40-200mm Adjustable Circle Hole Saw Drill Bits Cutter Hardwood Plywood Hole Cutter Tool for Cutting Hardwood, Laminates, Rubber, Plastic

The center drill part of this is bent? The center drill bit can be removed with a setscrew. I tried to adjust the drill bit so it would not wobble, but could not. I used a drill press to cut 6 inch holes in luan plywood. In order to get it to work I could not clamp the plywood. I had to let the plywood float. The center was about 1/8 inch off, so, the plywood moved almost 1/4" while cutting the hole. I bought the tool for a one time use project. If I had more than 10 holes to cut I would have returned the tool. I got what I paid for, not much.

I would not recommend this for a Novice drill user. Most likely this tool is made for a drill press. It is very difficult to use with a regular drill. I was able to make my holes and they were the dimensions I needed them to be just had to go slow

I though a made in China product, use it once than chuck it. Not this, looks cheesy but it work just fine...

Spend a little extra to get a better product. I used this for 1 minute and I had parts flying off of it. It also advertises its use for a drill. The hole size I needed was bigger than my small drill press can handle so I used my drill with this and it gave bad results.

Got this for sheetrock. Very hard to use. Tried different speeds. Measurement marks off. Had to use calipers to set the side even. Still made hole bigger than intended. Not worth it. Ave your money and get a real hole saw.
