The Techno AT3170K Micro Air Die Grinder Kit is a compact, high-speed pneumatic precision grinding tool designed for detailed grinding, polishing, deburring, engraving and finishing operations. The tool uses a 3mm (1/8-inch) collet and delivers an exceptionally high 54,000 RPM free speed, making it particularly suitable for precision work where a small abrasive or rotary accessory needs to operate at high speed. Techno's current price list identifies the AT3170K as a round-housing grinder kit with 54,000 RPM.

The AT3170K is powered by compressed air and uses a 1/4-inch PT air inlet with a 3/8-inch ID air hose. Published specifications specify a 90 PSI (6.3 bar) working pressure. The Techno specification also lists 5.7 SCFM average air consumption for the kit.

Its compact round-housing design makes it comfortable to hold like a pen during precision operations. The 3mm collet capacity allows the use of compatible small-diameter grinding, polishing and rotary accessories, making the tool useful for intricate work on metal and other suitable materials.
