Key Features
Overview
The Mirka 40-624-080 Coarse Cut 6 in Grip Sanding Disc is a hook and loop sanding disc built for aggressive stock removal and surface prep. This is a sanding disc designed for coarse sanding and fast material removal. Model Number: 40-624-080. If you need a disc that gets through early-stage sanding work without babying the tool, this is the kind of abrasive that earns its keep.
The key spec here is the P80 grit. That puts this disc in the coarse-cut category, which makes it a practical choice when you are leveling surfaces, knocking down rough material, or stripping back a surface before moving to finer grits. It is not for final finish work. It is for getting the surface where it needs to be so the next step goes faster and comes out cleaner.
The 6 inch diameter matters because it matches a very common random orbital sanding format. That gives you solid coverage on larger work areas while still keeping the tool manageable in hand. On bench work, panels, and other broad surfaces, a 6 inch sanding disc helps you cover more area per pass than smaller formats.
Mirka uses a grip-style backing on this disc, which means quick attachment and removal on compatible hook and loop sanders or backing pads. That sounds simple, but on real work it saves time every time you step through grit changes. Instead of fighting adhesives or slow changeovers, you pull the old disc, press on the next one, and keep going.
This product is sold in a 25-pack, which makes sense for users who go through abrasives regularly. If you are sanding in batches, working through repeated prep steps, or keeping commonly used grits stocked in the shop, buying discs in a pack like this is a lot more practical than chasing singles.
The Mirka 40-624-080 Coarse Cut 6 in Grip Sanding Disc is a good fit for painters, woodworkers, remodelers, body shop users, and serious DIYers who understand where coarse abrasives belong in the process. If your job starts with rough stock, old finish, or uneven surfaces, this is the kind of sanding abrasive you reach for first, not last.
