Requires a good 5//8 " drill bit capable of cutting through
The drill bit worked great but I thought the $40 price was a bit over the top just because it had a 3/8 shank to fit the smaller drill bits. Larger 1/2 shank drill bits were a lot Cheaper #2: Area hardware stores only sell bits with 5/8" 1/2" shank.
Pros
Multipurpose tag metal Cobalt steel tools are similar to HSS but have a higher cobalt content to improve performance when cutting harder metals such as stainless steel or nickel alloys.
