5 in Electroplated Diamond Grinding/Polishing Pads - 70/80 Grit

In this review the 5 in Electroplated Diamond Grinding/Polishing Pads from EDiamondTools prove to be a focused choice for tradespeople and serious DIYers who need a durable abrasive for stone and concrete surfaces. The bottom line: these velcro-backed, electroplated pads deliver consistent material removal and a long life on tough jobs where a 70/80 grit cut is appropriate. The review highlights that the pads work wet or dry, have a 3mm segment height for sustained performance, and attach securely via hook and loop for quick changes during polishing or grinding runs.

Key Features

• Electroplated construction: offers a rigid diamond matrix that stays sharp for aggressive grinding on concrete, granite, and other stone surfaces.
• Velcro-backed attachment: the hook and loop backer lets users swap pads quickly on polishers and angle grinders without fiddling with fasteners.
• #70/80 grit size: provides an efficient mid-coarse cut that removes material and levels surfaces while preparing for finer polishing stages.
• 3mm segment height: gives a measurable amount of diamond on the pad for longer life and consistent abrasion across the pad face.
• Wet or dry use: the pads can be used in damp or dry conditions, offering flexibility for different site setups and dust-management preferences.

Who It's For

These pads are best for professional stone fabricators, concrete contractors and serious DIYers who need a robust mid-grit pad for shaping, leveling or initial surface preparation on granite, marble, terrazzo, pool plaster and concrete. The pads suit users who already run polishers or grinders with a velcro-backed interface and want reliable, repeatable performance.

Those who need very fine polishing or final gloss stages should look for higher-numbered grit pads designed for finishing rather than 70/80 grit, since these are intended for material removal and surface leveling rather than final polish.

Pros & Cons

Pros

• Durable electroplated diamond layer that maintains cutting ability through heavy use.
• Velcro backing makes pad changes quick and keeps the pad secure during operation.
• Versatile wet or dry capability allows use across different jobsite conditions.
• 3mm segment height balances life and aggression for mid-stage grinding tasks.

Cons

• At 70/80 grit these pads are not suitable for final polishing or high-gloss finishing steps.
