The AKUMA® Trippelborrset is a precision 7-piece bit set designed to drill, tap, and countersink in a single smooth operation—saving time and increasing accuracy. Made from high-speed steel (HSS) with a TiN coating, each bit cuts clean threads and burr-free holes in materials like steel, aluminum, and plastics. The aggressive flute geometry ensures fast chip evacuation and consistent thread formation.

All bits are built with a universal 1/4″ hex shank, making them compatible with standard drills, impact drivers, and quick-change chucks. Whether in the workshop or on-site, this set eliminates the need to switch between multiple tools or bits. Perfect for maintenance technicians, metal fabricators, or DIY pros who need to get work done faster. From M3 to M10, you’ll be covered in just one case.
