The Gison GP-840SY is the premium choice for New Zealand professionals who value time. By replacing the traditional keyed chuck with a high-grip Jacobs keyless system, this 3/8" reversible air drill allows for instantaneous bit changes without searching for a chuck key.

Designed for High-Torque Precision

Running at a balanced 1,800 RPM, the GP-840SY provides the torque necessary for drilling into steel, stainless, and aluminium while maintaining the speed needed for timber and plastics. Its reversible motor makes it an excellent tool for tapping operations and backing out fasteners.

Key Features for the NZ Tradesman:

• Quick-Change Chuck: A durable 10mm keyless chuck that holds bits securely under high load.
• Ergonomic Pistol Grip: Balanced weight distribution (1.10kg) to reduce operator fatigue during repetitive assembly.
• One-Hand Reversibility: Easy-to-reach thumb lever for seamless transition between forward and reverse.
• Feathering Trigger: Provides granular control over drilling speed, essential for starting holes accurately on polished surfaces.
