Drilling aid for all common dowel connections with diameters of 6 mm, 8 mm and 10 mm for corner, angle, T and surface connections. Hard plastic plug-in dowel for creating perfectly fitting connections, e.g. in glued laminated timber, solid wood and chipboard. The dowel aid is particularly suitable for vertical 90-degree holes in various materials such as hardwood and tiles. Thanks to the non-slip rubber protection for smooth surfaces, safe and precise working is also guaranteed here. Optimal use in a set with the LINE MASTER precision ruler and the guide for the dowel professional. The adjustable turntable of the dowel drilling jig allows drilling of holes with a diameter of 3 mm to 12 mm. Corner connections. Step 1. Perfectly aligned dowel holes for corner fixings are no longer a problem with the dowel professionals from KWB. Simply place the dowel professional on the front edge. It is important that the zero point of the dowel professional, i.e. the position of the drill bit, is placed in the middle. Then you can start with the holes. The image is an example with a material thickness of 30 mm. Step 2. Board 1 (bottom part) and board 2 (side part) are now laid together and clamped with a ferrule. For flush and straight corner connections, the push button included in the delivery is now in play. Slide them into the parallel stop. Now use the dowel professional so that the tip of the dowel fits into the previously drilled dowel hole. And off you go. Repeat this process for all planned drill holes. Step 3. Next, insert the wooden dowels, glue them and connect them if necessary. Step 4. The orange connection is already created. For the complete shelf structure, repeat steps 1-3 for all floor and side sections. Surface connection. Step 1. Now it's time to install the shelf. To do this, place the dowel professional back in the center of the shelf and drill along the front edge. Then mark the desired distance between the shelves and the side panels. Step 2. Now, overlap the shelf and side panel so that panels 1 and 2 are flush with the sides. The parallel stop is not required for this step and can therefore be removed. The push button is now inserted into the front of the rail provided by the dowel professional. Place the zero point of the dowel professional at the previously marked location and insert the tip of the button into the dowel hole in the shelf. Now you can drill again. Whether it's one shelf or five, repeat this step as needed. Step 3. Finally, insert the dowels into the holes and connect. Step 4. The orange connection is already created. Repeat steps 1 to 3 for all shelves and the shelf brand is ready for use. Links Example: In the following example, boards 1 and 2 are to be connected with dowels. Step 1. First, boards 1 and 2 must be clamped and flush (see image). Position and drill the zero point of the dowel professional in the middle of the front edge of board 1. You can repeat this step several times if necessary for different dowel holes. Step 2. The dowel holes are now drilled on board 2. To do this, the push button must be inserted into the dowel professional, as shown above. If the tip of the sweeper is placed in the drill hole of board 1, you can drill. Step 3. Then insert the dowels into the holes and connect the two parts. Easy drilling on a smooth surface. Non-slip structure. Thanks to the two rubber strips on the underside, the dowel professional stays firmly in place, even on smooth surfaces. Dead holes in tiles are no longer a problem. Practical tip for stone drill bits. Note: Stone drill bits do not fit into the opening intended by the dowel professional, thanks to their hard metal plate on the tip. Therefore, you should always pass the stone drill bits through the dowel professional from below and tighten them in the drill. Drilling is no longer a problem. Thanks to its innovative design, the drill bit always ensures that the drill bit is inserted straight into the material.
