Hole Saw Kit, SUNGATOR 5-Piece Set. Specially Constructed Heat Treated Carbon Steel, High Precision Cutting Teeth. Cut Clean, Smooth, and Precise Holes Through Wood, Plastic, PVC Board and Drywall.

I read many reviews, and I went for it. There are cheaper sets, however I liked the case design so I went with this. I used the 1-1/4 bit a lot making holes in plastic 55 gallon drums for a rain barrel project. One of the reviews mentioned that they needed a socket to remove the arbor from the hole saw bit. I hope that person hit it with his purse fist, that usually loosens them. Here is an easier way, remove the bit, loosen the grub screw, then put a smaller screw driver through the side holes and remove the hole saw bit. Not hard right? That is because its not hard! Are there better bit locking designs? Yes, in this kit when you use the larger arbor its an easier design to remove it. Some reviews you need to understand the authors skill level.

I used this to cut a hole in a sink and it work very well .

These are not bad at all. Only reason why people keep saying it became dull is because they overheat the bits. Probably not using it with impact drill. I used it with regular drill and it worked perfect. I used it on my desk. I just had to do it for a few seconds, then spray some water and repeat. It came out great. It took about 10 minutes to drill the 1 inch thick desk because after about 2 minutes, it gets really hot. I had to dip it in cold water. If you dont cool it down and keep going, teeth will become dull due to heat

The battery dies in my Barska gun safe and they gave me the wrong emergency key. I pulled out my hole saw and I was in my safe in 5 minutes and the hole saw is still cutting like a champ. Doesn’t say much for Barska but these hole saws are great.

I had a home improvement project to do. I like wired internet because it just seems slightly faster than wireless. I have gigabit service so wired speeds are absolutely blazing. 900 mps up 900 mps down smoking fast for me. Ive been working from home and will be for the rest of my career. Working from home means two more laptops added to my four gaming computers. My home router is in my bedroom. My home office is in a section of my living room. I had to drill through two walls to bring more cables though from bedroom to living room. I did not want the job to look tacky or ghetto. I brought Construct Pro Speedy’Z Spring-Lock 2” Cable Pass Through Port (White | Each) from Amazon.com. These cable pass throughs from Amazon.com and they look nice. The hole it covers is like 1.5 inches so I needed the ability to drill a 1.5 inch hole. This collection did the trick. It has a 1.5 inch circular hole option. It was easy to put onto my power drill. Sharp enough to cut through 2 hour fire rated drywall like butter. I have no complaints about this product. Did exactly what I needed in the quality trouble free way I expected with no fuss at all.

Before purchasing these holesaw’s I had never heard of this company but I figured for the price I would give them a try. I was pleasantly surprised, these saws are extremely sharp and cut through wood very easily. I have even used them to drill through the steel back of my toolbox, I don’t even know if the saws are rated for metal but they did cut it without dulling the blade. I have been very impressed with these and if I manage to dull or break them I will buy them again.

The set does everything I need it to do. I have cut the 7 holes I needed to get done, and they all went easily. BUT... like others, I wish the smaller pilot would fit a 3/8 drill. Like others, I had to use a 1/2 drill for every hole, whether the small pilot or the larger pilot. So it missed 5 stars throughout simply because a few thousandths on the small pilot made me use a much larger and heavier drill to drill a 3/4 hole. The saws cut well... low speed, cutting oil for the metal, and no discoloration or loss of edge that I could see.
