NITTO KOHKI Jetbroach Annular Cutter NO.16386 One-Touch Shank

NITTO KOHKI NO.16386 Hole Saw Cutter: Easy, Tool-Free Blade Replacement
The NITTO KOHKI NO.16386 Jetbroach (Annular Cutter), with a 23.5 mm drilling diameter and 35 mm cutting depth, is a premium metal and thick plate hole-cutting innovation imported directly from Japan. Designed to revolutionize speed and maximize efficiency for structural engineering, shipbuilding, and heavy metal fabrication jobsites, it replaces traditional drill bits that grind away the entire core. The NITTO KOHKI Jetbroach utilizes an annular cutting technique that cuts metal only around the circumference of the hole and ejects the center core as a solid slug. This method drastically reduces friction buildup and heat generation, allowing magnetic drill presses to operate at full power without overloading, saving energy, and cutting drilling time by up to 3 times compared to conventional twist drills. The resulting holes are highly precise, perfectly round, and feature an ultra-smooth, burr-free inner finish. Operators can proceed directly to assembly without wasting time deburring, and most importantly, no pilot hole is required—maximizing jobsite productivity.
