Index holds 36 taps and drill bits in tap sizes #6-40 to 1/2"-20 (NF) and #6-32 to 1/2"-13 (NC) and drill bit sizes #33 to 29/64" (NF) and #36 to 27/64" (NC). Labeled storage holes for identification and organization. Made of steel with an epoxy finish and has a snap-lock cover for durability and protection. Made in USA.
As a result of my tests, I determined that this product from the Industrial and Scientific sector was a big letdown. The bits were inconsistent and broke easily when attempting to drill through metal. The one positive aspect is that the set includes a wide variety of sizes. Overall, I would not recommend this product as it is not reliable for industrial use.
This is a nice steel box that I wanted. It is NOT designed to hold all of my drill bits. I don't like having holes to store drill bits of a certain size. Who knows how to read sizes!
Quality construction, should be very durable and should last for years. This case allowed me to get rid of my "box" of taps and associated bits, allowing me to quickly select the correct tap and identify the correct tap.
