Drill flat bits r hardened and sharp to drill wood easily... Works well

The bits look really good, but they are far from it. First and foremost, the bits are not sharpened adequately, so you will need to sharpen them yourself. Second, the bit are not perfectly straight and as a result the drill vibrates like crazy. I sharpened the bits using a triangular file, and it was very easy to sharpen, which means the metal is probably mild steel ( or maybe not, a file can easily bite into the metal), and I use a hammer to straighten the bits. Now it can drill through soft wood easily, I wouldn't wanna use them for drilling through hard woods. is it worth Rs 330? I have no idea, but atleast it works fine after a few filing and hammering. Is it a good drill bit? Absolutely NO, but for the price I would say it's an ok bits, buy it if it's just for casual use, and I bet professionals wouldn't even bother taking a look.

avrage

Metal is not hard as expected.

Very badly finished tool. Cutting edges were not prepared properly. Had to return the tools. Such products will bring disrepute to Amazon.

Well made shank drill bits. For the smaller size like 10,12 and 16 mm I had no problem drilling the holes with not much effort. But anything above that may require a drill press to get a clean hole. It can be done with a handheld drill, but much effort is required and the holes are not always straight. However, its a product I can recommend without any hesitation.

Good and useful
