The Fein AGSZ 18-90 LBL AS N00 71230661000 is a professional 18V cordless long-neck die grinder designed for precision grinding, brushing, satin finishing and polishing applications. Its extended, narrow neck provides a large plunge depth, making it particularly useful for reaching recessed areas and performing grinding work inside pipes and other difficult-to-access workpieces.

Powered by a brushless FEIN PowerDrive motor, the grinder provides an electronically adjustable no-load speed of 2,900–9,000 RPM. This broad speed range allows the operator to select an appropriate speed for different abrasive materials, polishing accessories and workpiece requirements. It supports grinding wheels up to 50mm, polishing discs up to 80mm, collets up to 8mm and cutters up to 12mm.

The completely enclosed motor housing helps protect the motor against aggressive ceramic and mineral dust, supporting dependable performance in demanding workshop and industrial environments. The brushless motor provides the power and durability expected from a professional cordless tool.

FEIN's POWERtronic tacho electronics, electronic speed preselection, soft start, restart protection, blockage monitoring and electronic overload protection help provide controlled and reliable operation. The motor is decoupled from the housing and mounted separately with additional vibration dampers to support smooth, low-vibration working.

The long, narrow neck enables deep access into workpieces, while the integrated LED work light improves visibility around the working area. A replaceable rubber neck bearing cover provides additional protection around the long-neck assembly.

The tool operates on the 18V AMPShare battery platform, allowing compatibility with 18V AMPShare ProCORE batteries and chargers and suitable 18V Bosch Professional cordless devices. The standard package is supplied as a tool-only version, with battery and charger not included.
