This is the best deal in Amazon. The bits are about the same quality of those in Home Depot at $15 for a set of 20, so at this price they are an incredible deal. They last about the same as other titanium bits, and don't break easily (today I broke two of the smallest size in a handheld drill, after 16 holes in hardened steel, which is about average for titanium drills in my hand).
There are some of the 1/16 that are improperly cut, with a slightly eccentric tip that makes them unsuitable for some tasks (see pic), but it's less than one in ten of the smallest ones and I only saw one of the 3/64s that was slightly eccentric, and none of the bigger ones.
About hardness, I made eight holes with a 1/4 bit on the same hardened steel, and I could only see very slight wear on the bit under a microscope at the end (see other pic) which on the same steel caused similar damage on the DeWalt bits I've been using.
I bought this for a project as well as a flexible bit, but I didn't end up using them. I was trying to drill through the top plate in an existing wall which already had insulation. The bit ended up getting caught in the insulation, so I didn't use that bit.
That being said, the placement tool worked very well. When I first used the flexible bit without the tool, I could feel the end of the bit hitting the exterior wall. If I would have drilled it would have gone through the wall through the siding.
I confirmed this by pushing an endoscope up the wall with the bit. I was also trying to use one of those bumper balls while doing this, but it was still hitting the exterior wall. I then grabbed this tool and used it to flex the bit towards the interior.
It took a little force, but it worked great! I could move the bit so it was vertical and centered on the top plate! I confirmed this with the camera again. Unfortunately, like I said, the insulation made it so I couldn't use the bit.
Stripped screws have been a bane of my life forever but I never knew this kind of tool existed until now (thanks Internet for existing nowadays)! But this time I really needed to (very carefully) remove four tiny stripped screws (metric M3x4) from a very expensive piece of equipment.
I tried everything - rubberband trick, gorilla glue, different screwdrivers, but nothing worked. Then I got this tool. Using the #8 extractor drill bit with an electric drill at slowest speed took out all screws immediately with zero hassle. The set comes with a small case that fits all pieces neatly organized.
(I couldn't see that info in the pictures or description. In my set, the little magnet that I assume is supposed to be glued inside the extension bit holder was loose, so the drill bits wouldn't stick and would just fall out.
If you're planning on mounting lots of cupboard and drawer handles, this is a must-have. It has saved me lots of time and endless headaches when refitting my kitchen. Simple and easy to use, and dead accurate (if you take the time to set it up properly).
Has metal inserts in the sliding 'locators', so you can drill through the guide and don't have to mark the holes and then drill - saving time and reducing potential errors. Don't be put off by the plastic construction - it's perfectly sturdy for the average user.
I used it to mount 20 cupboard door handles and five drawer handles, and the finished items look excellent: cupboard handles dead-level with each other, drawer handles dead-center. Why would you spend any more than this if, like me, you're working on a one-time home project?
I needed, specifically, the .3 and .4 mm bits. I wanted to use them in my moto tool, as my hands were getting very calloused using a pin vise to cut holes. I was using them to cut hundreds of holes in a model kit for lighting, and i broke pretty well all of the .
3mm bits, most of the . 2 mm (VERY VERY delicate) and some . 4mm within the first day. But totally my fault for overestimating them. As I got more experienced, they lasted longer. And they are very sharp, too. Ask my fingers who were cleverly hidden behind the part exactly where I was drilling.
Be careful and patient, and these will do for you. This really holds true for ANY micro bits that you intend to use with a moto tool. But pin vises are not immune, either. I really wish I could have gotten a bunch of just .3mm bits somehow.
Having had purchased a cheap knock-off brand prior to this and having them fall short on the quality control, prompted me to purchase these, as recommended by a YouTube channel woodworker. These certainly are FAR superior to the stuff you get cheap from China.
The main difference is that you get 5 different sizes that are accurate with collars that are the appropriate thickness to fit North American hinges and counter-sunk holes. What I had bough from China fit the holes, but went all the way through, resulting in hole-depths that were NOT consistent.
These Snappy bits were perfect fits and did not change the depth of the holes, as they properly fit the taper of the hinge-holes. The springs are also well made and strong; a bit too strong, but I guess they're still relatively new.
I could of found alot more expensive bits than these but my project was small and needed bits in a hurry. These worked great on a very demanding solid wood job although they did not last a really long time and eventually overheated and broke.
I was expecting this and was very greatful not to have paid alot for them because I am confident that the expensive ones would of broke and cost me more for the same job. If you are using these on thin or soft material they will work fine for you.
Also I have generation 1 rotozip and they eat bits by default! These bits came very fast and I got my job done on time and that to me is all that matters. If you want perfect bits go to the Rotozip site and spend the $.
I am writing this for the review. My husband purchased the first one for our Pastor and friend. My husband who is a machinist liked it so much, that he is got one for himself. He also said that he will be giving me one of my own to use with my drill.
Looking forward to having this set to use around the home.Wife. NOTE to Husbands: If you buy this and a drill for your wife, you will decrease your "Honey Do List.".
What a difference between this end mill and the other less expensive tools available. The cut is sharp and clean and I am expecting it to last . Really worth the extra money.
After messing up two cabinet pulls with my homemade jig (one not perfectly spaced and one not fully plumb), I decided to purchase this jig. Seriously, why did I wait so long!!!??? I have remodeled 3 kitchens in the last two years and if I had know that this jig would be so handy, I would have bought it two years ago.
A few reviews mentioned that the spacers moved on them because the set screws did not fully tighten. I did not have that problem, but I did check the accuracy a couple of times when I bumped the jig during use.
I also marked on the jig with a marker (a tiny mark) so I could tell with a glance that it was still in the correct place. The jig I purchased has the stainless steel ruler so a quick wipe with some rubbing alcohol took my ink mark right off.
The jig doesn't have any instructions, but at the same time, I am not entirely sure that you need them. I simply put the cabinet pull screws through the bushing holes and attached my pull to the jig to get the placement set up and then tightened down the set screws.
I would not have been able to do 88 five inch handles the job without this jig! My wife picked a 5" handle for all of the cabinets and drawers in the kitchen, and 3 baths! I was really concerned about getting all of them even and straight.
I can't express enough how easy this jig was to use. Set it once, and do all of the doors - left and right just by turning the symmetrical jig. Set it again and do all of the same width/depth drawers, and so on.Here's a tip.
Instead of measuring the distance of the handle and trying to set the jig: Do this: 1) loosen left/right of the jig, 2) use the screws and handle to set the jig spacing, put screws through jig holes, 3) screw them in to the handle through the jig, 4) center the handle on zero, 5) tighten the jig.
You are 100% guaranteed that the spaging is right because you used the screws and actual handle holes to set the distance. My dad (a retired engineer who has built things privately and professionally his whole life) was very impressed with this tool.
This bit does exactly what it should and it even works well with a handheld cordless drill. I needed to put some concealed hinges in oak cabinet doors, and this made very quick work of creating the precise pockets in the hardwood.
It would have been a breeze with a drill press or using it as a router bit, but I did the job with a cordless drill and this bit had to be good to allow me to get away with that.
There are other bits out there that cost a lot more or a little less, but this did a great job and was worth the price I paid. Two thumbs up based on performance and price.
There's a ton of these to choose from and I decided to take a chance on the one that was cheapest AND had zero reviews, I'm glad I did! As someone that only buys highly rated products, this one delivered excellent value and functionality.
I just finished installing over 50 different knobs and pulls - 1.5", 3.5", 5.5" and 7. 5". All of them look perfect! Just take a little time measuring and they'll come out great. I don't think this would survive the daily contractor's truck/toolbox but would be ok if taken care of.Recommended.
This simple tool keeps screws from following the grain and going in at a angle. The end result is the hinge stays where it is supposed to be. Making cabinets requires lots of hinges and prior they hinges were difficult to insure they are straight.Not any more.
I used the 1 inch bit today to drill thru studs, joists and beams. This works excellent, much better and easier than my standard auger bits. This drills faster and easier since its tapered you dont have all the drag like on a standard auger bit.
All the holes drilled clean and no blow out. I would buy these again in a heartbeat and would never go back to the standard auger bit. I saw a complaint about blow out. If your blowing out the exit then stop pushing on it.
Let the drill bit drill vs.Pushing it thru. I drilled a ton of holes and not one of them blew out, EVERY one was clean.
Honestly, this is very simple. I'm a war gamer and this is a nice assortment of tiny magnets for the price. They do the job, and unlike Army Painter, these at least give you a handy little case for them.
Rating: 4 Sciencey Things out of 5
In the past I have tried to use the measure and drill procedure to mount cabinet hardware. More often that not things didn't quite line up. With a new set of expensive cabinets I wanted to avoid that problem. This thing works well for getting hardware aligned.
The comments about no instructions are true, but a couple of minutes of messing with the various elements got me where I needed to be. Also once I got the jig set up I used clamps to hold it firmly in place while I drilled the holes.
My only real complaint is the bushing holes are slightly larger than the drill size I wanted to use. Wrapping my drill bits with masking tape "cured" that for the six holes that needed drilling. If I needed to do more holes than that, I would look for a better, more durable, technique (bushings/sleeves?.
While it would have worked better with a drill press, I was able to use it with a cordless drill and pretty soft wood. I couldn't find the size plugs I needed for sale at a reasonable price. When plugging holes in wood, normally we want the grain to match, and this allows you to do that, buying a specialty tool once and making plugs to your heart's content.
Of course, you will need one plug cutter for each size plug you want to make. 5/8" happens to be a size I needed that wasn't available as a stock item most places I checked. This did the job, although it generates a lot of torque if you are hand-holding it.
Nice collection of basic bits, considering the price. Unlike the other similar drill bits sold at Amazon, this one comes with the case (the other shows the case but reviews say they come in individual sets of 5). Drilling has been clean and has met my expectations.
Obviously be careful as these are tiny bits - use them on a CNC machine and be careful with the programming. I don't recommend using these by hand as they will be very easy to break.
