The hole saw cutters appear to be fairly well made, however, the finish is not what it should be, typical of Chinese workmanship. They should make a hole in thin sheet metal without problem. I have my doubts of them being suitable for any type of production work.

If you just need holes in thin steel less than 1/16 inch likely you can get many holes drilled. Anything thicker it is good for maybe two holes before the bit teeth break. You get what you pay for. I mainly bought this set to drill one hole at 25 mm (.98 inch), in 3/16th metal, it worked, I did try to drill another at 25 mm the bit made it half way through the 3/16th steel plate before it disintegrated. I could not find a Hercules brand hole bit at one inch, so I bought this kit. The Hercules 1 1/8th size bit plows through 3/16th metal very quick without damage to the bit. I still have other various size holes to drill in thinner material so I am not dissatisfied with the purchase of this kit, it meets my needs. Price was right, did the job!

Nice set. They have a spring inside to push out the plug after it's sawed through. If you use a coolant, not an oil, they will last a long time. Oils are to keep heat in. Coolant is just a little soap, ten drops in a cup of water, and they will cut forever almost with little pressure. These are for metal cutting for me although I understand that probably most will use them for wood? For the price they are a super deal.

And was very pleasantly surprised I took it slow and use W-D40 and the hole was nice and clean tool shows no damage. I think i will get a lot of use out of these.

Thought I'd try these Cutters....I knew they were very inexpensive, so I wasn't expecting them to be very tough. I have used 1 of them and worked it pretty hard. Did a good job. Even when i jammed a tooth, it didn't break the carbide cutter tooth on the Cutter. I was impressed. I would buy them again, if needed. Decent Tools!
