The Hutchins 3/16" Random Orbital Sander 6" Pad (8660) is a professional-grade pneumatic tool engineered for superior surface preparation in automotive, woodworking, and industrial applications. Designed and manufactured in the USA by Hutchins Manufacturing Company, this sander is part of their renowned "Super Sander II" series, known for its performance and reliability. The 8660 model utilizes a unique random orbital action combined with a 3/16-inch offset, allowing for efficient material removal while consistently producing a smooth, swirl-free finish. This makes it an ideal choice for tasks ranging from aggressive shaping of body fillers and putties to precise feather-edging and preparing surfaces for painting or clear coating. Its robust construction ensures extended operational life, even under demanding professional use. The ergonomic design prioritizes user comfort, minimizing vibration and fatigue during prolonged periods of operation. Furthermore, the sander offers versatile dust management options, including vacuum compatibility and the ability to use a detachable dust bag, ensuring a cleaner work environment and improved visibility. The Hutchins 8660 embodies precision engineering, offering consistent power and a balanced operation that professionals rely on for achieving impeccable results. KEY FEATURES AND BENEFITS: Random Orbital Action (3/16" Orbit): Provides an aggressive yet swirl-free finish, making it suitable for both rapid material removal and fine finishing. This action prevents repetitive scratch patterns. 6-Inch Hook-Face Pad: Allows for quick and secure attachment of various abrasives, enhancing versatility and efficiency. The large pad covers more surface area per pass. Pneumatic Operation: Relies on compressed air, offering consistent power and lighter weight compared to electric models, reducing operator fatigue during extended use. High RPM Performance: Operates at 10,000+ RPM, ensuring fast material removal and efficient surface preparation for reduced work times. Optimized Air Consumption: Engineered for efficient use of air, contributing to lower operating costs and suitability for various shop air systems. Ergonomic Design: Features a balanced and comfortable grip, reducing vibration transfer to the operator for improved control and reduced fatigue during prolonged operations. Versatile Dust Management: Supports both vacuum systems for a virtually dust-free environment and allows for attachment of a dust collection bag where vacuum systems are not available. American Made Quality: Manufactured in the USA, ensuring high standards of craftsmanship, component quality, and reliability for professional users. SPECIFICATIONS: Model Number: 8660 Orbit Diameter: 3/16 inches Pad Size: 6 inches Pad Type: Hook-face (Hook & Loop) RPM: 10,000+ Air Consumption: 9.4 CFM at 90 PSI Weight: 4 lbs. 10 oz. Noise Level: 82 dBA Includes: Hutchins 8660 3/16" Random Orbital Sander 6" Pad HOW TO USE: Prepare Work Area: Ensure your workspace is clean, well-ventilated, and free of obstructions. Wear appropriate personal protective equipment (PPE) including safety glasses, hearing protection, and a dust mask. Connect Air Supply: Attach the sander's air inlet to a filtered, lubricated compressed air line. Ensure your air compressor can supply the required CFM and PSI for optimal performance. Attach Abrasive Pad: Select the appropriate grit abrasive disc for your task. Align the holes on the abrasive disc with the holes on the 6-inch hook-face pad and firmly press it into place to secure it. Optional Dust Collection: If using a vacuum system, connect the sander's dust port to your vacuum hose. If using a dust bag, attach it securely to the designated port. Begin Sanding: Hold the sander firmly with both hands, if applicable, and place the pad flat onto the surface to be sanded. Engage the trigger or lever to start the motor. Apply Even Pressure: Move the sander in overlapping passes, applying light, even pressure. Allow the tool's weight and random orbital action to do the work. Avoid pressing down too hard, as this can reduce effectiveness and potentially damage the surface. Monitor Progress: Periodically lift the sander to inspect the sanded area. Change abrasive discs as they become worn or clogged to maintain efficiency. Clean Up: Once sanding is complete, disconnect the air supply, remove the abrasive disc, and clean any dust or debris from the sander and work area. Store the sander in a clean, dry place. BENEFITS OF USING HUTCHINS 3/16" RANDOM ORBITAL SANDER 6" PAD (8660): Exceptional Finish Quality: The 3/16" random orbital action significantly reduces the risk of swirl marks, resulting in a consistently smooth and professional finish, crucial for painting and clear coat applications. Increased Productivity: Its high RPM and aggressive orbit enable quicker material removal and faster completion of sanding tasks compared to less powerful or smaller orbital sanders. Operator Comfort: The lightweight and balanced design, coupled with effective vibration dampening, allows for extended periods of use without causing significant hand or arm fatigue. Versatile Application: Effectively handles a wide range of tasks from heavy stock removal on fillers to fine finishing on delicate surfaces, adapting to various stages of surface preparation. Reduced Rework: The consistent and even sanding pattern minimizes the need for re-sanding or correction, saving time and abrasive costs. Longevity: Built with quality components and American manufacturing standards, ensuring a long operational life and reliability in demanding shop environments. Cleaner Workspace: Efficient dust collection capabilities, whether via vacuum system or dust bag, contribute to a healthier work environment and better visibility of the work surface. FEATURES: Robust dual-piston motor for balanced operation. Oversized 2-5/8" drive head for full contact sanding. Integrated 4-bearing shaft support system. Exhaust air direction away from the operator. Hook-face pad for quick abrasive changes. Low profile design for improved control. Engineered for smooth, low-vibration performance. Compatible with standard shop air systems. Designed for continuous professional use.
