Review on 🔩 Advanced Woodworking Smart Bit BDA140: Pre-Drilling & Countersinking Solution by Dino Burks

I've been using this drill bit for a week now while building a series of decks. It came with a bucket of screws from the TimberTech Reliaboard. This is the best countersink I have ever used and I have been using them for years. Ideal for wood or polymer. Widely used (all screws MUST be pre-drilled) without sacrificing performance. The only downside is that the depth gauge doesn't account for steep turns or bottlenecks. Otherwise I love this beat. Highly recommended. jtp
