Star-M is a Japanese brand legendary among woodworkers for their precision and "clean-cut"
The "Stubby" Advantage: At roughly half the length of a standard auger bit, it’s designed for use with impact drivers or cordless drills in cramped quarters (like between joists or inside cabinetry).
Single Spur Design: Unlike some bits that tear through wood, the 7S uses a single-spur cutting edge. This scores the outside circle of the hole first, resulting in an incredibly clean entry and exit with minimal "blowout."
Screw Point Tip: The lead screw pulls the bit into the wood effortlessly. You don’t need to lean on the drill; the bit does the work for you.
Teflon/Fluoro Coating: Most 7S bits feature a black coating that reduces friction and prevents resin buildup, which is crucial when boring 25mm holes that generate a lot of heat.
