HAM RADIO GO BOX BUILDER TIP - CARBIDE TIPPED HOLE CUTTER

When building Ham radio go box, many challenging things happen. Making a large hole on a hard steel panel is one of those. I was not successful with step drill on my previous attempt, which ended up grinding with Dremel tool. This time I used Carbide tipped hole cutter and it worked real good, so I'm sharing my experience with my fellow ham friends. Thanks and 73
