Holzbearbeitungs-rotationsfeile, 7-teiliges Trapezbohrer-set

This tool kit is a comprehensive set designed specifically for woodworking drilling, grooving, positioning, and other multi-tasking operations. Made of high-speed steel, it features a standardized triangular handle design suitable for mainstream power tools such as hand drills and impact drills. The cutting edge employs a spiral groove design with a smooth chip removal channel, allowing for rapid sawdust removal and preventing sawdust blockage during drilling, which can lead to sawdust sticking or wood cracking. Reinforcing ribs at the connection between the handle and the saw teeth enhance torque resistance and prevent tool deformation during grooving. The kit is configured according to the woodworking process of "positioning → drilling → grooving" and includes components of various sizes.
