How to cut door hinges with a router

Features of the set and its functions

A standard tool kit for mortising locks in interior doors includes:

door, hinges, router

wood feather type drill bit (2.3 cm in diameter);

Complete lock, handles and self-tapping screws to it;

An electric screwdriver to work with these self-tapping screws;

It is desirable to prepare a marker. it will help to mark the necessary lines and contours. You can also replace it with a pencil, but such marking tool is not reliable enough. Pencil strokes are sometimes difficult to see, especially if they blend in with the background. A chisel is needed to form the area for the lock. Important: doors made of durable materials should not be processed with a chisel, but with a router. so much less effort and time is spent.

Inserting the hinges yourself

Determine where the door opens, see the convenience of opening. We put the door on its side, ideally we make angle supports for the door for it to hold itself, it will ease the work. And then putting pencil marks 20 cm away from the edge of the door. Take, screw the hinge to the door, see that the hinge is well held. Using construction knife we outline the outline of door hinge accurately and with little effort, as shown on the photo, then with great effort outline the hinge and repeat the operation with the second hinge. As a result we have a well-cut contour. Learn about the new modern ways to quickly mortise locks and hinges using special templates and carriages, which greatly help to speed up the work and improve quality. Details about the devices and templates used when installing doors by craftsmen professionals.

You can cut the hinges by yourself with a chisel by eye. You can of course more, faster with a hand router. It is not necessary to think that a cutter is a big and industrial, it is a quite acceptable tool, which needs at least a couple of diameters for different types of locks. Sherlock drills make it easy and quick to mortise door hinges, and they help a lot if you find knots and uneven wood fiber.

All about the Forstner drill for furniture hinges

The Forstner drill (cylindrical cutter), like most other tools of similar purpose, is used to create correct and neat holes in all kinds of materials. Choose such tools, which differ both in structure and price, should be chosen according to the material in which it is necessary to make a hole, as well as from the characteristics of the geometric characteristics of the latter.


One-off jobs can be accurately completed without special complicated templates, using only a parallel stop that limits the cutter’s displacement beyond the marking to one side.

But for professional work of great volume special patterns are often used. These can be both sets of templates for different configurations of fittings, and universal with dimensional adjustment.

Both self-made and factory-made ready-made variants are used.

Construction example of one of the factory-made templates:

The device makes it possible to install and move the router in the position required for exact spot drilling.

Such a device makes sense when there is a large amount of work to be done.

How to cut hinges with a router

How to mortise the hinges into the door leaf using a hand router. I should say at once that if you’re faced with a doorway, bought for a ennumber of thousand blood money, and in the hands of the cutter, which you have never held in the hands before, it is better (for your mood, and favorable family atmosphere) samomu not do it, and call a professional. A really fast, beautiful, and jewel-like mortise is obtained when the hand moves intuitively, after a few years of practice. Or to practice, plunge the hinge a few times into a bar before the finish plunge.

So. Unpack the door, just determine which side is the front and where the hinges will be, on the left or right (so that then it wasn’t painfully painful for the efforts made on the wrong side). Tape the memo to yourself with paper tape. Put the door in a comfortable position, on a stand or leaning against something.

The distance from the edge of the door to the hinge we choose to our taste. In all kinds of instructions for installation attached to the door there are a lot of exotic variants, for example, twenty centimeters on top and thirty on the bottom. But the craftsmen I have worked with, used the same distance from the bottom and top of seventeen to twenty-two centimeters. I practice twenty.

Place the hinge, trace it with a pencil. Carefully trace the outline of the hinge you have made with a sharp knife or chisel. This is to protect the door covering (veneer, film or another) beyond the outline outline from cracks and defects, which could be caused by the rotary cutter.

Adjust the plunging depth of the cutter and the parallel stop on the hand router. The long edge can be safely milled from top to bottom. The parallel stop will not let you go further than it should. But the top and bottom lines of the contour, without experience, are better machined before they reach about a millimeter and cut off the rest with a chisel. If you don’t have a good hand, routering the top and bottom lines is very likely to cause a hinge accident.

Chisel out rounded corners with a chisel or trim with a knife and get the finished loop pattern.

Insert the hinge and drill holes for screws.

Next, we attach the L-shaped curled box timber to the door. We measure the upper gap of 3 millimeters (it is possible to do it with a drill) and mark the place, where the hinges will be, on the box in microns.

Leave the parallel stop on the mill in the same position (except when the width of the box quarter is less than the thickness of the door), re-adjust the depth of cutter plunge and repeat on the box cutter the same as on the door. Screw the box and we get ready to install the product.

A fairy tale is told sooner rather than later. And that it would be done quickly and well we should invite reliable professionals. Have a nice mortise.

How to choose a milling device

Experts note that it helps to speed up the process of work by several times. Not only that, the prepared niche turns out much more even and accurate than when using hand tools. When reading the reviews, you need to find out right away if both of these parameters are provided or not. There are different types of lock mortising machines, but they are not substitutes for each other. so this point is worth paying special attention to. The vertical, aka submersible, machine just allows you to select the grooves of any depth.

FYI: this tool is useful for fixing not only locks, but also door hinges. If you want to make the edges of the recess more aesthetically pleasing, the edge (sometimes called edging) machine comes to the rescue. Specialists prefer to use a combined device. It combines both functions and eliminates the need to move two heavy machines per object. However, the cost of such equipment will naturally be higher.

It is better to use a specialized milling machine at home. over, it doesn’t need an especially high power, on the contrary, it would only increase the weight of the machine unjustifiably. But the option to adjust the speed of the cutter is very valuable for amateurs. It will help to perform all the planned works more accurately. Important: in a good machine, such a switch is placed in a safe place (even at work, you can reach there without fear) and allows you to regulate the rate of rotation smoothly, not stepwise.

Another significant factor is how far the cutter can go beyond the clamping. This indicator is usually illustrated by numbers in the model name, and expressed in millimeters. But it is still worth reading the technical documentation to rule out errors as much as possible. You should also look at whether it is convenient to use the milling machine.

location of knobs and other controls;

It’s worth running the machine before you buy it. If it is of good quality, the head movement should be completely free. It is inadmissible presence of the slightest warps and backlashes. The less noise, the better. Another thing to look at:

whether there is an additional light;

Whether or not there are auxiliary nozzles, holders, etc.

How to adjust the router for mortising door hinges

In order to quickly and accurately mortise the door hinges, it is best to use a hand router. You can also use a hammer and chisels for this purpose, but the router is of higher quality, especially if the place of incision is present, such as a knot or complex wood grain.

Let’s take the Bosch POF 1400 ace as an example.

It is better to use a cutter with a small diameter, such as 9.5 mm, so that less material has to be cut in the corners by hand. You can also use a dovetail cutter to insert the loop more snugly.

Let’s start with the router depth setting. To do this, place the hinge against the router bit and extend the router bit by the thickness of the hinge.

In order to adjust the position of the sole relative to the mill on the router body has a lever.

Next you need to adjust the position of the parallel stop.

Then place the router on the door so that the router stop is on the edge of the hinge edge.

Then we press the stop to the edge of the door and fix its position with the thumbscrews designed for it.

Make an indentation of a few mm into the future groove to check the depth of the groove.

To do this, put the hinge in it and check. If necessary, correct. That means we increase or decrease the plunge depth of the router.

Carefully make a cutting of the upper edge of the future groove, the parallel stop will not let us go further from the side line, and the ends must be very carefully managed. You can even leave some material behind and then straighten it with a chisel.

In the same way we bring out the bottom part of the hinge, and then boldly, resting on the side stop, connect the top and them. When you take out the upper part, it is more convenient to look from above as if holding the cutter against your chest and leaning over it. And when the bottom and everything else, it is more convenient to look at the stop, holding the cutter on the outstretched slightly bent arms.

Within the limits of the outline made, smoothly move the router up and down, removing everything superfluous.

Rounded corners are obtained from the router bits.

Cut them with a knife or chisel to a right angle.

Trim the ends if necessary.

Now about how to adjust the depth of the hinge cutter in the box girder.

In this case the door leaf is two millimeters wider than the quarter at the frame. In the photo the L-jointed box is on the door, and the door protrudes 2 mm from the plane.

That’s why the parallel stop needs to be offset by 2mm compared to the setting we used to cut the groove on the door. The hinge on the box must be extended, otherwise the door will “bite” the quarter and will not be able to close.

Place the router on the box parallel to the plane of the quarter and extend the router to the surface of the quarter.

With the help of the depth stop, here it is on the photo,

measure the thickness of the hinge and tighten the thumbscrew.

And now move the sole by this thickness of the loop. Plunge depth is adjusted.

It is more difficult to mill a box timber, because the sole rests on the box with only one edge. But if you do it carefully, everything is possible.

How to use a router for mortise locks

When mounting the hinges and other accessories on the door leaf by yourself you must follow all safety precautions. With the right approach and compliance with all the recommendations described above, you will get a beautiful door for many years.

Cutters are designed for milling the seats under:

Such a hand-held electric tool as a router can be successfully used to perform various types of machining of products made of wood. With the help of the machine and a set of working tools, you can not only decorate the surface of wood, but also prepare the furniture front or door for installation, using the milling cutter for mortise locks, door and furniture hinges. Of course, it is possible to perform the procedure of grooving in a wooden product and manually (using an ordinary chisel and hammer), but by using the cutter productivity of such operation increases many times, as well as greatly improves the quality of the end result.

Choice of hole for the lock cutter placed on a special device

What it is and how it is set up?

Drill bit for furniture hinges, a special milling attachment that makes it possible to work with wood and plastic substrates of sufficient width. It can be used to make the required hole in a solid panel, a hardboard panel, a chipboard or a laminated panel.

With this drill can be used to drill into solid panel, chipboard, particle board or laminated chipboard.

You can find both standard and non-standard drill with a quality certificate and warranty from reputable manufacturers.

The bit is a base with a bridge and three teeth. The middle spike is set in the center of the future circle, which is outlined with a prepared gauge, and the rest make a circular hole of the required diameter. Usually, the depth of the finished notch is about 9 mm.

The bit is a base with a bridge and three teeth.

Components that are too cheap are an indicator of a low-quality product, so it is worth considering variants with a price above the market average.

The furniture hinges for which the drill bit is used are mostly four-hinged. The hole for each is made almost instantly. When working, the drill should be held slightly tilted, not straight, so that the waste material is selected to the right depth and evenly.

Usually, the depth of the finished notch is about 9 mm.

Such a cutter is reliable and will last a long time.
