A cheap disk, the "standard" line is the second after the worst IVF. The quality is appropriate. The diamond segment is not high, there is little abrasive in the soldering, i. E. for works on soft and average hardness of concrete, a brick. Reinforced concrete, or high-strength concrete will not pull. If you take for home and low-intensity work, then completely. For more serious work, other rulers are needed. The price is interesting only promotional, the full price looks stupid. 1500 and more for such quality is very, very much. Gentlemen from Bosch, as always, consider us a country of the 3-7o of the world, but they do not hesitate to earn quite serious money on any malignant equipment. I DO NOT RECOMMEND TO PURCHASE
