Industrial Efficiency: The Keyless Advantage

The Gison GP-836DY takes the proven power of the 836-series and adds a high-quality 1/2" (13mm) Jacobs keyless chuck. This allows tradespeople to switch between drill bits, reamers, and drivers in seconds without searching for a chuck key—saving significant time in high-volume production environments.

Performance Features

• Double Reduction Planetary Gears: Designed for "Extra Hard" work, providing the mechanical advantage needed to drill large 13mm holes without the motor stalling.
• One-Hand Reversible Action: The direction switch is perfectly positioned for thumb operation, allowing you to back out bits safely and quickly.
• Variable Speed Control: The sensitive trigger allows for a soft start, preventing bit wander and ensuring precision on polished surfaces.
• Standard Auxiliary Handle: Includes a heavy-duty side handle to manage the high torque levels safely.
