Is it cheaper to buy or rent a concrete grinder?
Break-even days to buy vs rent a concrete grinder — from daily hire rate, purchase price and how long you need it.
Quick answer
Concrete grinders for flooring/resin jobs sit in a wide band — roughly **€3,000–15,000** new vs **€80–650/day** daily hire. Break-even ≈ purchase ÷ rent: **€8000** ÷ **€180/day** → **44.4 days**. A **5-day** project totals ~**€900** in hire — buying a pro unit only pays if you grind floors every month.

Frequently asked questions
When does buying a concrete grinder pay off vs renting?+
Break-even is roughly purchase price ÷ daily rent. At €8000 to buy and €180/day to rent, that is about **44.4 days** of use. Fewer days → rent; more → buy (if you will use it again or resell).
Should I count resale value when deciding?+
Yes for quality tools you sell after one job — enter expected resale in advanced settings. Cheap or disposable gear often has near-zero resale; then use full purchase price in your head.
Why are consumables the real cost on floor grinders?+
Belts, abrasive discs and diamond segments wear out every job — a weekend hire might burn through €80–200 in abrasives alone. That is why we link Amazon consumables, not the machine: pro grinders are rented or bought from dealers; pads and belts are what you reorder repeatedly.
Can I buy this machine on Amazon?+
Not the full pro class — Amazon lists small DIY sanders and accessory kits, not 200+ kg rental fleet grinders. Use this page for break-even math, get machine quotes from rental yards or flooring suppliers, and buy abrasives online.
