A friend suggested: sharpening drills without special tools
Accumulated more blunt drills that, so I decided to try to put them in order is not even wood working, but without using special corner fittings, Conductors, coasters and other inventions. He presented themselves in the workers' field and started sharpening my recommended way.
What I am going to use
I needed to experiment screwdriver and a strip of sandpaper. Fit and a drill, it should only work at very low speeds. A nazhdachku better take on fabric-based, because paper crumble quickly. Grain nazhdachki medium size. Thought 80-ka It will be the time, but you can try and another.
Cut from a sheet of sandpaper, a narrow strip where the 5-10 cm and that did not go to -syuda, shot her to the wooden rail. And I took dull drill bit 10 mm and before sharpening checked for clarity, how bad is it with him (this point is shown in the video below).
sharpening went
Sharpening insert the bit into the screwdriver and malooborotisty I turn it into reverse. Then sequentially attached to the drill nazhdachku rail. Just doing it to 20 holes and all! After this protsedurki drill should erode.
Upon completion of surfing screwdriver to normal operation and on the same side of the rail trying to drill a couple of holes.
On the size of the chip it is clear that the drill does not crawl on wood, both at the beginning and full of fiber cuts. The speed of the truth in a small screwdriver, but if you rearrange to drill, then I think everything will be fine.
ATTENTION! And here a link to a very professional and informative because the Zen-channel my brother - railwayman
Yes, and the quality of the holes can be seen that after a simple drill sharpening very adequately cope with the task. Special adapt certainly would provide an even better result, but at the right time is not always available, so take a way for service and advise you to try out in private practice.
