Hutchins 6 Hook 6-hole 3/16 Offset Industrial Water Sander (7547)

The Hutchins 6″ Hook 6-hole 3/16″ Offset Industrial Water Sander (7547) is a high-performance pneumatic wet sander specifically engineered for rigorous industrial applications. This tool stands out due to its patented through-the-pad venturi-driven water delivery system, which continuously supplies water to the work surface. This innovative feature effectively cools the sanded area, lubricates the abrasive, and significantly suppresses dust, resulting in a cleaner environment, a superior finish, and an extended lifespan for sanding pads. Designed for professionals, the Hutchins 7547 provides an efficient solution for achieving high-quality surface preparation in demanding environments.

KEY FEATURES AND BENEFITS:Integrated Water Delivery System: Features a patented “through-the-pad” venturi-driven system that uses the sander’s airflow to draw water from an external source. This continuously wets the sanding surface, providing lubrication, cooling, and effective dust suppression.High-Speed Random Orbit Action: Utilizes a “SuperCharged” 3/16″ offset random-orbit action to achieve over 13,000 RPM. This combination ensures aggressive material removal while still producing a consistently high-quality, swirl-free finish.Corrosion-Resistant Construction: The motor housing is zinc-coated, offering enhanced resistance to corrosion. This design consideration is critical for tools exposed to water, contributing to a longer service life and sustained performance.Reduced Operator Fatigue: Weighing only 2 lbs 4 oz and engineered for low vibration, this sander promotes comfortable operation during extended periods of use. The relatively low noise level of 80 dBa further contributes to a more pleasant working environment.Efficient Pad Management: Includes a patented built-in pad release mechanism, making it simple and quick to change sanding pads, thereby improving workflow efficiency.SPECIFICATIONS:Model Number: 7547Product Type: Random Orbit Wet SanderPad Size: 6 inchesOrbit Diameter (Offset): 3/16 inchesSpeed: 13,000+ RPMAir Consumption: 11.0 CFM at 90 PSIOperating Noise Level: 80 dBaWeight: 2 lbs 4 ozPad Type: Hookit (Hook and Loop)HOW TO USE:Prepare Water Source: Place the end of the included 20-foot water hose, fitted with a filter, into a clean water container. For optimal performance, consider adding 2–3 drops of liquid detergent to the water; this acts as a lubricant and aids in washing away sanding debris.Connect Air Supply: Connect your air supply hose to the sander’s air inlet. Ensure your air compressor is set to 90 PSI and that your air line has proper water traps and dryers to prevent moisture from entering the tool.Attach Sanding Pad: Secure a 6″ Hookit (hook and loop) non-hole water-based or film-backed sandpaper pad to the sander. Sandpaper without pre-punched holes is recommended for continuous water flow.Adjust Water Flow: With the sander running, turn the brass thumb screw on the tool counter-clockwise to fully open the water flow. Then, slowly turn it clockwise until the desired water flow is achieved. Adjust as needed to prevent hydroplaning or the pad from sticking due to insufficient water.Begin Sanding: Apply the sander to the surface to be worked on. Maintain even pressure and move the tool in overlapping patterns to ensure uniform material removal and a consistent finish.Post-Use Lubrication: After completing your sanding task, turn off the water flow and disconnect the air supply. Add 3–4 drops of pneumatic tool oil into the air inlet. Briefly depress the trigger for about two seconds to distribute the oil and lubricate the motor, which helps prevent internal rust.Storage: For periods of inactivity, remove the sanding pad and spray a small amount of lubricating oil (such as WD40) around the motor assembly to further protect against rust formation.BENEFITS OF USING HUTCHINS 6″ HOOK 6-HOLE 3/16″ OFFSET INDUSTRIAL WATER SANDER (7547):Achieves a very smooth, high-quality finish, particularly on clear coats and sensitive surfaces.Significantly reduces airborne dust particles, leading to a cleaner and safer working environment.Extends the lifespan of sanding pads and abrasives by keeping them cool and lubricated.Prevents heat buildup on the work surface, minimizing the risk of warping or burning materials.Facilitates faster material removal due to optimized abrasive performance and reduced friction.Ideal for preparing surfaces for painting, clear coating, or polishing in automotive, marine, and metalworking industries.Minimizes the need for extensive post-sanding cleanup, saving time and effort.Provides consistent and controlled water delivery for uniform results across large areas.FEATURES:Patented Water Feed System: Precision-engineered venturi system continuously wets the sanding surface.Efficient Random Orbit: Balanced 3/16″ orbit for aggressive yet smooth material removal.Water-Resistant Design: Zinc-coated motor housing ensures long-lasting performance in wet conditions.Low Vibration: Designed for comfortable, extended use without excessive operator fatigue.Quick Pad Change: Built-in pad release simplifies sanding pad replacement.Lightweight Build: Minimizes strain during prolonged use while maintaining control.Hookit Pad Compatibility: Secure 6-hole attachment system for reliable abrasive performance.Optimized for Wet Abrasives: Ideal for non-hole, water-based, or film-backed sanding pads.Made in the USA: Manufactured with American craftsmanship and components.
