It makes them hard and unsafe to use without some adaptation. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/92690659-woodwork-drill-bits-4pcs-wood-square-hole-mortising-chisel-drill](https://www.desertcart.lk/products/92690659-woodwork-drill-bits-4pcs-wood-square-hole-mortising-chisel-drill) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-06-27*
