DWIKE24Pcs Carbide Hole Saw Kit,5/8'' to 3'' TCT Hole Saw Set with Upgraded Pilot Drill bit for Hard Metal,Alloy,Aluminum,Stainless Steel,Plastic,Iron

I’ve only had this hole saw kit for a few weeks now, but I have been very impressed with it. It’s a heavy-duty kit that drills through wood and thin metals in a matter of seconds. I like this kit a lot.The first thing I used this kit for was to drill through an electrical control box. Which is no easy task because the box is constructed from fairly thick metal. However, the 1” hole saw I used went through it with relative ease. The whole job took less than two minutes.My only concern at this point is longevity. I think this kit will perform well over time, but, of course, that’s just speculation at this point.However, if I come to realize that this kit just isn’t up to par durability-wise, I will be sure to come back here and let you know about it.If you have any questions about this Dwike ‎hole saw kit, please feel free to ask, and I'll try my best to answer. I hope you found this review helpful

I keep finding myself needing different size hole saws so I wanted to get a set of them. I was really just looking for bits that would work a handful of times each, but man these things are solid. I think they'll last a long time. They go through plate steel with no issues so far. Comes in a decent carrying case. Very impressed with these.

pro: multiple sizes for hole saws; extra pilot drill bits; comes in its own hard plastic carrying casecon: durability over time

I used the 24Pcs Carbide Hole Saw Kit and have been extremely impressed with its performance. The set includes a wide range of hole saw sizes, from 5/8" to 3", making it suitable for a variety of projects. The upgraded pilot drill bit ensures accurate and clean cuts through various materials, including hard metal, alloy, aluminum, stainless steel, plastic, and iron.  The carbide tips are incredibly sharp and durable, providing long-lasting performance. The kit also comes with a convenient storage case, keeping everything organized and easy to find. If you're looking for a comprehensive and reliable hole saw kit, I highly recommend this 24-piece set.

This set includes a total of 16 hole saws of different sizes. I was immediately impressed with the heft and quality of each saw. The machining is excellent, and they are properly designed and balanced, with no wobble. Titanium coating ensures longevity of the pilot bits, even when drilling hard steel. Those pilot bits are perfect for ensuring that the hole saw does not wander, but rather puts the hole exactly where you need it. The carbide teeth of the hole saw are designed with multiple angles that bite into whatever you are cutting.

The set includes 16 hole saws ranging in diameter from 5/8 up to 3" diameter and so should cover the needs of almost any DIY user. The tooth setting is a little bit unusual; every third tooth has no set. It is claimed this leads to faster cutting. I've tried a couple of the saws on construction-grade Douglas fir and also on some finer grained redwood. If there is a difference in cutting speed, it seems to be minor, but the tooth setting does seem to leave a wider kerf, which makes it a bit easier to dislodge the cut-out plug. There was some tear out on the exit side but that is to be expected. Four extra center drills are provided, which is a nice touch.

This is a exceptionally complete set of very nice carbide hole-saw bits availing sizes in 1/8" increments from 5/8" up to 3". They appear to be manufactured out of an above average grade of carbide steal tip that is incorporated into a heavy-gauge shell casing.The assortment arrives in a very durable plastic case that keeps all of the bits in the respective places for storage and for travel.

You may not use all the sizes, but when you need a particular size hole this kit will be ready. The blades are sharp and make clean holes easily. With so many sizes you'd be hard pressed no to be able to complete your task.
