About this deal

But first, let’s understand the three general types of cabinet hardware jigs and their construction:

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. 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. 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. 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? A heavy door (often called a solid core door) should have a minimum of three hinges to spread the load and prevent it from dropping. In extreme cases, such as large oak external doors, four hinges may be necessary. Q. What kind of router do I need for door hinges?

Resources for builders

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.

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. 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.

Plans for your next project

This guide takes a close look at both types of door hinge jigs: those for full-size doors and those for cabinet doors. The two are actually quite different, so we’ll explain their technical aspects before offering suggestions for what we believe are the best door hinge jigs currently available. 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.

The Concealed Hinge Jig allows you to drill cup holes for concealed cabinet door hinges (sometimes called "Euro hinges") using just a drill. The jig positions an included carbide-tipped bit exactly at the proper position and offset, and drills to the perfect depth every time thanks to a depth stop collar. The jig is simple to use, and it ensures that you can mount cabinet doors that fit great and work properly. Most door hinge jigs are made from either injection-molded plastic or glass-reinforced plastic—also known as glass-reinforced nylon or fiberglass. The first is cheaper to produce, while the latter is tougher. 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. 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 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? 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.
