I was trying to remove an over the fridge cabinet today and was having trouble.
The screws into the face frame of the adjoining panels stripped as I was trying to get them out. I know - my fault for using a drill driver. . . .
Anyway - I ran to the Orange Borg and bought the Alden Pro Grabit set.
It has 3 sizes of extractors.
You ream out the screw with 1 side of the extractor and then flip the extractor and it grabs the newly reamed hole. 10 minutes and all 6 stubborn screws were gone.
Well worth the $20.00 I paid for the set of 3 - priceless actually . . . .
