Nitto Kohki JEX-24 Needle Scaler

Nitto Kohki JEX-24 Pneumatic Jet Chisel Needle Scaler

The Nitto Kohki JEX-24 Jet Chisel is a premier, industrial-grade pneumatic needle scaler engineered for high-efficiency surface preparation, cleaning, and material removal. Operating at a blistering 4,000 blows per minute, this heavy-duty pistol-grip tool handles the most challenging industrial and maritime applications, stripping away stubborn coatings while contours adjust dynamically to uneven surfaces.

Key Features & Benefits

• Fully Springless Core Engineering: The only tool layout of its class constructed entirely without internal spring components—eliminating structural spring breaks, irregular force dropouts, and optimizing air optimization.
• Shot Peening Strengthening Effect: Delivers high-speed multi-needle kinetic impact that introduces beneficial compressive residual stress, significantly reinforcing and strengthening deteriorated structural weld components.
• Automatic Contour Self-Adjustment: High-alloy steel wire needles immediately slide independently to conform precisely around rivets, corners, structural profiles, and uneven casting depths.
• Aggressive Multi-Material Stripping: Powerfully strips away thick weld slag, oxidized rust layers, marine scale, heavy paint buildup, and encrusted concrete residue down to bare steel.
• Dual Needle Array Versatility: Ships ready for robust multi-surface processing using interchangeable standard 3mm needles or fine-detailed optional 2mm arrays.

Technical Specifications

Advanced Air System Mechanics

• Die-Cast Mechanical Integrity: High-durability alloy body casting isolates pneumatic recoil pulses from the user, reducing hand-arm vibration fatigue during extended descaling runs.
• Straight-Line Piston Stroke: Balanced inline kinetic design focuses force down through the needle guide assembly, resulting in continuous material removal speeds.
