Every crew has been here. A cup wheel seizes onto the grinder from heat, a bad fit, or missing a spacer that got skipped. Now someone's out there swinging a hammer and chisel at it, praying they don't damage the cup wheel, grinder or both.
Ten minutes later, that cup wheel is trash. The grinder might be too. Now someone's driving to the store, dropping another $150 - $400, and your crew just lost a chunk of the day standing around instead of working.
Kup Keys were designed and created by someone who experienced this exact problem, more than once, and got tired of losing money and time over it.
The Kup Key is ONE adjustable tool that adapts to fit different cup wheel sizes. Now you're not carrying a tool bag full of spanner wrenches, hammers and chisels that don't efficiently solve the problem.
Insert, turn, and the cup wheel releases. There is no damage to the wheel and no damage to the grinder.
We have shown this tool to guys who've been in the trade for decades, and the reaction is always the same. A foreman who watched him remove a seized cup wheel in seconds, called it "ingenious", he demonstrated it to his whole crew, receiving the same response. Two other customers who saw it work, each bought a Kup Key on the spot.
Who We Made This For
Built for anyone operating a grinder: concrete polishing crews, coatings installers, slab and flatwork guys, and anyone doing profiling work, Whether you're one guy with one grinder or running a crew of ten, if you've ever lost a cup wheel or grinder to this problem, this Kup Key is for you.
No. A spanner wrench only fits one size. Kup Keys adjusts to fit multiple cup wheel sizes, so it's the only tool you need in the tool box.
Yes. It's built the same way the grinders it works with are built: for daily job site abuse, not a one time use.
You'll get real support from someone who's actually used this tool in the field, not a call center reading script.
