MAG-123A 120° flat surface grinding air micro grinder
KINSHUN MAG-123A / Air Micro Grinder (120° Flat Grinding Type)
Silent・High Torque / Taiwan-made Precision Gears / OEM・ODM Support
The MAG-123A is an air micro grinder optimized for flat grinding operations at 120° (45°). Its angled design reduces wrist strain, minimizing fatigue even during long working hours. With the adoption of precision gears, it produces low gear noise while achieving high precision and high torque. It features a low vibration and long lifespan design. Key components are consistently processed using in-house Japanese-made STAR (Automatic Lathe) multi-processing machines, ensuring the accuracy of parts and assembly. It is also capable of OEM/ODM (custom specifications, logos, packaging).

Applications/Examples of results
The MAG-123A (120° (45°) flat grinding dedicated type) is used for flat grinding, chamfering, deburring, and finishing of molds, jigs, and precision parts. Its 120° angle design reduces wrist strain and allows for easy operation without compromising posture even in recessed surfaces and narrow working areas. The precision gears produce minimal gear noise and provide a stable grinding feel with high torque, contributing to reduced variability in finishing quality. The 30mm interchangeable pad makes it easy to replace consumables, leading to reduced setup time on-site.
