Review on JIUWU Combination Composite Drilling Tapping by Jim Prix

I purchased a combination composite drilling tapping tool for my small manufacturing shop .Unfortunately, this product did not meet my expectations in terms of quality. My analysis of this industrial and scientific tool showed that it couldn't handle tough materials like steel. It was a total waste of money. The ONLY positive thing about this product is its low price. However, when it comes to cutting tools, the "you get what you pay for" rule applies..
