Star-M STM8010 10 mm x 457 mm 8L Series Hardwood Auger Drill Bit

The Star-M 8L Series is a range of thirteen long ship auger bits for hardwood, from 10 mm to 32 mm in diameter. Every size is 457 mm overall (manufacturer-stated).

The supplier describes the 8L as a long ship auger with a 381 mm twist length, suited to hardwood applications (manufacturer-stated). It is the long-reach option in the Star-M hardwood range; the diameters sit on the same 457 mm body, so the choice is by hole size alone.

Common specifications

Key specifications

Overall length is on every supplier page for this series; the 381 mm twist length is shown on the supplier pages for nine of the thirteen sizes and is applied to the series (manufacturer-stated). Imperial sizes are the equivalents of the metric diameters.

Selecting the right option

Choose by hole diameter. All thirteen sizes share the same 457 mm length, so there is no length trade-off to weigh within this range. If you only need to reach about 305 mm, the 8M Series medium-length hardwood auger drill bits have a shorter body in the same diameters. The 12 mm and 13 mm sizes are also sold together as the 8L Series 12 mm and 13 mm hardwood auger bundle.
