Very good quality diamond blade particle. However it takes a saber saw 900 to 1000W minimum for efficiency. Cutting without water lubrication. It's better to play with the blade rather than simply apply a vertical or horizontal force, ie making small back-and-front / rear with undulations of the saw. A blade made me cut wall 2x 2.7 2x 2m brick and concrete. She is still diamond after that. Delivered within 2 to 3 days.
