Workshop Ref is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com and related sites.
What this means for you
When you click certain product links on this site and make a purchase, we may earn a commission at no additional cost to you. Prices and availability are controlled by the retailer.
How we choose products
Our goal is Spec → Kit: after you look up a size (for example a drill bit label or grit), we may show a set or consumable pack that is intended to include that size. We do not publish paid “best of” ranking lists or fake product tests as main content.
Product pages, images, and descriptions on Amazon are owned by Amazon or its sellers. Always confirm that a product includes the size you need before buying.
Other retailers
From time to time we may use other affiliate programs with similar commission structures. When we do, the same spirit applies: transparent links that support the site without ranking theater.
Independence
Affiliate relationships do not change our content rules: no fake reviews, no fabricated lab tests, and no requirement that you buy anything to use the charts and tools.
