Best masonry drill bit sets according to redditors

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 🙂

Every shop or serious mechanic should buy this set. It has saved me so much time and money dozens of times. Just go slow with carbide cobalt drill bits, they shatter easily.

here's one of the higher rated sets on amazon and seems like a good place to start

Edit-fixed the link! 😊

Just go but an easy out set.
IRWIN Screw Extractor/ Drill Bit Set, 10-Piece (11119) https://www.amazon.com/dp/B0002NYBH8/ref=cm_sw_r_cp_api_i_GK.BDb32A3JAT

This might be a better set.

8 piece Screw Extractor Set,Damaged Screw Broken Bolt Water Pipe Remover Set By Nizzco https://www.amazon.com/dp/B075TY8Y87/ref=cm_sw_r_cp_api_i_m0.BDbDKJD770

Get the tools in the picture. They're great, and relatively cheap.

Yeah that hole doesn't look too good TBH. Hopefully it didn't damage the threads. The smallest one in the kit I showed you has a minimum of 2.5mm but it should still work on the 2mm screw. You can also find a spare 2mm allen key you don't need and use the strongest Gorilla glue you can find and glue it onto the screw. Slowly try to unscrew it after an hour or so. Take it to your LBS and see if they can help. There's also this which goes as low as M3

Edit. Just looked at the other angle pic you posted. Screw extractor most likely won't work. Try the allen key method.

> Kannst du was empfehlen?

Kauf halt keinen 6V Minischrauber und kein Bitset von Lidl :)

Habe selber diesen Schrauber hier und das dazu passende Bitset und bin voll zufrieden. Der hat genug Drehmoment um auch kleinere Bohrarbeiten zu erledigen und schraubt schneller als ich gucken kann. Die Bits halten sehr gut bisher - und darum gings mir bei dem (!) auch hauptsächlich - Schrauben kannst du nachkaufen bis du grün wirst, wenn aber das Bit rund ist weil es aus verchromter Butter gemacht war kannst du nicht weiter arbeiten.

Rotary hammer

General outline straight cuts using a wet tile saw, then use tile snippers for countouring.
There's a lot of options for drilling the holes.

Get yourself some masonary bits for your drill, mine were about 15$ on amazon. hit the thrift shop/yard sales etc. anything you like can be a pot. shallow pots are better than deeper for succs. i use egg cups, candy dishes, cannisters sets, flower bowls, serving dishes, soup bowls, etc. your choices are endless and it is a way cheaper option, especially if you have 50 or 60 of these things like i do. i also got glass bits for my drill and so have some really pretty glass pots as well.

if you want a store option, terra cotta pots are cheap and you can find them in any big store like walmart etc. sometimes the thrift shop has those too...and if they are a bit grungy, i wash them really good with soapy water to ensure no parasites, let dry then use a sanding block to sand away the grime or discolouration.

if your succs can stay outdoors, you can use concrete blocks (or make concrete pots). drift wood etc.

edited to add some links/info.

EDIT Again! here are some of the great pots i've thrifted and drilled. https://imgur.com/a/4ztbWmn

I've used these to drill through glass and tile. Take your time and they get the job done. Its only four holes after all.

5 Piece Concrete Drill Bit Set,... https://www.amazon.com/dp/B07FDHDZ3T?ref=ppx_pop_mob_ap_share

Have water running over the drill bit during the process. Prevents blowouts and extends life of bit.

Start the drill slowly and move up to a higher speed but don’t squeeze the trigger all the way on your drill. Don’t use an impact driver.

You drill into it with a reverse (left handed) drillbit, running your drill in reverse. That will probably bring the bolt out, but if it doesn't you use an Easy Out screw extractor to screw it out. Here is a kit with both left handed bits and extractors. You can get individual tools at a local hardware store. Soak it well wit PB Blaster first.

I think maybe it's this one

You could use something like this kit, i have one and it very useful. Just make sure you measure your binding post size and cross check to see if this kit comes with the size you need.

IRWIN Tools Hanson Spiral Extractor and Drill Bit Set, 10 Piece, 11119 https://www.amazon.com/dp/B0002NYBH8/ref=cm_sw_r_cp_apa_CPgQBb1RK76C6

Got a picture? Maybe a left hand drill bit along with a screw extractor bit, if you have room?

Something like this: http://www.amazon.com/Irwin-Industrial-11119-Extractors-10-Piece/dp/B0002NYBH8 (but they do make better ones out there too)

Assuming the head is stripped (rounded) and it's not the threads, I'd use this style of broken bold extractor. That is assuming you can fit it on.

If you've got nothing at all to work with, then you can use a spiral-flute type broken bolt extractor

These are basically like big reverse-threaded screws that screw in counterclockwise (so lefty-tighty, unlike normal bolts/screws) that let you put enough torque on the bolt to remove. No sawing is necessary, you just have to drill a hole into the stripped bolt more or less on center.

If it's the nut on the hinge pin, I'd just use a small drill bit and drill several holes vertically and then crack it with a chisel (protect the door when you do this.)

Practically everyone carries door hinge pins and mounting hardware. Jeep dealers will have them, as will the major online parts places (4WD, quadratec, etc.)

> carbide masonry bit

Did you get a pointed one (like this or a regular one like this)? So many cool pots have no drainage holes.

This is what you're looking for, screw extractors. Cut the head flat, center punch, drill out, then use the left handed extractor bit to remove the bolt

I did this to a valve cover bolt or two, over tightening them to avoid leaks. It sucks, but it happens. These solve the problem.

Note: some WD-40/penetrating oil and heat can make the process go easier, as mentioned elsewhere in this thread.

Thanks for the info! I think the foamboard adhesive is PL 300 from Loctite, but Lowe's also has something called Loctite Power Grab which is also supposedly safe for foamboard. I'll probably go with the PL 300 because that's what I've read about the most.

I'm thinking about taking a hammer and chisel (or rotary hammer w/ chisel bit?) to knock down some of those rough areas. There are just so. freaking. many. hahah I was also planning to brace the foam against the wall with 2x4's. I've contemplated, but really don't want to spend the money, using a couple of these on each sheet of XPS, too.

I was a little worried about condensation forming between the foam and the concrete if there were voids, but I suppose as long as there is a good seal around the perimeter of the foam that's the main thing.

Thanks again!

I got this last year as I was in the same boat as you and wanted to b*ifl. The drill is ridiculous and overkill, but when I drive in 1-5/8" drywall screws... they don't know what hit'em.

A few things to look at.


If you already have a drill you need to know what kind of drill bits it will accept.


These have a 1/4" hex that basically any drill will take: Drill Bit 1

Where these are a smooth cylinder meaning you'll need a drill that can clamp down on them: Drill Bit 2


You don't really need an anchor if you use something like these, but they are likely over kill: Concrete Screw


If you are just hanging pictures or something light this might be a good option: Full Set


Lastly, a drill that has the hammer function would help greatly but isn't required.

I like these personally, and using a hammer drill with a 1/4 bit goes very fast

  sorry for formatting, i've seen plenty of these posts this is the first time i took time to actually look up evrything i've purchased.
  
  Edit: Some formatting. added velcro :P

I am sure there are other ways but I use carbide glass drill bits. They are a bit pricey ( 10-20 dollars USD depending on the size at home depot), but they do a really good job and are designed to cut glass so you have less of a chance of cracking it. There are cheaper sets out there on Amazon but I have found you have to replace them much more frequently and they just don't hold up as well.

hope that helps!

Or is this closer to what you're thinking?:

straight fluted easy out.. a set of tap sockets.. tap sockets are specials for use with threading taps.. there is a chance one will fit the straight fluted easy out..

tap sockets... https://www.amazon.com/Lisle-70500-Tap-Socket-Set/dp/B0002SRFOE/

so you can get a socket on it way down the spark plug hole..

chances are somebody cross threaded the spark plug and just cranked it in till it almost broke.. or you exerted enough force when it seized taking it out.. that you snapped the spark plug in half.

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

There are special drill bits designed to drill through ceramic. I bought these: https://www.amazon.com/dp/B001GNC8RI/ref=cm_sw_r_cp_api_Ev8FybXJ3YC1D

I use a DeWalt case that has compartments. It came with a masonry drill bit set. It's slightly larger than the one you have but it has locking compartments.

I'm in the US, but judging by the photo of that jigsaw here it appears to be a standard T-shank blade.

For example, this set.

I like this set, all the extractors come with a matching left handed drill bit.
http://www.amazon.com/gp/product/B0002NYBH8/

I've had success extracting a broken bolt with this kit: https://www.amazon.com/gp/product/B0002NYBH8/

I'm sure any similar product will work.

I have these Irwin left handed bit/extractor set. I generally end up using them for all kinds of holes, even when it's not a bolt or I'm not trying to extract it, they just seem to cut really well, especially at the price point. I think lowes or home depot carries them too.

https://www.amazon.ca/Irwin-Industrial-11119-Extractors-10-Piece/dp/B0002NYBH8/ref=asc_df_B0002NYBH8/?tag=googlemobshop-20&linkCode=df0&hvadid=292995173425&hvpos=1o2&hvnetw=g&hvrand=13370702493849758587&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9000649&hvtargid=pla-613176131032&psc=1

I own this set, http://www.irwin.com/tools/screw-bolt-extractors/10-pc-spiral-extractor-drill-bit-set-in-metal-index / https://www.amazon.com/Irwin-HANSON-Spiral-Extractor-11119/dp/B0002NYBH8/ref=sr_1_3?ie=UTF8&qid=1521322834&sr=8-3&keywords=irwin+screw+extractor+set&dpID=410DHljAW2L&preST=_SY300_QL70_&dpSrc=srch

and have used it once or twice. What I like about this one is the left handed drill bits. When you use the drill bit to round out the screw head, the left handed drill bits might just grab the screw and unscrew it for you.

https://www.amazon.com/dp/B0002NYBH8/ref=cm_sw_r_cp_apa_i_eCy4Cb467MDW6

I like these kinds of kits, I have one like this (not sure which brand). Those reverse drill bits sometimes work better than the extractors.

Get a screw extractor set from Amazon. Just make sure to get one that comes with left hand drill bits. You can often get the screw out just with the left hand bits before even needing to use the extractor.

This is a good kit if you want a variety of sizes for anything like this in the future:
https://www.amazon.com/dp/B0002NYBH8/

Something like this might help. I know how small that roll pin must be, but I am not certain one of these tools will be small enough for the job. Might be worth it, though. Otherwise, a trip to a professional gunsmith might be in order. Good luck!
