NITTO KOHKI BHM03050 Drill Chuck Adapter for Air Tools

The holder is designed and manufactured from special-grade steel, fully hardened and precision ground for high durability against extreme torque encountered in heavy steel drilling. It features an integrated Coolant Feed system that delivers cutting fluid directly into the core of the cutter, effectively reducing heat buildup at the cutting tip. This results in smoother, faster drilling and significantly extends the service life of your JetBroach cutters.

High Precision & Rigidity: Manufactured with high precision (low run-out) to reduce vibration and wobble during drilling, ensuring smooth, accurately sized holes.

One-Touch System Support: Supports 3/4-inch One-Touch JetBroach cutters, allowing quick insertion and tool changes to boost productivity on the line.

Integrated Coolant System: Built-in coolant hose connection delivers fluid directly to the center of the cutter during operation, preventing tool burning and reducing wear.

Industrial Morse Taper 3: Standard MT3 (Morse Taper No. 3) shank fits tightly into the machine spindle, ensuring safety without slippage during heavy load applications.

Used for drilling large structural steel, beam drilling (H-Beam / I-Beam) in building and bridge structures

Automotive body assembly, truck assembly, shipbuilding, and heavy industries requiring mass drilling in thick steel

Ideal for machine shops and steel fabrication workshops requiring higher speed and precision than traditional taper shank drill bits
