Worth the money! Great hole saw kit.
Genuinely a great set and super sharp. Cut though 1/4inch stainless in less than a minute and wood like it’s nothing.

Beast mode tool for sure
Awesome results cutting thru 1/4 mild steel. I was shocked but how good the bits did. 100% recommend!

Storage case not included
What a spectacular deal! They work great and cut fast. My biggest and only complaint is that they show a carrying/storage case in the ad.. I got a big box in another box and no storage case And although they did come individually packaged in their own plastic tube, It's makes them very hard to store if you don't have a dedicated drawer to put them. This is the only reason for the 4 star rating, the cutters are good so far.

Buy Once, Drill Holes, Get Back to Your Life
This hole saw set does exactly what tools are supposed to do: it works hard, doesn’t complain, and doesn’t require a second purchase to fix its shortcomings. The carbide cutters chew through metal and steel cleanly and efficiently, without the drama, smoke, or premature dulling you get from cheap bi-metal junk. I’ve used multiple sizes from the set and they all cut straight and fast with minimal vibration. The carbide teeth are properly attached (a low bar that many tools still trip over), and nothing feels flimsy or disposable. This is gear meant to solve a problem, not create a new one. The kit is sensibly complete — useful sizes, solid arbors, and a case that keeps everything organized so you’re not rummaging around like a raccoon in a toolbox. That matters when you value your time as much as your money. For the price, this set punches well above its weight. GSTK managed to deliver something that avoids the false economy trap: cheap tools that fail and force you to buy twice. If you want reliable performance, fewer trips to the store, and holes drilled without nonsense, this is a smart, five-star purchase.

Sharp and good value
Good value. Sharp. We will see how they hold up over time.

Excellent!!
I used some cutters like this for many years. They require oil to to be applied while in use. Don't forget that and they will last a really long time. My other advice is do not lend them out because no one cares about your tools and you will be the one replacing what they damage.
