I'm improvising cement board for skirting on a manufactured home I'm working on. I looked high and low for a tool that would pre-drill and countersink as I want it to look finished once the #10 gray poly screws are sunk. I can't imagine why it wouldn't work but it is an expensive bit $$$ Good Luck **Q: What size and type of screw did you use to secure the Hardiboard after using this tool?** A: This product is a bit expensive, but does an excellent job. In my case I used 3/16 inch Tapcons to secure half inch Hardi-board. The countersink was a bit more than 1/16 inch below the surface. I had no problems with any of the Tapcons pulling through the countersink hole. Makes a nice clean insulation that can even be used in place of wallboard for a weeping cinder block wall. Will also work with 1/4 inch hardi-board but wouldn't recommend it unless you use the 1/4 inch sized tapcons. ## Frequently Bought Together - Smart-Bit Pre-drilling and Countersinking Tool for Fiber Cement Board Including James Hardie Fiber Cement Board - DEWALT 4-1/2IN 4T PCD SAW BLADE - Diablo HardieBlade Saw Blade for Fiber Cement - 7-1/4" x 4-Teeth, PCD Tipped - D0704DH --- ## 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.at/products/542622976-smart-bit-pre-drilling-and-countersinking-tool-for-fiber-cement](https://www.desertcart.at/products/542622976-smart-bit-pre-drilling-and-countersinking-tool-for-fiber-cement) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-04-23*
