One of our Mexico customer sent us some samples of 180x6x22.23mm / 7x1/4x7/8 inch , those discs produced by one famous brand company in Mexico. We have done some testing and find the density really high and discs be very " Hard". This style grinding discs little difference like us- normally our customers like the discs be little " SOFT" with very smooth & fast grinding ability and comfortable hand-feeling . This just the difference between EURO and Latin America market consume style.
After study the samples, we have made some samples and the brief testing data as below. We already sent the samples for our Mexico customer testing and got OK feedback.
Below is some brief testing datas.

Before testing : 383.10g After testing : 375.30g Before test : 1792.80g After testing : 1553.50g
Grinding Time = 10 Mins Brief Testing Datas
Testing Discs = Blueshark Grinding Discs for Steel 180x6x22.23 mm ( 7x1/4x7/8 inch )

Powertools Data: Bosch 180mm
Total Testing Time : 10 Mins
Discs Weight Loss = 383.10g - 375.3g= 7.8g
Work-piece Weight Loss = 1792.80-1553.50=176.3g
G. Ratio = 176.3 / 7.8 = 22.6
S.G.Ratio = 176.3 / 10= 17.63g/min
Conclusion: High G.ration than ours normal standard also with the good hand-feelings.
