    Bought this a I had 12 holes to drill in 1/2” drywall to install surface mount LED’s. On 1st hole the bit snapped and damaged my ceiling as it skipped across the ceiling. I sent it back and used a hand drywall saw instead. Wonder what would have happened if I attempted to cut plywood. They did refund me my money.

    I bought this hole saw to use for the construction of some washer boards. It cut all the holes very clean and worked great. I have not used it on metal yet but on the plywood it cut it like it was butter.

    Product was not square, causing it wobble.

    First.. Dont expect the parts to be compatible with your current hole saw set up. My others are mix and match; this one is different. But it does come with all the parts needed to put it into surface. . Second... I dont plan on many cuts, most will be in drywall. It should be fine for that purpose. You will have to provide your own dust protection or cleanup after words. 6 makes some drywall dust. . Third.... It worked perfect for the LED flush mount lights I bought here on amazon. I didnt worry about a dust catcher since I was in process for other things in the room.

    There are a lot of review that say the blade dulled after one cut, or the threads stripped, etc. I had none of those issues. I bought this to drill holes in my RV floor, which is 3/4 plywood. Four successful holes later, its still pretty sharp and totally usable for future projects. You do have to watch when you stop the drill that if the saw is in free space, inertia will keep it spinning and it will unscrew from the arbor. After I cut a few holes, it was firmly screwed down to where I cant even unscrew it anymore, so the unscrewing was a temporary problem for me. I guess because I was expecting something unusable, I am really pleased with how it worked. Not for cutting metal for sure, but if you just want a few holes in plywood or sheetrock, this is a great cheap alternative.

    Heavy metal, substantial. Spring is a nice feature for removing slug.

    I wouldnt recommend this product. This is heavy metal saw but doesnt do the job. Shank is too short for two of my drills and also slips (danger).

SHARP SAW

The sharp teeth is HSS M42 Bi-metal saw,it can open hole in shorter time with neat opening.

BETTER CENTER DRILL BIT

The center drill bit is higher quality, sharp with split tip, it can drill the holes very fast. and stronger.

OPERATION

The shank is 3/8 inch, it is good for most of the hammer drill.Please be sure to tighten the thread between arbor and hole saw when assembling.

Advantage:

1.Sharp and strong to make holes on all kinds of wood,metal

2.This 4 inch hole saw is cheap and cost-effective. It can finish the work with as little money as possible

Notice:

1.When starting drilling,please firstly cutting at a slow speed, after the teeth go into the material,then use the normal or high speed.

2.The hole saw is sharp, so it is dangerous,please be careful,and not let children touch it. and please be sure to tighten the arbor with hole saw.
