Buying Guide

Match pad size to your polisher

Choose 4-inch pads for handheld polishers and 6–10-inch bonnets for waxers to ensure correct fit and coverage without overloading the motor

Pick wet vs. dry pads by material

Use wet diamond pads (resin-bond) for stone and tile polishing and dry diamond pads for granite, marble, and quartz where dry grinding is specified

Check grit range for your task

Lower grits (e.g., 50–100) remove material faster for leveling; finer grits are for honing and polishing to a shine, so buy multi-step sets when possible

Consider accessory and storage options

Tools that include a carrying case or a variety pack of pads improve portability and organization for mobile detailing or jobsite work

Balance runtime and duty cycle

For continuous use, prioritize polishers with appropriate motor cooling and choose pads sized to avoid excessive load that shortens tool life
