Milwaukee M18 Brushless 1/4" Hex Impact Driver (Model 3650-20)

This is a Milwaukee brand cordless 1/4-inch hex impact driver, identified as model 3650-20. The tool features the brand's signature high-visibility red and black overmold design, specifically engineered for ergonomic grip and durability. It is a compact power tool constructed with a cast metal gear housing finished in a matte gray, while the main body is composed of heavy-duty reinforced polymer. Notable markings include the classic 'Milwaukee' script in white atop the motor housing and the 'BRUSHLESS' designation embossed directly below it, signifying a high-efficiency motor with elongated lifespan compared to brushed models. The tool is equipped with a standard trigger switch and a forward/reverse sliding selector. The base is designed for the M18 battery platform and includes mounting points for a belt clip or bit holder, evidenced by the brass threaded insert at the bottom. In terms of condition, the tool shows moderate signs of professional use, characterized by surface scuffing on the red plastic housing and localized black staining/grease marks on the rubberized grip areas. There is visible wear on the bit chuck assembly and slight paint thinning on the metal gear case, consistent with regular operation in a construction environment. The tool appears structurally sound with no deep cracks or missing components, maintaining a patina of active trade use.

Based on my examination of the provided specifications and the Milwaukee Model 3650-20, I have assessed the tool's fair market value. This specific model is a 'Brushless' variant, which sits in Milwaukee’s mid-range tier—offering better efficiency than brushed models but positioned below the premium 'FUEL' (Powerstate) line. My visual inspection confirms the tool is authentic, displaying the correct overmold patterns, proprietary brass inserts, and legitimate branding consistent with Milwaukee’s manufacturing standards. The 'moderate use' condition, featuring scuffing and grease marks, indicates a tool that has seen active duty in a professional setting. While these cosmetic issues do not impact utility, they do depress the value compared to 'New-Old Stock' or light-duty home-use units. Market demand for the M18 platform remains exceptionally high; however, because this is a tool-only (bare tool) assessment without a battery, charger, or a FUEL-grade motor, rarity is non-existent. Comparables on secondary markets (eBay, local trade-ins) for used 3650-20 units typically range from $40 to $65 depending on regional demand. My valuation assumes the internal planetary gears and trigger electronics are fully functional. Limitations: This appraisal is based on visual evidence and reported condition. A physical inspection would be required to test the motor for bearing noise, verify the health of the 1/4" hex chuck's retention spring, and ensure no internal carbon buildup or overheating damage exists. For absolute authentication of internal components, I would require a serial number check against Milwaukee’s registry and a performance load test.
