Strong and quality tool. good material, finishing and precision

Well made, easy to use, Tight Tolerances so no drillbit wobble. A pocket drillpress for accurate drillling on flat surfaces, round pipes and dowles and corners. Just keep it oiled. Worth the money. American Made. I'm satisfied and would recommend.

Product is great. Once you get a secure it's perfect.

I do farm maintanence, and part of my job, is fixing bin augers. These augers are driven from one end, by a hub that fits over the end of the shaft, that has a bolt that goes through, coupling everything together. What happens, is that every now and then something will work loose, start to wobble, and wear out the end of the auger shaft. The fix is simple, cut the bad part off the end of the auger shaft, bolt on an extension sleeve, re-connect everything, and go. The problem, is drilling a new hole in the end of the existing auger shaft. The hole must be square and centered, for everything to fit properly. This job used to mean that I had to pull the entire auger shaft out of the assembly (some of these are 20+ feet long, and weigh maybe 80 pounds), haul it to the shop, figure out a way to jig it up in the drill press, all to drill one hole. With this guide, all I have to do, is pull the shaft out far enough to gain clearance for the drill, clamp this to the shaft, and drill the hole. Turns a 3 or 4 hour job into one that takes less than one hour. While maybe not Space-Shuttle precise, it does VERY well, guiding the drill bit straight and square. Just be sure you have it clamped securely, so it can't wiggle. The way it works, is very simple. This is a simple jig, that has a series of holes precisely drilled through it, which act as a guide for your drill bit. It is of hard enough steel, that the bits don't seem to be able to bite into it, and enlarge the holes. On the backside of the jig, a V-groove is machined, so that if you clamp it to a shaft or pipe, the jig is automatically centered, and squared to it. You are only limited to using it for the drill bit sizes on the jig, and in spaces where you can securely clamp it. However, for bigger holes, I also have had good luck using it to drill the pilot holes, and then following by carefully enlarging the hole with the proper bit, just go slow and careful. For drilling through flat objects, follow the tip I read in another review. Shine a light down the V groove, and you can look down the hole you will be using for a guide, to center the jig. It is one of those tools, that is so simple, and error proof, everyone who does any amount of drilling, should have one.

Bottom line is this is a well made little tool that aids in positioning a drill bit. It is not a substitute for proper drill press or jig. It is well made, the size of the holes appears to be accurate and it comes in a convenient protective case. Other reviewers have said it needs to be clamped and I agree clamping would be very adventitious. However this was not possible for our application (the holes for a door knocker) and it was possible to hold it tight enough to get a good result. We did experience some side rocking on a wood surface that tested flat. If the tool was slightly wider I feel it would be much better and for this reason it rates a very respectable 4 stars. It will live on for many years in the tool chest. Would recomend.

This is one of the essential tools in the world, and I wish that I would have bought one a half century ago. I’ve just finished a project made entirely of hard red oak that required precision drilling and this tool worked flawlessly. The tool fits inside my drill’s own storage case, and shows no signs of wear from using it after twenty or so 5/16” holes. Highly recommend!

Solid metal construction. Came in its own storage container (not a high quality thing, but more than adequate, and helpful). Liked the numerous size options as compared to the smaller type of device I had.

Great for drilling straight holes.

This is a great tool for woodworking when a drill press isn't available, can't be applied to the task, or is just overkill. Well-made, small enough to keep in your pocket or tool belt and to get into relatively tight spots, but large enough to hold onto while drilling, to register on the work surface, and to stabilize the drill bit sufficiently in use. You do necessarily lose some of the drill bit's capacity, and although the markings are recessed, they are small and would be easier to see if they were filled with black paint. Also, although there are center alignment marks along both sides for each hole, there is no obvious way to line up the guide in the other direction, so I don't find them useful. Instead, I just center punch the hole, slide the guide far enough up the bit to start the hole without it, then slide the guide to the work surface and finish the hole. A little pricey for what it is, I think, but it works great and looks like it should last a long time.

Grâce aux avis d'amazon j'ai acquis ce guide perçage très solide. Je suis vraiment content de cet achat qui m'a accompagné dans ma formation de menuisier et qui va m'accompagner maintenant sur mes chantiers. Toujours dans ma trousse à outils ou dans ma poche. Les perçages sont précis et droits. Vraiment satisfait de ce produit même si c'est un petit investissement.

クランプして使うと大変使いやすい。 高かったが利用価値がある。

Buena.

This does what it is designed for and make hole drilling much more accurate....
