower, I will provide more later.Brad

Since it is variable speed it depends where you set the dial. At the lowest setting I estimate it around 500 rpm at the highest my guess is 3000. This is a very good tool for precise drilling which it what I use it for. I highly recommend it.

There is two speeds on regular and one hammer setting. Hope this helps. Great drill also

at some point with enough forceful torque, the glass will break. Then follow the previous advice.turn off power and extract with needle nose pliers

I just used the one supplied with the machine It has no speed on it just whatever your drill's speed is. hope this helps you I saw them in Home Depot and they were all the same so just buy one of those they only come in one size that I can see .hope this helps..... I think they cost around 10 or 12 $'

I would not recommend these bits for metal. For glass turn the bit at about 500 rpm and keep the tip very wet or under water. If these bits get hot they are ruined.

Its not a high rpm tool. It is a variable trigger. I use as a gasket cleaning tool in automotive with 3m disc. I wish it had more rpm.
