The FAMAG WS 3510 Spade Bits are designed for quick, accurate pilot holes in softwoods. Its classic centering tip and dual pre‑cutters deliver superior guidance compared to standard bits. Featuring an E 6.3 mm hex shank and 150 mm overall length, it’s a handy accessory for every DIY woodworking project.

🛠️ One‑Piece WS Tool Steel Construction

Made from premium WS tool steel in a single‑piece design, the bit resists wear and maintains sharpness. The robust construction ensures consistent performance during repeated drilling.

🎯 Precision Centering Tip

The hardened centering tip guarantees exact hole starts, preventing bit “walk” and ensuring every pilot hole begins precisely where intended—no extra pilot drilling required.

⚙️ Dual Pre‑Cutters for Cleaner Results

Two ground scoring edges cut the wood fibers ahead of the main cutter, reducing tear‑out and producing cleaner hole walls than conventional flat center drills.

🌲 Optimized for Softwood Use

Specifically engineered for pine, spruce, fir, and similar softwood species, the WS 3510 excels at creating accurate, burr‑free pilot holes without the need for specialized equipment.

🚫 Not Recommended for Hardwood

While excellent in softwoods, flat center drills are not designed for the higher demands of hardwood. For oak, maple, or other dense timbers, consider FAMAG’s Bormax® WS/HM cylinder head drills.
