Description

6-Inch (150mm) M14 Polishing Sponge Set, 3-Piece with Threaded Backing Pads

Brief Overview

This 3-piece polishing sponge set delivers essential finishing capability for any shop equipped with pneumatic or electric polishers. Each 150mm (6-inch) foam pad features a securely threaded M14 brass insert, allowing quick connection via the included metal mandrel. The set includes three distinct foam densities—red, yellow, and black—enabling progression from pre-polishing through high-gloss finishing on a single setup. Pair this with expandable polishing pad options or a complete pneumatic polishing system to round out your finishing department.

Key Features

  • Three Polishing Densities: Red (aggressive), yellow (medium), and black (finishing) pads for versatile surface preparation and final gloss work
  • M14 Threaded Connection: Brass female inserts in each backing plate ensure secure, repeatable pad attachment
  • Durable Foam Construction: Washable sponge material withstands repeated cleaning and maintains structural integrity across extended use cycles
  • Black Plastic Backing Plate: Reinforced center housing distributes load evenly and prevents pad flexing during operation
  • Chrome-Plated Mandrel Included: Precision-machined adapter with M14 male threading for reliable one-tool installation
  • Maximum Operating Speed: Rated for up to 4600 RPM—suitable for both pneumatic and electric polisher platforms

Business Advantages for Resellers

  • Margin Play: Low acquisition cost with multiple applications (automotive, industrial, metal finishing) expands your addressable market
  • Shop Essential: Pre-polishing and high-gloss finishing are core services—this set is a must-stock item for any shop investing in polishing equipment

Why This Set Matters

Pre-polishing and high-gloss finishing represent two distinct operations with different pad densities. This 3-piece set eliminates the need for multiple machine setups or inventory of single pads. The threaded M14 connection provides a precise, repeatable interface—critical for consistent results across different operators and machines. Washability extends pad life and reduces operational cost for your customers, making it a practical, profit-friendly recommendation.

Reseller Value: Stock this set as a core finishing consumable for any shop running polishing equipment. Low cost, high demand, and proven durability make it a reliable margin generator.
