Review on 🔎 Spyder 600887: Premium Bi Metal Hole Saw Set for Precision Cutting by Sean Flint

Do not buy this product! There is a serious problem with this hole saw system. If two hole saws are used simultaneously to widen a hole, two saws will get stuck in the mandrel. Good luck with the removal. I had a set of 14 pieces of metal, I had to enlarge the 2"1/8" hole to 2"1/2" through the 1/8" metal. It drilled a hole ok but after I did it I couldn't remove the saws from everyone else I tried heat gear oil adjustable pliers swearing nothing happened Out of desperation I used a vise Couldn't move them yet Eventually I gave up and it thrown away. It took me half a day of work in delays to get my job done. Never again! The scary thing is that there is almost no place to grab the inside saw to remove it would be very easy, a finger or a Losing hand when trying to separate them Looks like I'm not the only one having this problem, this item needs to be taken off the shelves I've used them on a slow drill also some wax to use Lubricate used and YES The S pins were pulled out completely when trying to remove them. There is no contact with any saw holes. They seemed to be welded to the central axis threads and stayed there.
