    Through stainless like butter!
    I had a flush mount 3/8" stainless through bolt that galled before tightening fully. It was in a location on a jeep where I could not use heat.These bits cut through the stainless (THE A2-70) bolt nicely. Go nice and slow. Don't force the bit, it will do the work. Step up in small sizes and use lots of lubricant. Like butter!The bits are still nice and sharp. No broken bits. Good value for the money. I look forward to having these for a long time.
