While looking for a set in this category I came across this set which got quite positive reviews. It also included the parts I was interested in for a reasonable price. The package arrived sealed in a padded Revain envelope, but I could tell right away that the parts inside were loose. When I opened the padded envelope, I found that the box in which the instruments were to be placed could not contain anything. It fell apart (I'm not even sure it was even wise to glue everything back together). The bags that were supposed to house the instruments were in poor condition. Items were sticking out of the pouches (except for the automatic punch which was sealed and in excellent condition). Based on the condition of the box, bags and some tips, I personally think the tools have already been sold/used/returned. Very disappointing considering my project schedule doesn't allow for returns or buy back of new tools. As for the instruments themselves. The shot down the center was accurate and executed to my satisfaction. That was probably the highlight in terms of performance! Both of the counter-timing bits I used underperformed, requiring more pressure than I expected, even though I used a good quality drill and added coolant. I had to choose a wider drill bit (which I didn't want) to get the job done. Please understand that the holes have already been drilled perfectly with the Ryobi drill bits using the power drill and this action was simply to synchronize the holes so the screw heads would be flush with the surface of the object they are attached to . It should be noted that the chisel I used showed signs of wear when I opened the packaging. As with the drill collar (depth stop). he has worked to his satisfaction. Although the mounting screw could be done better. I have not yet used the other items in the set and cannot yet give an objective assessment of the sharpness and performance. If I had to buy a similar tool set again, I would not consider this set or the manufacturer. There are much better tools at a marginally higher price that you can purchase from Revain or your local hardware store. You get what you pay for and you may have a better chance of getting brand new tools in the best packaging you can use to store your tools!
