First, this thing is not easy to use. What it does best is the hardest part - making precise cuts on both sides of your drill precisely the same. This jig is amazing at making equal cuts.What it does not do well is be an intuitive tool to use. I read the reviews and watched the videos and read through the instructions. It told me what to do but not exactly how to do it. For instance, once you dial in your primary facet, you need to dial in your secondary facet - but how much is enough? Any chart? Any guidance? Next, if you end up taking off .040 from your drill, the twist pattern will be mis-clocked if you started with straight across. You need to be smart about pre-clocking the drill a smidge or even a full shebang if it is pretty hammered. How much is a smidge or a full shebang? Exactly - You should use Kentucky Windage as your guide based upon your previous couple practice drill bits that you may or may not have tested on.Once you get a few bits under your belt, you go from being a Gomer to a Guild Member. With this tool, you will never use another dull drill bit.I started by sharpening a 1/2" drill like the instructions say. Once I finally had it dialed in (1.5 hours later and about 1/8" of lost drill bit in the form of metal dust floating around in the water), I decided to test it. I used a 10" piece of 1/8" x 2" strapping. It went through the metal making a smooth polished cut that looked like it was a machined hole. I even held onto the strapping to feel the cut and it was smooth and silky all the way through.Was it worth the gold bars? Well, figuring in the cost of the T8 and the DBS-22, you are better off buying a couple sets of carbide drills and watching another "Friends" episode. For me, this is a zen like activity that allows my brain to shift into neutral and just work with the tools with my hands. No calendar, no phones, no meetings - just a time to let my brain rest and my body go through the motions of operating a machine. It is such a peaceful tool to use. It heals me in a way that only a week on the beach in Hawaii could heal me. Just the tools and peace.Yeah, totally worth it.So, I've had the Tormek T8 and have been sharpening everything in my house and shop with an edge, and have had fantastic results---the best of any system I've ever used. Then I saw my Milwaukee cobalt drill bits that I've used so much over the years and have become so dull that I couldn't drill a hole in a wet paper bag. I've already sharpened that set of drills, and now they are so sharp that it's unbelievable! I'll say that this jig is a little complicated to use, but it's a very small learning curve and everything you need from setting the depth of the bit in the holder, to measuring the bit angle are all on the jig itself. These Swedish designers think of everything with brilliant (and I rarely use that word) design and engineering of all their products. This includes the magnifier to help you see smaller bits and the template to set the distance from the stone and angle of the base. Even the magnifier has an adjustment so you can dial it in to your exact vision.I just use the original grindstone for the drill bits--I do have the Blackstone Silicone grinding wheel but really only use that for my kitchen and hunting knives. This jig has completely rejuvenated all my drill bits (including the masonry bits) and now they will cut through even hard steel like a hot knife through butter. This jig isn't cheap, but when you pick up the box that it comes in, you'll feel how heavy the box is and what high quality it is, and that it's worth every penny. The drill bit sets I've sharpened have already paid for this jig. I've tried the high-end Drill Doctor, and this system gives much better results.This attachment works and it is easy to master with the first drill bit. The instruction book is excellent with step by step pictures.After never being able to get good results with the drill doctor and an inexpensive jig that uses the side of a grinding wheel I decided to give this attachment a try and I was pleasantly surprised.The setup on the Tormek machine took just seconds.This attachment produces a uniquely ground tip with 4 flat facets that I have not seen on drill bits before. I call it "the Tormek shape" It is similar to a split point tip but a little different as it produces a sharp point in the middle of the chisel edge where the 4 facets overlap. One can choose from a wide range of tip and relief angles. I tested a sharpened 1/4 inch bit in wood and mild steel and it performed as well as a factory sharpened spilt point bit.The bit must be aligned in the holder prior to grinding. This is a tricky operation that is done by sight. Take your time aligning the bit. This is my only complaint as aligning a bit by sight is tricky (I have 20/20 vision) even when using the supplied magnifier jig. If you are off by just a couple of degrees the facets will not be perfect but the bit will still cut with reduced durability.If you start with a badly worn bit it will be hard to align and the alignment will change if a lot of material needs to be ground off. My first attempt suffered from this but after reading the troubleshooting section of the manual I turned the bit a few degrees and reground it in just a couple of minutes to a perfect result because it was already close to the "Tormek" shape.The first grinding/ sharpening of small bits goes quickly while a 1/2 inch bit takes a while. Once you have formed a "Tormek" tip resharpening is very quick if you are not changing the geometry.This is the first machine that I have been able to use to get predictable result. As I already mentioned because of alignment by sight the process is not fully automatic but once the big is clamped the tops and rails on the attachment virtually guarantee a symmetric result. Some judgment is required when approaching the final shape but because the bit holder is so easy to lift off the machine inspecting the work is very easy.RTM (read the freakin’ manual) or you’re going to struggle. Pick it up and familiarise yourself with the jig look at the clear pictures and it’s easy to useThe manual is clear, follow it step by step and the sharpening is executed and done with ease, I started with a chunky drill that had bad geometry and in two minutes I had edge one perfect, the second took longer to develop as there was more material to remove. I went a bit overboard and needed to reset the primary a little, 4 or 5 minutes and following the manual I had a perfect drill.overall I can say this is top kit and like other Tormek jigs is well made.Price? Top level, pro machine shop drill grinders are 10 times the cost of this jig, it has limits on size but that said I think it’s value for money as it’ll last more than a lifetime and decent twist drills are not cheap enough to be a throwaway item.The Tormek DBS22 does a great job of sharpening drill bits between 3-22mm. The four-facet point produced does stop the bit wandering on smooth surfaces and the holes are easy to drill, clean and accurate.It’s an expensive bit of kit and you could buy a lot of drill bits for the money, but larger bits are quite expensive to replace and a lot easier to sharpen with this jig.Worth noting is that drill bits with hex shanks cannot be sharpened with this jig and smaller diameter bits (<5mm) are more tricky, but the kit does include a neat magnifier to help get the set-up correct. It takes a few minutes to sharpen a drill bit, changing the usual two-facet profile to a four-facet one that culminates in a point, but speed comes with practice. You can also re-sharpen broken drills as well as blunt ones, so don't throw those snapped-off drills away.If you only use smaller diameter drills (for pilot holes for screws, for example) it’s probably not worth the expense, as these are cheap to replace. On the other hand, drills of 8mm upwards are costlier and if you use larger sizes often (and own a Tormek!) it’s wonderful that you can restore them to a better-than-new condition, since the four-point geometry is far superior to the manufacturer’s original profile.Follow the instructions and view the videos on Tormek site. Works very well but takes time to set up and usse, I made the mistake of chosing a 1/2 in bit as my first as I thought that would be easy to see how it was doing and it was it just took ages since it was damaged. When sharpened with the 4 point system the results were remarkable, on wood a clean round entry hole looked almost lake a forstner bit had been used and in metal no wondering abot on the plate I used as a test. Not a quick tool to use but worked really well and tormek quality.Total impetuous purchase. I'm a joiner and know how to sharpen a drill bit....or so I thought till using this. Super results. Yes it's the cost of an awful lot of new drill bits but I can honestly say you will never want to do this again as the sharpness this will create cannot be bought. Pays your money you takes your choice. It's also a pleasure to use and not as complicated as it looks. Check out the helpful YouTube videos.As usual with Tormek this is a properly engineered tool. I had to learn the process and read the instructions a couple of times. Having learnt how to use it, it's surprisingly quick to grind an edge and also surprising how little metal needs to be removed. It does take a while to set the jig up. I decided to sharpen my drills in batches, where one drill size seems to use similar settings.
