REETAI-FOUR 10Pcs TCT Hole Saw Kit,Tungsten Carbide Tipped Hole Saw Set, Hole Cutter Heavy Duty for Stainless Steel.(5/8-2-1/8”).

This item has proved to be used for many occasions when needing to make a hole for anything all the teeth on the circular saw does not appear to be sharpened enough to immediately pierce through metal eventually, after some time I was able to break through the metal needed access to still for the price I would recommend to anyone

These hole saws are fairly tough but beware of a few issues. First the Pilot drill bits are much to hard and brittle and under the load of drilling a larger hole can break easily. The other issue is that since these saws use welded on carbide chips, they are fairly wide and therefore cut a wide kerf and means the drill needs to be pretty heavy. In metal the saws also like to grab in material so be careful. This is also when the bit usually gets broke. All in all the price is right as long as you are aware of limits.

The drill bits have this nasty habit of unscrewing with use. If everything holds together these drill bits work fine on light weight metal studs. If you are drilling through the old thicker metal studs you will need an impact drill in addition to this item.

Drills bits shattered as they touched cold steal, but the outer cutters remain strong

Absolutely all garbage. Drill bits break as soon as it starts to drill through. Teeth break up on 26 gauge metal. Terrible product..

Does a great job. They are made for a drill press only. If you use a hand drill and drill like you normally would do with a hole saw you will break the teeth off of this type of hole saw. Glad I bought a full set. Jim

These are the cheapest made junk you’ll ever buy, please save your money and buy a quality set! I am a professional machinist so I know what lubricants, coolants, cut rates and so on to use I do this day in and day out and the first bit I used lasted 4.5 seconds before it sheered in half by twisting the shaft right off!

The cutters have worked adequately for the hobbyist projects, but be careful to use the right RPM, pressure and some sort of cutting oil to keep the teeth from overheating. The only complaint is that its hard to tell if the teeth are the same depth or there is a lot of runout relative to the shaft.

I’ve only used a few of them. They worked well with 3/16” steel plate. They’ve had a little trouble with drilling bed rail (which is harder than standard steel).

Took several bit to get through concrete.
