This little jig is carved out if a block of solid aluminum. It has a very nice finish with easy to read indicators. You will have your cabinet door hinges installed in half the time.

Pros:- Bits included (see picture)- very good build quality- easy to use (once you learn it)Cons:- No instruction manual- Needs to be taken apart to fit in case- knob drill holes don't have all options

My husband is a handyman and needed this for work, he says it's durable and does what it's supposed to do, good for the price, he's happy with it

This review is for: YAHEEDA 35mm Concealed Hinge Jig,All-in-one 1/4 inch Shelf Pin Jig, Aluminum Drill GuideOk so I consider myself a professional with regards to cabinetry. I bought this because I thought it might save me some time when just fixing or installing one or two doors in a kitchen. Well. Not really. It looks pretty on first sight. It is a nice neat package.The good:The base plate and all the pieces that come with it in a neat package. The baseplate looks very high quality.I like that they include a forstner bit with the set and depth stops to prevent drilling into the next cabinet!The spacing for the shelf pin guides seems pretty accurate and all you need is a clamp and you can install a new shelf in minutes.The Bad:First and foremost there are no instructions. I figured out on my own (without watching the videos provided on amazon product site) how to use it. At least most of it. I think having a detailed instruction set is better than watching a couple of speed through it videos.Next, the machining and tolerances need some work. The shelf pin guides have tailings that prevent the drill pits from going through (look at the pictures I posted). Admittedly, one can simply put them in a clamp and run a drill bit though to clean them up. The plate itself is rather nice but all the other threaded inserts/guides are less than quality. Machining marks, tailings, and burr's in a few threads give an overall impression of a rushed product and little quality control.If you want your off-sets to be accurate you may need to machine your own thumb screw guides. I used the included guides but consistently had 1.25-1.80mm over (I used my digital caliper to measure the distances). Depending on your hinge hardware they sometimes have adjustments that can take care of this.There is some slop in the guide for the forstner bit. The shaft of the forstner bit is 11.80mm OD and the bushing (no bearings like they said) has 12.37mm ID. Allowing for quite a bit of deflection.Lastly of the bad stuff, the screw placement guides on the sides of the red hinge hole jig do not match my hardware as you can see in the picture I had to "lower" my hinge to get the screw holes close to matching. I suppose that it depends on the brand of hardware you are using. I think using the template with the hardware might be better in this case.Overall:You can make the package work with a bit of elbow grease and I think it might be worth it for a handyman or cabinet installer who doesn't want to carry lots of tools and jigs to fix one or two doors on site.The quality compared to value... I think this set is a bit overpriced. There are other products out there.

This is second jig of this type I have ordered. The first was pretty, but didn't work. This one won me over right out of the box by meeting the basic test of doing what it is supposed to do.It's not all sunshine, though. The product is advertised as having a bearing to guide its Forstner type bit, but in fact has only a bushing, and that has a bit of excess lateral play. There are zero instructions included with the product, so you are pretty much left to your own devices to figure out how it works. (The video on Amazon helps.) Also, the shelf pin drill guides are poorly finished and will resist your initial attempts to insert the provided bit. I worried that I would dull the bit right out of the box trying to ream out the guides with it.Still, this product will work to install many types of Euro style hinges and to drill shelf pin holes. It is not elegant, but with patience and some slight modifications, it will do the job.
