NITTO KOHKI Jetbroach Annular Cutter 22 mm NO.16322

NITTO KOHKI Steel Annular Cutter NO.16322 Size 22 mm Jetbroach Series
Jetbroach (Annular Cutter) W.W. Grainger, Inc. presents a proprietary high-performance cutting tool from Japan: NITTO KOHKI Model NO.16322, 22 mm hole diameter, 35 mm depth. A heavy-duty industrial-grade thick sheet metal coring tool that transforms structural steel drilling and metal engineering to be faster, more precise, and exceptionally safe. With innovative annular cutting technique, the cutter cuts only the circumference of the hole and ejects the center steel core as a solid cylindrical slug—unlike conventional twist drills that must pulverize the entire volume of metal. This technology significantly reduces friction and heat build-up, allowing magnetic drill presses to operate at full power without overloading, cutting drilling time by more than 3 times. It delivers smooth, clean, burr-free hole surfaces so workers can proceed immediately without deburring, and eliminates the need for pilot holes, greatly enhancing on-site and factory productivity.
