About Stone Tool Checker

Stone Tool Checker is a comparison resource for the tools stone fabricators, countertop shops, and concrete polishers actually buy — diamond polishing pads, cup wheels, and core bits. Our goal is simple: the neutral, spec-complete reference this niche has never had.

Editorial independence

We are editorially independent and neutral toward every brand. No brand pays for placement, ranking, or inclusion. Specs and comparisons are compiled the same way for every product, regardless of who makes it — and we'll say a product falls short even when that's inconvenient. Neutrality isn't a slogan here; it's the product.

Our relationship with Toolocity

In the interest of transparency: Stone Tool Checker is affiliated with Toolocity (Applied Diamond Tools, Inc.), a seller of stone-fabrication tooling. Toolocity does not own this site and does not control our rankings, spec data, or which products we include — it's treated like every other brand we cover. See our full disclosures.

How we make money

When we add cross-retailer prices, some outbound links will be affiliate links — if you buy through one we may earn a commission at no extra cost to you. Affiliate commissions never influence our rankings, inclusion, or the prices we show. Details are on our disclosures page.

Trust the data

Every spec we publish is traceable to its source — you'll find source links on each product page. See our methodology for exactly how the data is compiled and QA'd.
