Aluminum Gear Assembly — Replacement for BOSCH TWS6600 and GWS6100 Angle Grinders Key benefits Restores drive performance: replaces worn or damaged gears to recover smooth power transfer and consistent torque. Reduces vibration and tool strain: precision machining and correct fit minimize unwanted vibration and improve handling. Extends tool life: quality replacement parts reduce wear on other components and help prevent mechanical failure when maintained properly. Compatibility Specifically compatible with BOSCH TWS6600 and GWS6100 models (also referred to as BOSCH 6100 angle grinders). Manufactured to exact dimensional specifications (as shown in images) for direct installation and reliable fit. Material and construction Made from aluminum alloy for a lightweight, robust assembly. Good heat dissipation and structural integrity for regular powertool use. Durable construction designed to withstand the demands of cutting, grinding, and continuous operation. Performance and function Engineered for consistent performance and reliable power transfer between motor and grinding wheel. Precision dimensions reduce play in the drive train, lowering vibration and improving cutting/grinding accuracy. Lightweight design helps reduce operator fatigue during extended use without compromising durability. Why you need this part this gear assembly when you experience grinding inefficiency, increased vibration, or noisy operation. Using a matching, grade replacement keeps your grinder operating close to original specifications and avoids cascading wear on bearings and other components. Regular replacement as part of maintenance preserves cutting and grinding quality and reduces downtime. Typical applications Metal fabrication and welding shops: restore grinder responsiveness for beveling, weld cleaning, and surface preparation. Construction and masonry work: maintain consistent cutting performance on rebar, tile, and masonry materials. Automotive and maintenance: reliable wheel control for rust removal, paint stripping, and panel work. Installation notes Designed as a direct replacement; verify model compatibility (BOSCH TWS6600 or GWS6100) before installation. Refer to images for exact dimensional specifications and ensure correct alignment during fitting. Routine inspection and timely replacement will help maintain tool performance. Materials: aluminum alloy Compatible models: BOSCH TWS6600, GWS6100 (BOSCH 6100) Function: gear assembly for angle grinder drive train If your grinder shows worn gearing, increased vibration, or reduced cutting/grinding efficiency, this aluminum gear assembly provides a durable, precisely made replacement to restore performance and extend the working life of your tool.
