Fully satisfied with drill bit quality.. earlier, I used to struggle drilling holes in wall or tiled wall..with these bits, it's a breeze!

बहुत बढ़िया है लोहा लकड़ी सब में काम कर रहा है

Very good

Easier to change bits on the drill machine. But the quality isn't that good. I used the smallest drill size on concrete and had disappointing results. After the first hole the bit became blunt. The larger size is still good as of now. But I didn't realise that the quality will be so bad.

I just drill one hole in wall of brick and tip of the tool is broke and stuk in wall , totally waste of money, not worthy

Donot serve the purpose but some work can be done

Nice,durable

Good and useful
