4) ADDITIONAL INFORMATION: 

a) TURBO style available--Coated 30% more abrasives than standard !!!

b) BLUESHARK produce flap discs with different backing plate:
*Fiberglass backing plate - Most popular and it's can reduce vibration and is consumed together with the flaps. High strenghth with light weight.
*Plastic backing plate- With very nice lookings and is trimmable to increasing service life. The ABS plastic backing with very high strength and supply mas safe working performance. Spin-On style also availabel.
*Nylon - Very familiar with plastic backings but with more light weight.
*Metal HUBS: provides extra high strength and rigid support as needed and normally using for heavy task . Also it can be recycled. 

c) Grit size recommendation

    40#--Aluminum ,Unalloyed and low-alloy steels,low-strength stainless steel

    60#--High-alloy,stainless steel,high-temperature and heat-treated steels

    80#--High-temperature alloys

   120#--For especially smooth steel finishes(refine polishing)    

d) Best working angles

     (15~30')                               (0~15')

For best performance , keep 15~30' when grinding and 0~15' while polishing & finishing.

e) If using flap discs replace fiber discs workings, you should choose one grade coarse grit size. Such like you should using 80# flap discs if 

normally using 60# fiber discs.
