Type 29 With Integral 5/8-11 Hub
Cubitron II technology, the hands down performance leader in grinding discs, is finally available in flap discs.
Flap discs combine the cutting ability of a coarse disc with the blending capabilities of a finer disc in a single unit. This is because as the disc breaks in, the abrasive on the edge of the flaps wears off somewhat, leaving a softer edge with more of the cloth backing exposed.
This softer edge has an increased polishing effect. As a result, a 60 grit flap disc will grind like 60 grit, but leave a finish closer to that of a finer grit disc.
Convex style Type 29 flap disc
Premiun grade Cubitron II precision shaped, oriented grain, ceramic abrasive means these high performance discs provide the fastest cut and extended life available for hard metal surfaces
Ideal for weld grinding and de-burring
These discs come with a standard 5/8-11 hub built right into the disc - just spin it onto your grinder
Note Flap discs typically provide a finish that is one grade finer than their actual rating
These 967A discs are the flagship product in 3M's flap disc offerings, and are a step up from the 500 or 700 series of 3M flap discs in terms of speed of cut and durability; see Related Products, below.
For those who insist, this disc is available without the convenient built-in hub by special order, although at almost the same price.
