We have been producing drill bits, hole saws and chisels for more than 26 years till now. As to drill bits, we only adopt original carbide tip YG8C, not recycle one. And it is much strong. Besides, 40CR is much better than normal material 45# steel. For example, 6X160mm, we can drill more than 150 holes.
