Overview
This 16” (400mm) resin-bond diamond polishing pad is built for high-production floor polishing—designed to refine scratches fast and finish clean on concrete, terrazzo, and cement-based surfaces.  

Best for
• Contractors running large 400mm plates who want fewer passes and a more even finish across wide areas
• Concrete & terrazzo polishing where a full grit progression is needed (50 → 3000)  

Features
• Size: 16” / 400mm diameter
• Thickness: 14mm (thick pad body for longer usable life)
• Wet/Dry use (choose the method that matches your jobsite dust-control setup)
• Grit options: 50 / 100 / 200 / 400 / 800 / 1500 / 3000  

Fitment
• Fitment: for HTC floor grinders that use 400mm (16”) polishing discs/plates
• Before ordering: confirm your machine takes 400mm (16”) pads/discs and the attachment style matches your plate system (photo-check is the fastest way)

Common questions
Q1: What grit set should I choose?
A: If you want a safe, standard polishing run, use 50 → 100 → 200 → 400 → 800 → 1500 → 3000.  

Q2: Is this for grinding or polishing?
A: This is for polishing/refining and can take a surface from scratch removal to high-gloss finishing depending on grit selection.  

Q3: Wet or dry—what’s better?
A: Wet typically runs cooler and can extend pad life; dry is cleaner for indoor work when paired with good dust extraction.
