CUSTOMER REVIEW If you work with light gauge metal, especially subpanels in electrical boxes, you will fall over in amazement after using these.
The typical subpanel in the back of an electrical enclosure is the ideal application. I don't recommend pushing it beyond that thickness. These are expensive and will break easily in the wrong application.
The drill on a lower speed setting is recommended. Higher speeds might work on lighter gauge panels, but result in a higher risk of breaking a bit.
These are the best friend of the electrical panel builder, or industrial maintenance electrician who needs to mount devices in electrical panels. The time they save and the clean work they result in will make you a hero.
The quick change bit holder is a nice bonus. Many panels need multiple sized tapped holes in them.
Use them right and you will sing their praises. Use them wrong and you will be upset.
