As usual this Shaviv product is a high quality and well designed product. I also appreciate Shaviv as a company whose products are not made in China. For long reach deburring, this is the right tool for the job. For some of the parts that are made where I work, this is the only way. It has a usable range of approximately 0.700 inches/1.8 centimeters. As a professional, I highly recommend this product.
