This extractor has saved me a lot of time and headache .Through trial and error, I found that this product worked really well on various concrete materials i was working with. The diamond tip is a game-changer and made clean cuts every time. The material is sturdy and durable. The only downside is that it is a bit pricey, but the results are worth it. Overall, I would highly recommend this product to anyone in the industrial and scientific fields..
