JIECHENG Bi-Metal 4 inch Hole Saw with Arbor Mandrel for Cutting Wood,Cornhole Boards,Drywall,Plasterboard,Plywood,Steel,Aluminium,Brass,Copper,Zinc,Tin,102mm

I got this to install these: https://www.amazon.com/gp/product/B087JL1W9M/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 It is perfect!

Just an fyi need a 1/2 chuck to get this to work. 12v tools dont fit.

I disliked the fact that it took so long (>5 min) to even score the plywood! Not my 1st time using a hole saw either! Later cutting with a different brand hole saw, took about 20-30 seconds. it was as if the teeth were dull altho they felt sharp. Kinda like you were running the drill backwards!

Mine actually might be a touch smaller than 6 inches in diameter. If youre thinking of using this to cut recessed lighting can holes, like I did, you will have to ream them out after you cut, like I did.. Other makers make the saw slightly bigger than 6 inches. This one is small than 6 inches. Gave it 3 stars because it was not expensive.

Nice product came timely but no instructions

Bought this to drill holes for corn hole boards I make. Works decent for this task, but I would use it on metal. The spring on the drill is a bit odd and I am not really crazy about it... I honestly dont think it will last so not too worried about it. I am also not too crazy about how the drill holder mounts to the saw portion. The quality of the saw seems good and will last for my needs. Overall, for the price and how I use this, it works fine and I happy with my purchase.

Works as expected, great value for the money.

Worked wonderfully and I was able to do myself with ease

Threads on saw/bit failed on first use. Junk!

This came with the threaded hole way off and stripped out before the first hole was complete.
