NITTO KOHKI Jetbroach Annular Cutter 24.5 mm NO.16387 One-Touch Type

NITTO KOHKI Hole Cutter NO.16387 Size 24.5 mm Quick-Change Type
The NITTO KOHKI Jetbroach (Annular Cutter) model NO.16387 with a 24.5 mm cutting diameter and 35 mm depth is a premium industrial heavy plate cutting tool from Japan, engineered to elevate drilling speed and efficiency for structural steel and heavy engineering applications. Replacing conventional twist drills with annular cutting technology, it cuts only the periphery of the hole and ejects the center as a solid slug. This minimizes friction and heat buildup, allowing magnetic base drills to operate at full power with reduced motor strain, saving energy and cutting drilling time by up to 3 times compared to standard twist drills. The resulting holes are highly accurate, cleanly round, smooth, and burr-free, enabling immediate assembly without deburring. Most importantly, no pilot hole is required, maximizing productivity on every industrial job site.
