Got a new bit! Montana Brand Sintered 1/2inch Core-cutter, and man o man I will never buy a carbide tip again, this is 10x faster and it's done 5 bottles with no signs of slowing. Much much better.

So, I chipped this one, at the botom of the hole when trying to lengthen it for the angle. :( It's not too bad, and hardly leaks and only if you tilt it all the way against the grommet, but I definitely want to work to a better standard than that.

Still, it works great! I really like it, it looks pretty classy! I found the bottle at goodwill for $2, and it came with the string :)

Two more pictures!: One, Two
(Lowering degrees of enthusiasm, I know.)

The draw is good, about what you'd expect from a wine bottle. The top is thick so it rests against my mouth pretty well and seals comfortably.

The bowl and downstem are from a new shop, and I like them better. They're thicker glass and were the same price as the others I had. Though I think I found a couple of good resources for parts online!

All in all, solid piece, I could probably get a few bucks for it.

I was in a big pinch the other day and I used some Gorilla Super Glue and it worked pretty well until I ran hot water over the bowl. It re-broke (the stem was broken cleanly off a bong's bowl) and I re-glued it. It lasted a little over a month and then it managed to re-break again after 10 different cleanings. Not bad for some random super glue that didn't even have glass listed.

To be honest, I think the best bet is just to Google something like 'glass glue'... just found this super glue which seems to have OK reviews.

go for the diamond dust bits. I just recently got a set of them and they changed my life. Well maybe not quite like that but they're leaps and bounds better than the arrow head looking ones. I got a set of 5 off Amazon for a little more than $10 and could not be happier with how they performed. Couldn't find any at my local Home Depot. The only issue is that they only go up to half an inch in diameter and the smallest downstem i've found is a tad larger than that. There is a set of bits by the same brand for like 30 bucks and they go from the next size up to like an inch and a half diameter but i'm not sure if i'm ready to upgrade to those just yet. It would make drilling holes for standard down-stems exponentially easier, but I don't do that kind of thing with any regularity. To make the holes bigger I have used a conical grinding or sanding drill bit but make sure you use water to keep everything cool (especially the diamond dust bits) and be patient. I've cracked many a bottle pretty badly due to impatience and improperly cooling the bit.

Oh and the brand is Neiko

How to make a bong out of a Hennessy bottle:

1/5th bottles seem to work best. Get a bottle, wash it out, and set aside.

Go to a smoke shop and ask for a downstem and bowl piece. Ideally the down stem will be about 6” long. You can go longer/shorter depending on the angle your hole is made at.

Once you have your downstem, take a tape measure and measure the OSD of the glass. (Outside diameter. In my case the OSD was a hair over 1/2”, so I used a 5/8” drill bit)

Once you know the OSD of the downstem, you’ll need to go to the hardware store and get a drill bit that is at least 1mm larger than the OSD of your downstem. You need a special carbide (or diamond in some cases, ymmv depending on where you go to get the bit) drill bit that is intended for going through glass. They look a bit like this.

Drill your hole. ALWAYS WET DRILL GLASS. Always. Do it in your sink with the water running, and drill at about half-speed. It will take some time to get through the glass. The angle you hold your drill at will determine where and how the downstem sits in the bottle. About a 45 degree angle on the glass where I put my downstem works well.

Once the hole is made, rise the bottle out very well, and dry the outside. Put your downstem in the hole, and use some putty to make the air seal.

Pack a bowl, and enjoy 🙂

u/TheGuyThatAteYourDog · 1 pointr/StonerEngineering

I got these diamond coated drill bits for like $10 that work like a charm. I drilled the initial hole which was too small, but because the bit is coated on the sides, you can expand it gradually. I love them and highly recommend them.

Then, there's how I was able to get it in at an angle. I made the hole and ellipse, not a circle, because I'm not using a grommet to seal it and the intersection of a cylinder and a plane at an angle i an ellipse. Then, because these drill bits can almost be used like dremel bits, I just went along the edges at the angle I wanted.

u/Norville-Rogers · 1 pointr/StonerEngineering

Okay quick PSA on drilling!


I use this style of drill bit, which are avialable in 16 and 19mm. They work great because they don't have a central point of pressure like other types, and it has file etching on the side of the bit as well as the tip. when you drill, you submerge the piece in water and allow it to fill almost all the way. I like to wrap it in a water soaked rag to dampen vibration in the bottle and to shield my hand in case of shattering. certain surfaces are harder to drill on than others, such as rounded areas and or things with texture and design. It's simply a matter of getting that established nitch in the glass to do this I demobilize the piece as much as possible under water, and at a high drill speed give my desired spot a series of sharp taps. be as precise as possible while the bit establishes a nitch in the glass. once it gets going, drill at a medium to slow speed. when you see bubbles it means that you have begun to breach through. this is a good time to stop and check your whole. at minimal speed and pressure, drill through the remaining glass and remove the displaced piece of glass. next using the etching on the side of the bit, wear down the glass on the upper outer part of the whole, and then do the same to the lower inner part of the whole. this will allow your down stem to tilt downward more. Once you have your whole you need to fit a downstem in the most airtight fashion possible. I've used puddies, sealants, glues, and such but I'm personally a fan of a good old fashion rubber grommet. If your hole is good enough, you should be able to get a relatively air tight seal and your can avoid the risk of harmful chemicals. most head shops will carry a rubber grommet compatible for downstems and you can also find them online. Hope this was helpful, let me know if you have any more questions.

Use a glass drill bit like these

Make sure to use lots of water while you're drilling to keep it cool. If you keep it cool enough you can drill a nice clean hole.

If you're feeling handy you can use a tap and die set to put threads in it to put in a downstem that wont jiggle around as seen here

Edit: Don't tap the glass itself instead fit a piece of metal which is tapped. Fix the metal to the glass with super glue

u/phs1945 · 1 pointr/StonerEngineering

If you have all the pieces I would still recommend that you use Gorilla Epoxy to fix it up. Real easy to fix and safe to smoke out of. Water resistant and won't melt from heat or solvents like acetone so you can clean it too

u/RagingScienceBoner · 1 pointr/StonerEngineering

Yes. This style of bit also works.

Looking through the options, I may get some of those diamond bits because they're a lot cheaper and come in a bigger range of sizes than my hometown hardware store. Fun side fact, the diamond bits work well for really thin, delicate pieces of glass.

u/dismayus · 2 pointsr/StonerEngineering

Is there any particular reason you're using that glass? It looks like its already fractured, and may be jagged around the edges. From the looks of it, you may be better off using a brass bowlpiece, it wouldn't look too bad either. You can usually get them at headshops. That way you would just bore a hole slightly smaller then the bowl and screw it in, no adhesive required. Something like this is what im think of:
Anywho, good luck!

u/Eresfds · 2 pointsr/StonerEngineering

ok since no one here has said it yet, yes glass drill bits buuuut, it works waaay better if you get glass hole drill bits like this, i actually bought the 14 mm but i will warn you now, 14mm glass downstems are only approximately 14mm, its closer to 14.6 or something so you give it like a millimeter so the rubber grommet can fit

u/redittttttt · 2 pointsr/StonerEngineering

Awesome! If it's your first time drilling into glass, practice a couple times on similar bottles first. Also make sure you're using a hole saw like this:

u/Harddaysnight1990 · 2 pointsr/StonerEngineering

This pipe is fine. Haters are going to hate on anything that isn't glass, when there are a great many cheaper materials that work perfectly for pipe making. I have been using brass and brass pipe screens for years, and have had no problems with it. Brass fittings are lead free, and that's the only legitimate concern. Otherwise, the pipe may get a little hot, but it has never got too hot for me to not be able to touch the pipe. I do have one recommendation, though. Get one of these off of Amazon. It's a brass bowl that will screw into that pipe and then you'll have a real bowl. You will probably need some Brass Pipe Screens for it too, but none of this is expensive, and the brass bowl comes in a set of 2, so you can have two pipes. I've had the same pipe for over a year, and it still works perfectly. And the major advantage that brass has over glass: you can drop it without it shattering.

SE DT220R 180 Grit Diamond Burr Set, 20-Piece

Use the egg-shaped bit. Hold the bottle under a small stream of cold water in your sink so that it is rolling over the spot your going to drill. Use a dremel on highest speed. Go slow and occasionally lift the bit off the glass while you're drilling. Once the bit is through the glass, use the sides of the spinning bit to sand away the glass and open the hole to to desired size. Bob's your uncle and you got a pipe. I'm currently in a pipe/bong making phase and this is my method.

I'm particularly proud of this one... Recycled Coca-Cola bottle 2-chamber glass bong

u/SmokeShrubbery · 2 pointsr/StonerEngineering

Agreed, the little "top hat" shaped grommets are great. Might also be able to use gasket maker if nothing else fits. (

u/OEMBob · 5 pointsr/StonerEngineering

I usually just use an electrical grommet in the size of the drill bit I used for the hole. If you aren't sure of the size, you can get a multi-pack like this and try some until you get a good fit.

u/Mtdewslurpee · 1 pointr/StonerEngineering

I'm gunna be a dick and say I told you so. But anyway... Here's a cheap set of bits that will last a long time if you take care of them properly.
SE DH6HS Diamond Hole Saw, 5/32-Inch by 1/2-Inch
You can cut an array of different sized holes with these.
As for the gravity bong idea you should take a look at the product called the kinkajou. It's basically a mounted glass cutter for bottles. If you've got some carpentry skills you can make a brace with your glass cutting tool to cut bottles perfectly. Honestly if you get the bits all you'll need is a hole. Here's a link to a homemade bottle cutter you can make with your glass cutter:

Bosch GT2000 Glass and Tile Set, 4-Piece

OK, I think the one I have like this is "carbide". I guess they mean tungsten carbide?

u/Daehz · 1 pointr/StonerEngineering

Thanks man :D and I used a 1/2 inch diamond drill bit and the rubber grommet is also 1/2 inch that I got at my local hardware store. Diamond Drill Bit Link

u/Palxim · 6 pointsr/StonerEngineering

diamond drill bits are useful for that, here

u/WeirdGoesPro · 21 pointsr/StonerEngineering

This! I came to suggest the Smoke Buddy carbon filter.

They are worth their weight in gold. They are about $10 a pop, but they last me about a month and a half each if I keep the mouth area clean.

Dryer sheets make less smell, but a Smoke Buddy catches all smell from your exhale. I have had people come over 10 minutes after I smoked a bowl in my living room and they couldn't tell.

u/jeska123 · 1 pointr/StonerEngineering

would any drill bit fit a standard drill? i don't have a personal drill, but i'm looking to buy a glass drill bit and borrow a friend's for a diy project with a huge belvedere bottle

i was thinking about getting these

u/chuck138 · 1 pointr/StonerEngineering

This probably wouldn’t work for dry papers but they do make really cheap machines just for that. They come in many different sizes for typically under $10. It’s the only way I can roll lol

RAW 79 mm 1 1/4 Hemp Plastic Cigarette Rolling Machine

u/reverendwrong · 6 pointsr/StonerEngineering

Absolutely! Just make sure you have either ceramic, diamond, or carbide bits otherwise you're gonna destroy all the bit heads. If you don't have them I may suggest either of these...

...they ain't the worlds best bits but the price is just right and they've lasted me at least 3 projects, and will probably make it another 3 for sure. And they're cheap to replace!

u/ConfirmedSFW · 1 pointr/StonerEngineering

I just ordered this and I'm finally gonna make my Vodka Spirit Bong into the bong it's been waiting to be transformed into. Probably gonna need a grommet and I'd like to find a way to make a perc although I'll probably buy a downstem with either slits or a tree perc

u/its710somewhere · 7 pointsr/StonerEngineering

There are other kinds/brands of bits that can do the job, but I'm a fan of these.

u/oPsYo · 1 pointr/StonerEngineering

i have a set thats a bit larger than this
main thing you have to look out for is if the bits you want will fit the chuck of the drill you are using

u/Throw_tothe_away · 7 pointsr/StonerEngineering

I start my hole with a Dremel and the round (ball) bit of a diamond Burr set found here:

Once that's through I finish up with a cone shaped 1/2" Diamond Burr set made for a real drill:

I haven't used the second ones, cause I bought mine off ebay but I used the exact dremel bits on the first link

u/JFreedom14 · 10 pointsr/StonerEngineering

$84 on

Not sure how... our CAD isn’t worth ~1/4 of the USD... this stuff always pisses me off.

Also 2 starts from 7 reviews...

Edit: from below! Thanks u/swaggercorn

u/MyLittleGrowRoom · 1 pointr/StonerEngineering

Amazon has them for less than $5, and my local tobacco shop has them for less than $3. Amazon Raw Rolling Machine

u/only_goes_on_rtrees · 2 pointsr/StonerEngineering

noooo, use this, it will be sooooooooooooooooo much faster than the carbide arrow tips

u/freedomfries5 · 1 pointr/StonerEngineering

Use an epoxy that can withstand high temperatures. i. e. Gorrila Glue Epoxy

u/MentalWarfar3 · 1 pointr/StonerEngineering

This is the set I use, I just start with a small round bit to make a hole then work my way up.

u/NUmbermass · 2 pointsr/StonerEngineering
I would try this but I'm not speaking for experience. It claims to be heat and water resistant.

u/CrayonData · 1 pointr/StonerEngineering

If you still have the other section, I would get some Loctite Glass Glue and use that.

u/CwithoutanE · 49 pointsr/StonerEngineering

And a simple Google search...tadaaa

Magic Vegetable Meat Roller - Sushi Rolling Tool Roller Magic Sushi Roller Stuffed Grape Cabbage Leave Grape Leaf Machine

u/TheHonorableTree · 2 pointsr/StonerEngineering

Buy one of these.

Attach it to a drill, and bore through the glass by letting the drill bit do all the work.
Run water on the drillbit while it's grinding through the glass, it prevent cracks from forming.

u/Electric_fuzz · 1 pointr/StonerEngineering

Rookie mistake to buy a $20 drill bit, when you can get 20 for $4

u/Henital_Gerpies · 1 pointr/StonerEngineering

I take singular, small hits and blow it all out with this contraption, as long as one is careful the only smell will be on your piece and your breath. Candles, airing the room out via a window, and not overdoing it smoking bowl after bowl will help. That thing works with concentrates too, absolutely no smell from that combo imo but usually the smelly person cant smell their own stink until its too late.
