NITTO KOHKI NO.16434 Tool-less Jetbroach Annular Cutter

NITTO KOHKI Holesaw Cutter NO.16434 - Easy tool-less cutter replacement
NITTO KOHKI Jetbroach Annular Cutter Model NO.16434, size 34 mm (cutting depth 35 mm) – an industrial-grade cutting tool manufactured and imported from Japan, 100% authentic. An essential tool for drilling thick metal and structural steel trusted by engineers and professional technicians, commonly known in the industry as a "Jetbroach" or "Annular Cutter." The operating mechanism of this cutter cuts only the metal around the outer perimeter of the hole, unlike conventional twist drill bits that must grind away the entire workpiece core. This allows the Jetbroach to penetrate steel quickly, accurately, and with dramatically reduced torque load on the magnetic drill. No time wasted on pilot holes—saving time and energy while significantly extending machine service life.
