Kreg KHI Concealed Hinge Jig, Blue

Product Information

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.

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.

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.

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? 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. 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.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? 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. 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? Calling the Everbilt template a cabinet hinge jig is a bit of a stretch, but as a low-cost way to mark out cabinet hinge positions, it works fine. It also includes the necessary Forstner drill bit, though not the 1/16-inch bit for hinge retaining screws. 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 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. 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 body is manufactured from glass filled nylon and has a central hole for mounting the drill guide and the 35mm TCT drill bit. The two indexing cams rotate through the numbers 3, 4, 5 and 6. The number settings relate to the distance from the edge of the door to the centre of the hinge hole. Once the hinge hole is drilled you can then select one of three pilot hole positions to drill the 1.5mm pilot holes for the fixing screws. 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.Cabinet door hinge jigs are simply held to the inside of the door using any convenient woodworking clamps. Ratcheting types are convenient because they are easy to use one-handed. Two clamps should be employed, one either side of the cutter guide, to ensure that the jig can’t twist. 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. 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. There are a number of cabinet hinge jigs available that mimic the high-quality Kreg model described above. The BI-DTool has a few features that set it apart from many low-cost rivals. It is made from engineered plastic—a synthetic resin noted for increased durability. Cams provide the usual offsets at 3mm, 4mm, 5mm, and 6mm, and there’s a depth stop so the jig can be used for framed and frameless doors. 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.
