Gunpla 1/4-Inch Angle Air Die Grinder — 90° Heavy Duty Performance

Meet Gunpla’s compact 1/4-inch angle air die grinder, a power tool designed for precision work in tight spaces. Operating up to 20,000 RPM with a practical 90-degree head, it lets you reach challenging corners, shoulders, and hard-to-access edges with steady control. Built for durability, this grinder uses specially treated core components intended to withstand demanding use and maintain consistent performance over time.

Durability goes hand in hand with versatility. The unit ships with a robust accessory set that broadens its finishing capabilities. You’ll find multiple disc types and textures designed to tackle metal surface preparation, deburring, polishing, and oxidation removal across a range of materials and projects. In addition to the power head, the kit includes a generous supply of roll-lock discs so you can progress from material removal to a refined surface finish in fewer steps.

Real-life applications and experience
