Overview

The NSi Industries AL78 Auger Bit (SKU: AL78) is a heavy-duty twist flute auger bit designed for professional drilling in wood and other soft materials. This 7/8-inch diameter bit features an 18-inch overall length, providing deep reach for applications requiring precise, long-hole drilling. The 7/16-inch hex shank ensures secure engagement with compatible power tools, preventing slippage during operation. The twist flute design facilitates efficient chip removal, reducing friction and heat buildup while improving drilling speed and accuracy. Constructed from heat-treated steel, the AL78 is engineered to withstand demanding industrial environments, including construction, woodworking, and fabrication tasks. The bit includes a self-feeding screw point for smooth entry into materials and a hollow center for fast chip evacuation. Compatible with NSi Industries' auger bit extensions (sold separately), this bit can be extended for deeper drilling applications. For maintenance, the bit can be resharpened using a Cully™ auger bit sharpening file (Part #09382), extending its service life and reducing replacement costs. Ideal for professionals who require reliable, long-lasting drilling performance, the AL78 combines durability, precision, and versatility in a single tool.
