NITTO KOHKI Jetbroach Annular Cutter No. 16418 One-Touch Shank 18 mm

Extra-thick TCT (Tungsten Carbide Tipped) cutting teeth: The cutting tips are tipped with high-grade carbide, resisting heat accumulation and wear from high-speed metal friction, ensuring smooth, continuous drilling in alloy and structural steels.
One-Touch quick-change shank locking system (Round Shank): The shank features an international standard round shank design for a one-touch quick-change mechanism. It can be snapped securely into the chuck of a magnetic base drill by hand immediately, offering a secure, tight, non-slip, and safe fit.
High-efficiency chip ejection flute: The flutes around the cutter body are precisely calculated to rapidly evacuate chips from the hole, reducing internal chip jamming—the main cause of cutter breakage.

50 mm cutting depth capacity: Supports drilling completely through extra-thick steel plates or multi-layered metal plates in a single plunge.
Applications

Ideal for drilling bolt holes in thick steel plates, building construction, warehouses, factories, or steel bridge fabrication.

Used in railway construction, maintenance, and railroad engineering for drilling extra-tough steel with high hardness.

Ideal for shipyard technicians, heavy machinery manufacturing industries, and on-site maintenance that demands speed and clean, tidy work.
