I didn't expect much from a tap this inexpensive. I try not to buy cheap tools but, I needed something quickly and for a non-critical task so, I thought I'd give this guy a shot. It cut through cast iron so smoothly I had to back it out to make sure it was even cutting. It was and very cleanly so. I didn't need it to cut very deep less than 1/4 inch but I did use it for 8 through holes with no signs of it dulling. I've no proplem plopping this tap in the box with my collection of OSGs. I'm not saying it's likely the same quality BUT it did what I needed it to do for a great price.
