fast or slow speed when drilling glass?

In my experience, either. Just make sure you keep it wet to keep both the glass and the bit cool.

Yes, I reverse the drill to force the dry mix down. It speeds up the mixing.

Yes keep in mind they are VERY aggressive, and as far as glass I would use diamond burrs not carbide as carbide will be too aggressive and chip glass were diamond would be much smoother edge.

Yes! No need to use 'at a slow pace'. I run my Dewalt framer on it without any problems.

This drill works great, but it is the bits that make drilling glass, shells, or any kind of tile easier. I would recommend you buy some diamond drill bits.

worked very well--if you go slow and use lots of water--on glass bricks. ceramic is basically glass fired onto a clay substrate. I have never tried it but I do not see a problem having used the drills to go through ceramic tiles. The only glass produce which would cause a problem would be 'tempered glass'. Once glass is tempered it is doubtful that the whole piece would not shatter--that is what it is designed to do. please tell me how the project went. dantoad@hotmail.com thank you, dan

My quick answer is probably not....this little drill press doesn't have a lot of power, but I'm not familiar with drilling any kind of glass. I suppose with the right bit it's possible but I suspect even the slowest speed available on it might be too fast for glass. It's not a big investment tool-wise so it might be worth the try. I've been using this a lot for my wood items, many thousands of holes drilled at this point and it's holding up just fine. Hope this helps, good luck!

I use the round tip bit for drilling holes in sea glass. I have drilled at least 60 pieces and still using. The pointed one I use for shells and driftwood. About 30 pieces and still sharp.

There are a lot of variables that have to be taken into account. The most important ones are the hardness of the item being drilled and the size of the bit being used. Generally speaking, the harder the stock and the larger the bit, the slower the speed. If you Google "drill press rpm chart", you will find charts for most types of metal, wood, plastic, etc.

Variable speed = Trigger. "Would this work?" = Probably, however, the correct answer is that I can't really tell you based solely on the thickness of the material. Two other variable exist: the size of the hole and the quality of your bits. Most drills and bits out there can do (1) 3/8" thick hole through annealed high carbon steel, however, if you use cheap bits, and/or the wrong amount of pressure/speed, that bit won't drill another hole. I give that size hole simply because of the chuck size. If you get bits with a smaller shank and larger bore size you can do larger holes.

It's not a clear answer, but probably if you go slow, with medium pressure and keep the bit cooled with water. I used a spray water bottle and did not let the bit overheat. I also went at fairly low speed and not a lot of pressure. If you try to drill the holes quickly, the bit will wear and you will likely not last 4-5 holes. I think 5 or so holes is getting to the practical limit on porcelain, but likely be able to squeeze them out going slow and cooled.

Hi Kevin, first, SunnyNM is faster then his shadow. But it may be related to his drill model. For my concern, for a solid setup I would say 3-5 min. If you set it loose for gaining time, you will hate it. I suggest you buy a cheap drill and install the tool you will use less on it if for long jobs. You will save time. It is important the Malco be solid fixed on the drill.

One could always install a Rheostat (just like on a Router Table) and control the speed from "0" to what ever speed it will do. The low speed is plenty slow for turning or polishing anything..............if one desires very, very slow........consider the "Mini Lathe". Just suggestions.

I'm sorry...I have not motorized my grinder, yet. It takes about 3 minutes to grind a cup by hand(going steady and fast) so I would have to believe it would be faster with the drill attachment. It really is a quality grinder and I love mine...good luck!

I think it would cut a very short period. But I think with the rpms this tool runs you will have high speed glazing issues if you need to cut any legnth of time.

The speed of rotation is not drived by the trigger like drill, the speed is drived by rotary switch so the polisher start slowly (not like grinder) and at the lowest speed it's around 600rpm

I consider the lowest speed to be slow, since it mixes (for me) without sending dry ingredients air-borne, and without slinging mixtures outside of the mixing bowl. This is NOT like a blender/food processor or similar equipment, as your question references. Rather, it is designed to be used mixing batters for baked goods.
