Dust Bowl for Hole Saws

A:  The product is made to use with hole saws and not drill bits alone.

A:  Hi Greg, I had the same concern, it’s actually clear. I purchased 2 of these as I was installing well over 30 can lights. They worked perfectly, and yes you can see through these to align your hole saw. 

A:  Dear Valued Home Depot Customer, We have reached out to the manufacturer and their answer is,There needs to be a flat surface to best utilize the bowl. Such as a flat ceiling.

A:  My recommendation: After installing the hole saw on the mandrel, run its arbor shaft through the hole in the dust bowl, and through a half inch washer before inserting the arbor shaft in your cordless screw driver. Leave room between the cordless driver, washer and dust bowl - so that they are not tightly against each other. I went up on a ladder, held the dust bowl against the soffit/ceiling, pressed up on the bowl till the pilot bit engaged the center of the hole I wanted to drill and pulled the trigger.

A:  Press the flexible rubber dust bowl to surface and compress until hole saw hits surface. Drill your hole all dust is captured in bowl
