Removable device to turn a regular drill into a router

In a home workshop, a manual wood router would be useful, but in a hardware store it costs from several thousand rubles. To save money, it’s not at all difficult to turn an ordinary universal drill into a router. And this does not require expensive materials or professional skills. It is enough to be able to handle simple metal tools.

The process of converting an electric drill into a wood router

We remove rust from one end of the old profile rectangular pipe. On the wide side of the pipe, stepping back a little from the end, we mark two points for drilling holes, on the narrow side - one in the middle.

We measure 2 cm from the end of the profile pipe with holes along the line where the sides converge and make 4 cuts.

Bend the sides of the pipe with the holes outward at 90 degrees.

On the wide side with a bent edge and two holes, draw a cutting line parallel to the end of the pipe. On the narrow sides of the pipe, from the ends of the drawn line we draw diagonals to the corners of the flanged sides.

Along the marked lines we cut off a fragment of a profile rectangular pipe. In the center of the wide side of this fragment, closer to the free edge, we mark and drill a hole. We make a longitudinal slot from the hole to the end of the wide side of the rectangular pipe fragment with a width equal to the diameter of the hole.

Using a hand jigsaw, we cut out a circle of a given diameter from the remains of multilayer plywood.

We install the power volumetric plastic clamp using a coupling bolt and nut into the slot of the fragment obtained from the profile pipe.

We insert the drill into the ring of the clamp along the power belt and the chuck down, and use an open-end wrench to tighten the nut on the coupling bolt from the outside of the fragment from the profile pipe. We screw the transverse handle of the drill onto the end of the coupling bolt.

We install the drill with a power bracket on a circle of multi-layer plywood and mark the location for drilling the hole for the drill chuck with the tool.

After making the hole using a core drill and appropriate centering of the drill, we attach the power bracket from a profile rectangular pipe with flanged edges to a circle of multilayer plywood using screws.

We fix the milling head in the drill chuck, set the required reach, set the maximum speed and mill the edges of the wooden workpieces. So, a regular drill has acquired one more functionality - milling.
