Adjustable Hole Saw Cutter Kit 1-5/8" to 8"（40-200mm）Twin Blade Hole Saw with ABS Dust Shield for Making recessed Lights, Speaker Holes or Ventilation Holes

This is a must have if you are installing recessed lighting in your ceilings. Very well made and will last for a very long time. This is not a "one-time" use tool. The saw also makes clean up a breeze with the included dust catcher that traps the drywall dust and keeps it from flying everywhere. This saw can make just about any round hole that the home owner may need - 1-5/8" to 8" (40-200mm). The case is also an added value. If the truth be known, the case is what sold me on this item. I like to have my tools protected and in there place after using them and the case does just that.

Likely a one-time use tool, but worth every penny. I used it to cut in 24 openings in my lower level project. The holes were perfectly cut. If you take the time to measure accurately AND take your time, ensuring you start your cut with light, even and level pressure, it cuts great.

They contain the dust well, adjusting them to the size you are looking for is a little tricky. It does chew the drywall paper a little , This can be remedied by cleaning the hole with a sharp blade. Other than that the contain the dust very well!

The bit broke on the first use. The bolt that supposed to hold the spring in is too big and doesn’t do its job. And the measurements are in millimeters not inches not standard. Other than that the quality is very good, strong besides the bits. I really wished it worked as promoted. Because it didn’t I will be asking for a refund.

Awesome set. Sizes of the holes it gives is awesome. Performs as it should. Cut thru like butter! Sharp and easy to use

Broke blades

Started putting lights in my garage, 6" hole saw nearly broke my wrist from kicking back. This product was manageable and didn't bite like the hole saw. I was able to use a cordless drill rather than corded. Cuts are a little jagged until you figure out the pressure needed, just let it feed itself deeper. Dust collection difference was more than worth the cost.

I had done 4 six inch holes for recessed lighting. Works pretty good. Some holes came out a little jagged, but could be me. Bowl collects about 95% of dust. Overall happy with it for the price. Looks like it could last a while for my homeowner needs. I had a piece of scrap drywall I tested tool on to trial before drilling into my ceiling.
