NITTO KOHKI Jetbroach Annular Cutter NO.16338 One-Touch Shank

The Jet Broach cutting process cuts only the peripheral rim of the hole (Annular Cutting), unlike conventional straight-shank or taper-shank twist drills that grind away the entire hole volume. This requires less torque, dissipates heat buildup effectively, and penetrates quickly. The cutting teeth are tipped with special-grade TCT (Tungsten Carbide Tipped) inserts with progressive cutting angles, enabling smooth, quiet drilling and outstandingly reducing cutter chipping—delivering clean, precise results meeting engineering standards.

One-Touch Locking System for Cutter Changes in Seconds: The quick-connect One-Touch sleeve enables rapid, securely locked, and highly safe installation onto magnetic base drills without needing a wrench.

High-Grade TCT Carbide Teeth Effortlessly Cut Thick Steel: Selected heat- and wear-resistant Tungsten Carbide tipped teeth allow fast and continuous drilling through thick structural steel.

Hollow Core Drilling Technology Reduces Machine Load: Cutting only the periphery of the hole reduces cutting resistance by half, allowing the drill press to cycle smoothly without motor overload.

Spiral Chip Flutes for Excellent Chip Evacuation: Mechanically designed side flutes smoothly evacuate metal swarf, minimizing jamming and friction buildup inside the hole.

Automatic Center Slug Ejection: Once breakthrough is achieved, the cutter works with the pilot pin to instantly eject the center slug, preventing it from sticking inside the bore.

Ideal for drilling thick steel plates in heavy structural steel fabrication, bridge construction, and factory roof trusses.

Used for drilling holes in structural steel beams (H-Beam / I-Beam / Channels) in building construction and railway station structures.

Specifically intended for use with mild steel, general structural steel (SS400), and high-tensile carbon steel.

Supports a 38 mm hole diameter with a maximum steel plate thickness or drilling depth of up to 25 mm
