Key Features
Overview
Mirka 23-622-040 Bulldog Gold Grip Disc is a 6 inch hook and loop sanding disc for aggressive material removal and rough surface preparation. This is a sanding disc designed for coarse sanding, stripping, and early-stage surface prep. Model Number: 23-622-040. If you need a disc that cuts fast before you step into medium and fine grits, this is the kind of abrasive you reach for first.
The big story here is the P40 grit. That is a coarse sanding grade meant to remove stock quickly, clean up rough surfaces, and get through heavier prep work without wasting time. On the job, that means less time trying to force a finer disc to do a roughing disc’s work. If you are flattening filler, knocking down old finish, or starting on rough wood or other work surfaces, this grit gets you moving.
Mirka builds this disc with aluminum oxide abrasive, which is a dependable choice for general sanding work. It is widely used because it balances cutting performance with reasonable disc life, and that matters when you are burning through abrasives on larger prep jobs. The semi-open coat construction is also worth noting because it is intended to help reduce loading, which means the abrasive stays working longer before dust buildup starts getting in the way.
This disc is part of Mirka’s Gold series and uses a grip face backing, which is Mirka’s hook and loop attachment style. That gives you faster changes than adhesive-backed discs and makes it easier to swap between fresh discs or step through your sanding sequence. For anyone running repeated sanding cycles, that convenience adds up fast.
The disc diameter is 6 inches, and this version is a no-hole design. That matters because hole pattern is one of the first things buyers need to confirm before ordering sanding discs. If your setup uses a solid pad or does not require dust extraction through the disc, the no-hole format may be exactly what you need. It is important to match the disc to the pad and machine setup you are actually using.
This pack includes 50 discs, so it makes sense for users who go through abrasives regularly rather than someone buying a one-off replacement. Cabinet shops, body shops, refinishers, woodworkers, and serious DIY users doing a lot of prep work will get the most value here. If your work starts with heavy sanding and quick stock removal, this Mirka sanding disc is aimed right at that part of the job.
