I recently purchased an industrial grade spiral extractor for cutting tools and have been incredibly impressed with its performance.As a result of using this product I found that it easily removes broken screws and bolts without causing any FURTHER damage. It is made from high quality materials and provides great durability, making it a worthwhile investment for any workplace. However, it may be a little pricey for those on a strict budget. overall, this product is a must-have for any industrial and scientific environment..
