Power Where It Counts: 67mm Piston Stroke

The Gison GP-190 is engineered for tradespeople who need more than just vibration—they need impact. With a significantly longer 67mm stroke than standard air hammers, the GP-190 delivers massive kinetic energy at 3,200 BPM. This makes it the ideal choice for heavy-duty automotive, construction, and marine applications across New Zealand.

Why Professionals Choose the GP-190

• Maximum Penetration: The long stroke allows for deeper cutting and more effective bolt shearing than high-speed, short-stroke models.
• Standard 10mm Shank: Compatible with all standard 0.401" round-shank chisels and accessories.
• Rugged Build Quality: Heat-treated cylinder and piston ensure longevity in harsh NZ workshop environments.
• Precise Trigger Control: Featherable trigger allows for delicate starts before applying full impact power.
