The USA Polishing Supply Grinder Extender is a fantastic addition to any industrial power TOOL setup. As my tests showed, it effectively extends the reach of my grinder, allowing me to access hard-to-reach areas and achieve a more polished finish. The product is well-made and durable with a sleek design that integrates well with my setup .The only downside is that it requires some initial setup and adjustment, but once that's done its smooth sailing. I highly recommend this product to anyone in the Industrial and Scientific fields..
