SALI 4" Diamond Polishing Pads 10-Pack — 30-Grit Wet Stone Cutting for Granite & Marble

SALI 10-pack 4-inch diamond polishing pads are aggressive 30-grit resin-bonded pads designed for wet polishing and rapid material removal on granite, marble, concrete and other stone surfaces.

These pads pair diamond abrasives with a durable resin matrix to deliver fast cutting action while maintaining pad life when used with water. Packaged as a set of ten 4" (100 mm) pads with hook-and-loop backing, they install quickly on drills, angle grinders, and polishers so you can prep, reshape, or denib stone countertops, floors, and edges before moving to finer grits.

What surfaces can these 30-grit pads handle effectively?

The SALI 30-grit pads are made for heavy stock removal and surface leveling on hard materials. They work well on dense natural stone and engineered surfaces where aggressive cutting is needed before finer polishing steps.

• Granite: fast removal of lippage and scratches
• Marble and terrazzo: edge shaping and flattening
• Concrete and cementitious overlays: smoothing and prepping
• Quartz and vitrified tiles: initial grinding before finer grits

How do I use these pads safely and get the best results?

Use the pads with continuous water flow to reduce heat, carry away slurry, and prolong pad life. Choose a variable-speed tool, match the tool thread or adapter, and keep even pressure and motion to avoid gouging.

• Operate at recommended RPMs for your tool and material
• Maintain a steady overlapping pattern for uniform removal
• Keep the working area wet to minimize dust and heat
• Check pad wear and replace when diamonds embed or dull

Which tools are compatible with these 4" hook-and-loop pads?

The pads are designed with a hook-and-loop (Velcro) backing for quick attachment and removal, making them compatible with most handheld rotary tools and small polishers. Confirm the backing pad size and spindle adapter of your tool before mounting.

• Variable-speed polishers and grinders with 4" backing plates
• Angle grinders with appropriate backing pad adapters
• Hand drills fitted with a 4" backing pad or adapter
• Use anti-kickback, splash guards, and proper PPE

How long will one pad last and when should I replace it?

Pad life depends on the stone hardness, pressure applied, and water usage. On dense granite or aggressive tasks, expect moderate life; lighter prep work on softer materials yields longer service. Replace a pad when cutting slows noticeably or diamonds are worn flat.

• Short life under heavy-pressure cutting on hard stone
• Longest life when used with consistent water lubrication
• Rotate pads in the set to spread wear across pieces
• Inspect for resin glazing or clogged diamond segments

Who is this for? SALI's 10-pack 4" 30-grit diamond pads suit countertops fabricators, renovation contractors, and DIYers who need a reliable, hard-cutting pad for stone preparation. If you shape, level, or remove deep scratches from granite, marble, engineered stone, tile, or concrete surfaces and plan to work with wet methods, this kit gives multiple ready-to-use pads with quick hook-and-loop changeover for workshop or on-site jobs.
