Review on MKC 20PCS 2 Inch (50Mm) Silver Desk Wire Cord Cable Grommets Hole Cover With Hole Saw Kit High-Speed Bi-Metal Holesaw Drill Bits For Office PC Desk Cable Cord Organizer by Michael Hughes

This is a great complete set and even at this price point a fantastic deal for someone like me who uses them for home projects rather than professional use. I used it slowly and carefully, I had no problems. I don't have to drill holes often, but it's good to have it in so many sizes when I need it. nice case to keep everything together.
