FAMAG 1493 Profi auger bits are engineered for deep-hole drilling in European and tropical hardwoods, including dense species like Bongossi. Their Lewis-pattern geometry ensures self-feeding entry, precise alignment, and efficient chip evacuation for burr-free holes. Set of 6 Augers in a wooden case.

📏 Set Contents

• Augers included: 10mm, 12mm, 14mm, 16mm, 18mm and 20mm diameters

• Overall Length: 460 mm total, 380 mm flute length.

• Shank Length: 60 mm hex profile for secure mounting.

🌲 Lewis-Pattern Design

• Brad Point & Underknife: Sharp spur incises fibres; underknife minimizes heat and prevents tear-out.

• Main Cutting Blade: Broad spiral channel clears chips rapidly, reducing clogging and friction.

• Thread Point: Self-feeds the bit into wood for consistent depth and zero drift.

🔩 Build & Shank Features

• Stepped Head Profile: Slim tip reduces resistance and heat buildup in deep holes.

• 60 mm Hexagonal Shank: Anti-twist design locks into 3-jaw chucks or joinery machines for slip-free operation.

• Alloyed Tool Steel: Premium material offers high strength, easy regrindability, and long service life.

⚙️ Speed & Usage Tips

• Recommended RPM: 500 – 2 800 rpm (e.g., Ø 12 mm at ~2 000 rpm in softwood; reduce speed for dense tropical hardwoods).

• Machine Compatibility: High-torque joinery machines and hand-held drills (≥ 50 Nm).

• Tip Replacement: HSS thread point and underknife are serviceable, extending bit lifespan and maintaining peak performance.

🌟 Applications & Advantages

• Hardwood Joinery: Ideal for mortises, dowel holes, stud-bolt drilling in oak, maple, Bongossi, and similar timbers.

• Deep-Hole Capability: 460 mm reach enables through-grain drilling without pre-bore.

• Clean Finish: Efficient chip evacuation and burr-free entry minimize sanding and rework.

• Durability: Low-heat geometry and alloyed steel resist wear under continuous use.
