    Very dull. Threads need to be reversed so the arbor doesnt go spinning off. Just made it through 1 hole in 1 press board. Would buy again.

    It didnt cut my test piece of wood. Also didnt fit my corded drill, I had to borrow a cordless drill. Why the chuck was slightly bigger on the cordless drill than corded drill, I dont know.

    Needed to cut one hole in my soffit foot an exhaust fan. Did the job, though if I needed to cut more holes I’d buy something of better quality.

    This will not fit either of my black and decker 3/8 drills. I contacted the company and this is their response: Hello ,thank you for your feedback, we dont find your video or picture , but i send you some pictures in attachment of the 3/8 arbor, you can see we measure the distance between two sides, please note it is two sides not two corners. this is the customary standard in the hardware tool industry. another question is to see if your chuck of electric hand drills is marked 3/8, sometimes the chuck is not standard too. so there are many reasons for this. in fact we are company in China, no branch in USA, so we cant send you another pcs for test. but if youd like to buy this stronger arbor, maybe can be better, but not sure if it fit your chuck, the link is : https://www.amazon.com/dp/B081VQQQT4?ref=myi_title_dp . and another way is that if can not use it, please return this item to amazon. sorry for it. and hope you have a nice day! regards Jack The three pictures showing the measurements are the pictures mentioned in the response. The key point is the measurement of the arbor is not point to point, its side to side. It might fit most 3/8 chucks but not all. Good luck.

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.
