They are good but you have to pour water on them when using for them not to rub out/ get dull. You can get it but its not for heavy duty for long

    • I've used my set quite frequently for a year now, and it's held up perfectly so far.
Style: New Style - 5PCS(1/8" to 1-3/8")
I'm always shocked at how expensive step drill bits are, considering this whole set costs about a third as much as a single step bit elsewhere. I bought this set because of the night and day difference I've found when it comes to drilling steel with cobalt bits versus plain HSS. I honestly haven't been disappointed in the quality of this set as far as drilling goes, which is the most important thing by far. The bits cut quickly and cleanly and don't appear to have dulled in over a year of use. There are a few downsides, but I consider them worth it for the price. First, the size markings inscribed on the bits are of varying quality. Some are more difficult to read than others, and they don't always line up with the steps, meaning I occasionally have to count down from the top to tell which marking goes with each step. Also, the case is in no way aluminum. It's part plastic, part imitation-plastic, but with a metal latch and hinges. It's actually a very nice case in spite of the materials, just don't expect it to take a lot of abuse. ... show more
