Excellent product
Absolutely worth every rupee. Purchased in 2024, and even after two years of use (2026), this drill bit is still sharp and reliable. The durability is outstanding. If you want a long-lasting drill bit, don’t think twice just buy it.

Very Poor Quality Drill Bits – Not for Concrete Use
Absolutely terrible product—avoid at all costs. The drill bits are extremely soft and wear out after just a few uses. I couldn’t drill more than 4–5 holes in concrete before they became completely blunt. Not suitable for concrete or heavy-duty work. Total waste of money—do not recommend.
