THE FLAP DISC T27 VS T29, WHICH ONE DO YOU LIKE?
T29
Conically shaped flaps are angled at 10°，which is ideal for contour and edge work. Angled flaps provide the greater surface contact for a more aggressive cut. Most efficient when used between 15°to 25°angle.
T27
Flat shaped for working on flat grinding surfaces. Most efficient when used between 0°to 15°angle. Best choice for smooth finishing.
