I read other reviews and I knew Aircat make good products and this cutting tool is no different. As a diesel technician I use this quite a bit and am very impressed so far. Quiet for a parting tool, it still has enough power to cut a variety of materials. I've used it at home with the compressor set at 90psi and it cut 1/4" thick steel like butter. I'd say some of its performance is enhanced by a good quality cutter wheel. Overall very happy with the purchase and would recommend it to anyone starting out in the automotive industry for the quality and price.
