1-3/16" to 7-7/8" Adjustable Hole Saw Circle Hole Cutter Drill Bit, Heavy Duty Wood Drywall Drill Bit Round Cutting for Woodworking, 30-200mm

Awesome circle cutter, this one cuts thru some of the toughest wood out there with easy and is extremely safe to use. I used this to cut a bracelet out of Purpleheart wood and it's some of the most dense wood if run across. It did an amazing job and still is sharp and working great. Thank you for making a product that works so well.

They sent an Allen wrench to tighten the ajustable parts. It came off even after I tightened it down past the stopping point. It cost me my 65" Fire TV. 😡.

Worked great to cut a precise 3 1/8' hole in 1/4" pvc sheet. Set-up is very fiddly. If you need a precise hole, use a caliper and measure, measure and measure again, and do a test cut. The fact that the arms are coated in thick paint doesn't help with the set screws, but I got it to work eventually and I like that this is not a one size only product. I used it on a drill press, and put a screen in front of it, for safety purposes. It's just that there are a number of metal parts held together by small set screws that are rotating at high speed right in front of you. Better safe that sorry!

Exactly what I ordered works well

Looks like it will work, well made and very adjustable but it's larger than you think and when it's spinning around on your drill press you'll think twice about safety and your fingers. I turned the press off, put it away and used a single arm style circle cutter I bought at the same time. I'm not saying don't use it just be prepared.

Used in a drill press, for cutting MDF.Granted, it was a large bore I needed (5-3/4"), but well within the advertised capabilities of the item.Not only did one of the blades losen with the centrifugal force (my press was set in 2nd speed, out of 5, in case that matters), but even after retightening, it as still the scariest thing I've used in my shop. I could not use it to cut the 1/2" MDF board I needed, instead I just used this item to score the outline and used a jigsaw for the actual cutting.I am not going to use this again. If you do, please exercise the utmost caution.

I returned the adjustable hole saw circle hole cutter because it wasn't compatible with the dust shield that I had purchased.

The blade on one side loosened and made a giant gash in my ceiling that is later than the diameter of the recessed light. Now it's going to look terrible. This is despite the fact that I made sure all the bolts were very tight prior to using. I would highly recommend not buying
