NITTO KOHKI Hole Cutter NO.16383 Jetbroach 35L 20.5 mm
The NITTO KOHKI Jetbroach / Annular Cutter Model NO.16383, with a 20.5 mm hole diameter and 35 mm depth of cut (35L), is a premium-grade heavy metal plate drilling tool from Japan engineered to truly elevate speed and efficiency in structural steelwork, civil engineering, and heavy stainless steel applications. Its design employs annular cutting technology, which removes metal solely along the perimeter of the hole and ejects the solid core as a round steel slug. This advanced cutting method minimizes friction and heat buildup, enabling magnetic base drills to operate at full power without straining the motor, saving energy and reducing drilling time by up to 3 times compared to conventional high-speed twist drills. The finished holes deliver maximum accuracy, crisp round edges, and a smooth burr-free interior finish, allowing operators to move forward with assembly without spending time deburring—and eliminating the need for pilot holes, thus maximizing productivity on every job site.
