Koopi 4.25 Hole Saw with Heavy Duty Arbor, 38mm Depth Bi-Metal 4 1/4 inch Hole Cutter for Easily Drilling Wood, Plastic, Plywood, Drywall, Thin Metal (108mm)

everything

This was purchased to drill a vent hole into the side of a dryer. With a little cutting oil, the holesaw cut right through the outter and the inner panels. Now Im not saying that this tool would cut the same holes all day long, all I am saying is the tool did what I needed done, which was a 4 hole in the side of the ol;d bags new dryer. Pressure off. Well worth the price.

Fast shipping exactly what I needed

Arrived safe and sound, used it to cut sheet steel. Easy cut through.

This product came disassembled, with no instructions in the box. Ive been in construction for forty years, and Ive used lots of tools with arbors. But this arbor was a new one on me. I tried for a half-hour to figure out how to put it together. Finally had to go to computer and take a close look at the item on the Amazon page. Also, be aware assembly will probably require use of a pair of split-ring pliers. Once assembled, it did a good job cutting through 1 pine siding and 1/2 flakeboard sheathing using only a P-C cordless drill. Be aware, though, that advertised 1 1/2 cutting depth is shall we say optimistic. Id say 1 1/4 is more like it. For example, I dont think you could cut a hole through a 2x4 without coming at it from both sides.

Sawed over 100 holes thru wood for a ice-cream cone craft stand. Worked perfect.

I broke my arbor and bought it with the hole saw. Great deal!

Is easy to use does a great job. Thanks.

before I ordered this I read the reviews, one person said teeth broke off just trying to saw sheet rock, so I went to hardware store and it was almost $50.00 so I thought I will take a chance on this one for half the money,sure glad I did I just cut through the floor 5/8 sub floor on 1 lumber went through like butter saw looked perfect after I was done, dont be afraid of this because of price, it tough!

The hole saw diameter was perfect. The hole saw tool seemed of very good quality. But. But it will fit only 1/2 drills, not the more common 3/8 that I have (nor the smaller 1/4 size. My goof. The small print specifies this.
