It came with the order. I used it to build the entire deck as it made screwing in the screws look much better. EXCELLENT countersink. The best I've used, and I do a lot of carpentry. Wife saw me use it on finish work promptly appropriated it. Figures. So I got her a brand new one for Christmas, and ordered myself a replacement as well as a pack of replacement drill bits. This is one of the best and most used bits in my tool box. LOVE IT. Very sharp and clean drilling. If you do a lot of deck work or finish work, you'll want one. --- ## 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.com.cy/products/6235161-starborn-bda141-no-8-trim-head-smart-bit-pre-drilling](https://www.desertcart.com.cy/products/6235161-starborn-bda141-no-8-trim-head-smart-bit-pre-drilling) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-08-22*
