Air Wet Polisher 4 Inch Variable Speed Pneumatic Tool for Marble and Granite with M14 Thread

Airpowered variablespeed wet polisher designed for stone fabrication and onsite wet polishing tasks. Operates without electricity when used wet and is engineered for lower noise at rotation speeds to improve working conditions. Key specifications Air consumption: 16 cfm (0.45 m3/min) Air pressure: 90 psi (621 kPa) Air inlet: 1/4 inch NPT Shaft thread: M14 and 5/8 inch11 Noload speed: 0 to 4500 rpm Pad diameter: 4 inch Why this tool matters Airpowered wet operation: Eliminates the need for electric power during wet polishing, reducing the risk of electrical hazards in wet environments and simplifying setup on job sites. Variable speed control: Allows precise adjustment of rotation speed from idle to 4500 rpm to match material and diamond pad requirements for consistent finishes. Quieter performance: Designed to reduce operational noise, especially at higher speeds, which helps maintain better communication and comfort in busy fabrication shops. Compact pad size and universal threads: The 4 inch pad and dualcompatible shaft threads make the tool suitable for common diamond pads and backing plates used in stone work. Performance and compatibility Works with standard 4 inch polishing pads and backing plates that fit M14 or 5/8 inch11 shaft threads. Requires a air supply delivering approximately 16 cfm at 90 psi through a 1/4 inch NPT inlet. Variable speed capability supports coarse grinding through fine polishing stages on natural and engineered stone. Practical applications Granite and marble countertop finishing: Use for shaping edges, leveling small areas, and achieving a polished finish in wet conditions without electrical power at the work surface. Stone fabrication shops: Ideal for localized polishing tasks, blending seams, and detail work where a compact, controllable wet polisher is required. Onsite repairs and restoration: Portable air operation and reduced noise make it suitable for work in occupied spaces where minimizing disruption is important. Operational notes Ensure adequate air supply and use proper hose and fittings sized for 16 cfm at 90 psi. Match pad and backing plate thread size to M14 or 5/8 inch11 shaft threads. Follow standard wet polishing practices for water flow and pad selection to achieve desired surface finish. This pneumatic wet polisher offers a practical, noisereduced option for stone professionals who need a compact, airdriven tool for wet polishing and finishing tasks.
