8 in HS-DC Fiber Disc
The 3M 00672 is a non-woven abrasive disc built for surface conditioning on metal. Its very fine aluminum oxide grade suits blending, finishing and light cleaning tasks in automotive and industrial shops.
Sustained load behaviour
The open coating resists loading so the disc keeps cutting during extended passes. Aluminum oxide grain maintains a consistent scratch pattern without glazing when run at the rated 3, 000 RPM maximum operating speed.
Thermals noise and power
Fiber backing dissipates heat generated by friction, reducing workpiece discoloration. The unthreaded 1/2 in centre hole mounts quickly on standard back-up pads for vibration-controlled operation.

Questions about this item
How loud or hot does the 3M 00672 HS-DC fiber disc get during continuous use at 3,000 RPM?
The disc itself produces no noise or heat; both depend entirely on the sander motor and workpiece. Proper dust extraction and light pressure keep the surface cooler and reduce airborne particles.
What sander arbor and backing pad are required to mount the 1/2 in unthreaded hole on the 3M 00672 disc?
You need a compatible 8 in backup pad with a 1/2 in center hole and a matching arbor on your right-angle or rotary sander rated for at least 3,000 RPM.
Will the very-fine aluminum-oxide non-woven face of the 3M 00672 load up on older clear-coat or soft paint?
The open-coat, load-resistant design sheds dust well, but very soft or tacky finishes can still clog the web; light pressure and frequent cleaning extend disc life.
