Nitto Kohki Jetbroach Carbide Annular Cutters
The Nitto Kohki Jetbroach series delivers faster, cleaner, and more efficient hole-cutting than conventional twist drills. Designed with tungsten carbide tips and Nitto’s exclusive one-touch replacement system, these cutters are engineered for productivity, precision, and long tool life.
Key Benefits
- One-Touch Mounting System – Change cutters quickly without tools, saving valuable time on the job.
- Faster Cutting Performance – Carbide tips deliver superior speed and durability in steel, stainless, and other hard materials.
- Low Cutting Resistance – Annular cutting design removes only the material at the edge, reducing load on the drill and operator.
- No Pilot Hole Needed – Single-pass drilling means fewer steps and less downtime.
- Versatile Applications – Capable of cutting slanted, elongated, or edge holes with precision.
- Cleaner Work Area – Produces fewer chips and minimal slag for easier cleanup.
- Long Service Life – Self-centering arbor design improves concentricity, reduces vibration, and extends cutter life.
Technical Features
- Available diameters: 9/16″ – 4″ (fractional and metric sizes available).
- Compatible with current and previous Atra Ace models (using hex socket set screw).
- Designed for mag drills and fabrication shops needing speed and accuracy.
- Ideal for steel fabricators, construction, shipbuilding, and installation contractors.
Why Jetbroach Over Twist Drills?
- No dead point at the center → faster starts.
- Peripheral cutting reduces effort.
- Shorter drilling times and extended tool life.
