What we do
Product names in this niche overlap even when the machines do very different jobs. We separate vertical-bit stained-glass grinders from flat laps, slant laps, wet belt sanders and cabbing machines, then explain the work each format suits.
What we do not do
We do not disguise manufacturer claims as personal experience, copy marketplace reviews or award unsupported ratings. Every review distinguishes verified facts from editorial judgement and links to its principal specification source.
Useful after the purchase
Our bit checker, grit planner, maintenance troubleshooter and material calculator are designed to remain useful at the bench—not only at checkout.
