NITTO KOHKI Jetbroach Annular Cutter No. 16420 One-Touch Shank

World-Class TCT (Tungsten Carbide Tipped) Cutters: The cutting teeth are made from extra-thick, special-grade carbide, resistant to heat accumulation and wear from high-speed metal friction. Capable of continuous, long-lasting drilling in ductile iron, cast iron, and thick stainless steel plates.
One-Touch (Round Shank) Single-Handed Quick-Change Locking System: The shank features a standard round profile with a One-Touch quick-release groove. It can be snapped directly into the chuck of a magnetic base drill using just one bare hand without needing a wrench. Provides a firm, tight grip with no slippage for maximum safety.
High-Efficiency Chip Ejection Flutes: The flutes around the cutter are calculated with precise angles to evacuate metal chips quickly, reducing heat accumulation and chip jamming inside—the main causes of cutter breakage.

Full drilling depth of 50 mm: The flute length is designed to penetrate extra-thick steel plates or layered metal plates completely in a single drilling pass.

Suitable for drilling bolt holes in thick steel plates for building construction projects, warehouses, and large steel structures.

Used in railway construction, maintenance, and track laying for drilling railway steel with high toughness and hardness.

Ideal for steelworkers in shipyards, heavy machinery manufacturing industries, and on-site maintenance requiring speed and clean, neat jobsite results.
