KINSHUN MAG-093A 90° Right Angle Micro Air Grinder – 23,500 RPM Surface Polishing Die Grinder with 30mm Backing Pad

The KINSHUN MAG-093A is a premium-grade pneumatic micro right-angle grinder meticulously designed for precision surface blending, flat grinding, and die-mold polishing in tight operational envelopes. As clearly outlined on the tool body in kinshun elbow MAG-093A macchina.png, this model boasts a perpendicular 90-degree head configuration, which provides direct downward leverage and uniform contact pressure, making it exceptionally reliable for cleaning up corners, vertical walls, and flat faces.
Equipped with a sturdy 30mm rubberized backing pad rather than a collet chuck, the MAG-093A is tailor-made to run self-adhesive round sanding discs and cup-type miniature grinding wheels. This broad-surface arrangement distributes the grinding forces evenly, mitigating structural chatter and preventing edge round-off on high-tolerance metalwork.
Operating at a stabilized free speed of 23,500 RPM, the air motor yields high torque delivery paired with controlled cutting speeds, protecting delicate substrates or specialty alloys from heat deformation. Internally, the tool utilizes KINSHUN’s standard-setting engineering: a high-precision gear assembly, a rugged alloy cylinder, and industrial-grade bearings that guarantee smooth rotation and minimize hand-arm vibration during extended shifts.

Key Features:

• 90° Right Angle Layout: Classic elbow head engineering for direct surface contact, maximizing tactical leverage and structural accuracy.
• 30mm Integrated Backing Pad: Ideal for securing self-adhesive sandpaper discs and miniature cup wheels for seamless flat-surface finishing.
• Optimized Speed Curve (23,500 RPM): Tailored speed profile that retains high torque while eliminating excessive friction heat on sensitive materials.
• Rear Exhaust Muffler Assembly: Channels cold air streams and mechanical oil mist safely backward away from the workpiece for a quieter and cleaner shop environment.
