Flap discs are one of the most versatile grinder accessories in metal working. With a light hand you can lightly sand and polish an area then with some elbow grease, you have a metal removing machine. Flap discs do not wear out as fast as typical grinding wheels. As the disc wears it reveals a new piece of gritted sand paper behind it. Since discovering flap discs I tend not to use anything else for my metal grinding and sanding needs. They save time and last!
Diablo offers a variety of grits and styles of flap discs, but I have to say the rounded corner design of the Corner Edge flap disc is one of my favorites. It allows you to get into the corner of a joint to clean up the bead. While we were testing this disc we realized that you can actually cut metal with this disk. It is a beast for almost any application. You can see in the video how it cut and how long it lasted.
If you’re in the market for some new flap disks and want great performance with long life, check out Diablo.
Great writeup Dan!! I really need to invest in a angle grinder, there is so many things you can do with it, there are discs for everything! I really like that this has a feature for corners.
WOW ! They look great ! the corner disc is realy nice , but for finishing i like the see thru flap disc . Keep up the good work !!!! ????
See thru is nice }
Thanks for introducing me to these. I had no idea that flap discs can destroy metal that much and that quickly and last. I only thought they were those cheap drill attachments.
FLAP Disc, sounds like a plan Dan. Gotta get me some of those. Love grinding the heck out of things.
Chase when you get one , get a good one cose cheap angle grinders vibrate too much ,and get one fast its a must have tool 🙂
