STIHL augerbits - 5.9" (150 mm) dia. - BT 130/131

STIHL Auger Bits are built and designed with durability in mind. Every bit design is tested, by STIHL, in a variety of soils across the country. Bit heads are cast from a single piece of heat-treated alloy for outstanding durability and drilling performance. The cutter heads are easy to remove and feature an offset tooth, instead of an installed plate, to improve drilling performance and avoid lockups. Bits also feature a dual flute pilot drill for accurate alignment and straight holes. It all adds up to quality that doesn't compromise  not one bit.
