LD-210 Golden Titanium Coated Wood Countersink Drill Bit Set | Wholesale Supplier

The LD-210 Golden Titanium Coated Wood Countersink Drill Bit Set is a specialized woodworking drill set designed to create clean, professional-looking screw installations in wood by combining pilot hole drilling and countersinking in a single operation. Each bit features a high-speed steel pilot drill at the tip that creates the proper size hole for the screw shank, while the countersink body above it widens the top of the hole to accommodate the screw head, allowing it to sit flush or below the wood surface for a clean finished appearance. The golden titanium nitride coating not only gives the bits a distinctive professional appearance but also reduces friction and heat buildup during drilling, extending bit life and producing cleaner holes with less burning or tear-out on the wood surface. The hexagonal shank fits standard 1/4 inch quick-change chucks found on most cordless and corded drills, providing secure grip without slipping under torque. The set includes multiple countersink sizes to match different screw diameters, from small 3mm bits for finishing screws to larger 10mm bits for deck screws and heavy-duty fasteners. A depth stop collar allows consistent countersink depth adjustment, ensuring every screw head sits at exactly the same depth across the entire project. The bits come organized in a durable plastic storage case with foam insert that protects the cutting edges and keeps the set organized between uses. Whether assembling flat-pack furniture, installing kitchen cabinets, building decks and fences, installing door and window hardware, doing woodworking joinery, or tackling DIY home improvement projects, the LD-210 countersink drill set delivers professional-quality screw installations with clean, flush results every time.
