If you are looking for a really good quality bit set, remember you get what you pay for!  That is especially true of drill bits.  If you search amazon you will see a ton of drill bit indexes so how do you know which is a good one?  One line that I can vouch for is Norseman.  They also produce Viking drill bit sets and indexes.   The bits are made in the USA, in my home state of MN.  I have been selling tools and fasteners to the trades for 25 plus years and have moved a bunch of bits.  Believe me, they let us know fi something isn’t up to their standards.  Norseman has always been our choice for quality drill bits and indexes.

My favorite bits are the Norseman Type 190AG bits.  These are what Norseman calls their super premium black and gold bit.   These are simply an excellent bit that holds up well and features a 135 degree split point that keeps the bit from wandering at start up.  The type 190AG series is what is considered a jobbers length bit which is most common.  Shorter versions of the bit are also available.

There are a few different bit sets or indexes available.  You will find a 21 piece that ranges in sizes from 1/16” to 3/8” by 64ths.  This set is in a metal index.  The 29 piece set goes from 1/16” to ½” by 64ths.  This set is available in a metal index or in a plastic index.  To me the plastic index is the only way to go.  Unlike the metal indexes, the bits are easy to slide in and out and the index never rusts or dents.    It also seals up tight to keep moisture out of the set.

You can find cheaper bits online but you are looking for the best quality bits or you likely wouldn’t be here reading this post!  I embedded a video below showing the Norseman Type 190AG bit drilling through a grade 8 bolt.  Now this may not be your typical application but you get the point.  One word of caution when searching on Amazon for Norseman bit sets.  You will see sponsored ads that pop up with showing very similar bits.  If you want a quality drill bit set, stick to the Norseman and Viking drill bit indexes.
