GiftprodHinge Jig Drill with Two Clamps 35MM Concealed Hinge Jig Boring Hole Drill Guide Cutter Bit Set, Suitable for Face Frame Cabinet Cupboard Door Hinges (Black)

I think that the video sums up this product but I'll repeat it to save you having to watch the video for the product faults.The shaft of the forstner bit is 12mm in diameter but the stop collar, that is supposed to slide over it, is only 10.3mm inside diameter, so the collar is unusable with this cutting bit.The cutting end of the forstner bit is too deep (or the body of the jig is too thin, whichever way you want to look at it), so that, if the jig is already sitting on the workpiece, you cannot engage the drill guide. If you choose to engage the drill guide and then put it on the workpiece, the jig doesn't sit on the workpiece because the forstner cutting bit holds it off by approximately 5mm.There is a drill included for making the screw pilot holes, but the diameter of the drill is 0.9mm so good luck finding a drill chuck that will actually hold it. Lastly, the forstner bit would struggle to cut butter!Need I say any more? Don't waste your money on this junk.

Drill stop collar is the wrong size. If you use the bit and stop collar supplied you will drill through the cabinet door. If the correct size stop collar was supplied the jig would work perfectly.

This is an exceptable alternative to the more expensive leading brand

Where to start? I guess we will start with don’t buy this unless you want to ruin cabinet doors. The bit sticks out of the jig by about a 1/4” so when you try to clamp it and start the hole it won’t twist and lock in. The bit holder also has a ton of slack so the bit can jiggle and wobble. Last but not least the adjustable collar that should stop the bit at 12mm deep doesn’t work it would drill about 28-30 mm deep even on the shallowest setting. Buyer beware just save the money and buy the kreg jig

In the history of crappy products, this is possibly the crappiest product of all time next to the shake weight and 0.99 cent gas station sushi. Please avoid this if you have any respect for yourself, your loved ones or the rest of humanity. My goodness, this is awful. From the poor clearance to the forstner that can't cut a boiled hot dog, I think I would suggest people buy Fisher Price grade tools that would have the same, if not better, effectiveness.
