This sander is engineered to efficiently remove minor imperfections, blend surfaces, and prepare materials for a high-quality final appearance, significantly enhancing the efficiency and quality of your finishing processes.

KEY FEATURES AND BENEFITS:Precise Random-Orbit Action: The random orbital motion ensures that sanding patterns are non-directional, effectively minimizing visible swirl marks and providing a consistently smooth surface finish, crucial for high-gloss applications.Fine 3/32″ Offset Orbit: This very small orbit diameter allows for extremely fine and controlled material removal, making it perfect for delicate tasks such as denibbing paint, spot repairs, and fine-grit sanding without aggressive material reduction.Dual Pad Versatility (1.25″ & 3″): The inclusion of two distinct hook-and-loop pad sizes (1 1/4″ and 2 7/8″) provides the flexibility to address a wide range of spot-specific imperfections, from very small blemishes to slightly larger areas, all with a single tool.Quick Change Pad Release: A patented design allows for rapid and tool-free interchangeability of the sanding pads. This feature saves significant time during projects, enabling quick adaptation to different task requirements without interruption.Variable Speed Control: The ability to adjust the RPM allows for precise control over the sanding intensity. This is particularly beneficial for delicate work requiring very low speeds to prevent over-sanding or damage, enhancing user control over the finish.Lightweight and Ergonomic Design: Weighing under 2 lbs, the sander is engineered for comfortable handling during prolonged use, reducing user fatigue and improving maneuverability in confined or awkward spaces.SPECIFICATIONS:Model Number: 3501Pad Sizes: 1 1/4″ and 2 7/8″ (Hook-and-Loop)Orbit Diameter (Offset): 3/32″RPM: 10,000+Weight: 1 lbs. 11.3 oz.Air Consumption: 11.0 CFM @ 90 PSINoise Level: 80 dBaAction: Random OrbitalIncluded in the box when purchased: Hutchins 3501 Finishing Sander, 1 1/4″ Hook-and-Loop Pad, 2 7/8″ Hook-and-Loop PadHOW TO USE:Prepare the Surface: Ensure the surface to be sanded is clean and free of large debris. For automotive paint, identify the specific nibs, dust specs, or imperfections requiring attention.Select the Correct Pad: Choose either the 1 1/4″ pad for very small, pinpoint imperfections or the 2 7/8″ pad for slightly larger blemishes or blending areas. Secure the appropriate hook-and-loop sanding disc to the selected pad.Connect to Air Supply: Attach the sander to a regulated air compressor line, ensuring the air pressure is set to 90 PSI for optimal performance.Begin Sanding: Hold the sander flat against the imperfection. Apply minimal, even pressure and start the tool. Move the sander in small, overlapping circles or back-and-forth motions over the target area. For denibbing, focus on the specific raised point.Monitor Progress: Frequently lift the sander to check the progress. The goal is to level the imperfection without affecting the surrounding clear coat or material excessively.Switch Pads (If Needed): If transitioning from a smaller imperfection to a larger blending area, utilize the quick-change pad release to switch to the larger pad and a finer grit abrasive if necessary.Clean and Polish: Once the imperfection is level and the desired finish is achieved, clean the sanded area thoroughly. Follow up with polishing compounds and a buffer to restore gloss, if applicable.BENEFITS OF USING HUTCHINS 3″ HOOK 3/32″ OFFSET FINISHING SANDER (3501):Achieves mirror-like finishes on painted surfaces and fine woodworking projects.Minimizes the need for extensive compounding and polishing post-sanding.Provides a professional appearance for high-quality repair and restoration work.Reduces overall project time due to efficient and precise material removal.Extends the life of abrasive discs by optimizing contact and reducing heat buildup.Enhances user comfort and reduces strain during detailed work sessions.FEATURES:Ergonomic composite housing: For user comfort.Built-in muffler: For reduced operating noise.Precision-machined internal components: For extended tool life.Integrated air regulator: For consistent performance.Patented quick-change hook-and-loop pad system: For fast pad replacement.Orbital action: Specifically designed for swirl-free finishing.
