NITTO KOHKI Jetbroach Annular Cutter No. 16419 One-Touch Shank 19 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.

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.
