The Mafell 090250 Lewis Auger Bit is a heavy-duty, large-diameter drilling tool featuring a 30 mm diameter and an extended 650 mm total length. Specifically designed for use with high-capacity drilling stations such as the Mafell BST 650S, this bit excels at creating large, deep holes for heavy hardware, dowels, and services in massive timber and log construction.

The robust hexagonal shank provides exceptional torque transmission, while the precision-ground lead screw and wide Lewis flutes ensure smooth self-feeding action and rapid waste removal, minimizing heat build-up during demanding, deep-reach drilling cycles.

Features & Benefits

• Extended Reach & Diameter: 650 mm length and 30 mm diameter accommodate heavy timber construction and large hardware installations.
• High-Torque Hex Shank: Built to handle the heavy rotational loads required by large-caliber auger bits.
• Optimized Lewis Flutes: Ensures efficient evacuation of heavy wood chips to prevent clogging and binding at depth.
• Self-Feeding Lead Screw: Pulls the bit smoothly through dense structural wood with reduced operator effort.
