Great price. ### ⭐⭐⭐⭐⭐ Good drill *by on Reviewed in the United States 1 March 2021* This worked perfect. I needed to cut the stone for my shower floor. I clamped the tile sheet in a drill press and drilled it. Came out perfect. Ran it dry and it had no problem. Still plenty of cutting left if I ever need it again. For the price this was totally worth it. ### ⭐⭐⭐⭐⭐ Job completed with normal drill. *by on Reviewed in Singapore 5 September 2025* got the job done. 2 holes. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/400316789-2-inch-50mm-diamond-drill-bits-diamond-hole-saw-hollow](https://www.desertcart.kr/products/400316789-2-inch-50mm-diamond-drill-bits-diamond-hole-saw-hollow) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-09-19*
