It is easy to be critical, but for a one-off job, or for someone who has a pillar drill to set depth, the Everbilt does the job at a fraction of the price of most competitors. The Concealed Hinge Jig consists of a glass-filled nylon base with a hole that receives a drill guide. Indexing cams ensure that the jig positions the bit to drill a hole at the required offset — which is dictated by each hinge — and a built-in stop collar ensures that the cup depth is correct every time. There are even holes that you can use to guide a bit for hinge screw holes. The Concealed Hinge Jig comes with a high-quality, carbide tipped bit to ensure great results. This type of door hinge jig creates a round-cornered cutaway in the door edge, and suitable round-cornered hinges are widely available. However, door hinges were traditionally square, and when refitting a door to an existing frame, it will often be necessary to cut away the rounded area. This can be done with an ordinary woodworking chisel, but corner chisels specifically for the purpose are available.

The Everbilt jig is basically an L-shaped piece of transparent plastic that is held against the door edge. Holes allow pencil marks to be made for the hinge and retaining screws. The jig is then put aside and the relevant holes drilled. Any adjustment for offset will need to be done manually, which could lead to errors creeping in. The Milescraft jig will fit 1⅜- and 1¾-inch doors as well as hinges from 2½ to 4½ inches, in ½-inch increments. With the main frame and templates, there are nine pieces in the kit. While this can seem confusing at first, each template is marked with the appropriate size or function.

How the hinge jig is set up will depend on the type of jig. Some door jigs clamp to the side of the door, while others use locating pins and screws. Cabinet jigs usually need to be held in place using ordinary woodworking clamps, which will not be included. To ensure accuracy, it is important to follow the instructions that come with the jig. Q. How many hinges should a heavy door have? In addition to the 35mm offset cams, a pair of 26mm cams is also provided. These allow the BI-DTool jig to be used for smaller hinges, though the required cutter is not included. Unlike the Kreg, there is no scale on the edge to help with alignment. Additional clamps are required to hold the jig in position, but that’s typical of this kind of jig. A 1/16-inch drill is provided for retaining screw holes, though care is needed as this can easily cut into the plastic guides on the jig, thus reducing their accuracy.

The Concealed Hinge Jig takes the guesswork out of installing cabinet doors using concealed hinges. This economical, easy-to-use jig ensures accurate hinge alignment, so you can install doors that fit great and work well. Plus, the Concealed Hinge Jig works with an ordinary drill and the included carbide tipped bit.Cabinet hinge jigs almost always include the Forstner bit required to drill the flat-bottomed hole for the main body of the hinge. They may also include a smaller drill for the retaining screws. The guide above will prove useful in finding the right jig for full-size interior and exterior doors as well as cabinet doors. Those who want more info or clarification about these tools may well find it below in answers to some common questions about door hinge jigs. Q. Is there a tool to cut out door hinges? Fixed jigs that are initially appealing due to price and the ability to skip measurements. But that makes it less flexible and accurate for perfectly centering your holes. This concealed hinge drilling jig removes the guesswork when installing cabinet doors. It is extremely simple to use and it guarantees accurate hinge alignment, allowing you to install doors to a perfect fit. With the exception of a cordless drill no other tools are required as it comes complete with a 35mm tungsten tipped hinge bit with depth stop collar, 1.5mm pilot drill bit and location pin.

A router bit is required with full-size door hinge jigs, and one is often included. Shank size will be either ¼ inch or ½ inch. Neither is better than the other, but the size will determine the kind of router used. Some ½-inch routers include a ¼-inch collet as an option, whereas ¼-inch routers cannot use ½-inch bits. Even skilled carpenters usually turn to a door hinge jig to ensure the fast, accurate positioning of door hardware. This tool helps obtain the precise measurements required for the task of installing doors. Most are simple enough to be used by even relatively inexperienced DIYers, and most are very affordable—especially when compared to the cost of ruining a door. Clamp-on jigs like the Kreg and a dozen other varieties of mostly fixed-hole jigs. While these jigs are suitable for smaller projects, getting that perfect 31/64 alignment that is surprisingly required on highly symmetrical installations is more challenging.Buying a door jig is the easy option, but with care, it is possible to make your own. In fact, for cabinet doors, a jig isn’t strictly necessary. If you can measure and mark accurately, hold the drill vertically, and judge the depth of a hole, then a Forstner bit of the appropriate diameter to match the hinge is all that is required. Owners of pillar drills will find the task easier, but a portable drill and a steady hand can get the job done. The jig can flex if too much pressure is applied when routing, so care is needed. Unfortunately, the included router bit is not very good and soon loses sharpness. Those with numerous doors to hang may wish to invest in a better cutter. The amount of adjustability provided by door hinge jigs depends very much on the type. Very basic cabinet hinge jigs are simply used to mark hole positions, and any adjustment is manual. More advanced models have rotating cams that give different spacings from the edge of the door. These jigs are usually one size to suit the hinge being used—either 35 millimeters (mm) or 26mm—though some can accommodate both. There are removable corner inserts, so the Ryobi jig can be used for round- or square-cornered hinges (though the latter will still need finishing manually with a chisel). A high-quality router bit is included, as is a self-centering drill bit for making the actual hinge holes. Both bits are conveniently stored onboard the jig body. Durability is assured by the cast-aluminum construction. For transportation, the jig is dismantled into two pieces, and it comes with a carrying case. A guide bush for the router cutter is included, though the cutter itself is not—rather disappointing given the Trend door hinge jig’s high price.
