Full coat up to mandrel screw. Perfect for my application First time I ordered this product there was nothing in the package. This was due to bag being unsealed, so they sent me a replacement. Already disappointed, I hated the product before I even got it. When the replacement arrived, I got to work on it right away and it exceeded all my expectations. Does what it needs to and grinds effectively. The only Full disc Ive found, make sure its the 35mm when you order for the full sand, 25mm isnt full. Thank you for providing this product!
