*by A***R on 7 January 2026*

I bought these drill bits in 1/8 1/4 and 6.5mm for drilling out stainless steel rivets. They worked very well. Drill at slow speed for best results on SS. The 1/8 size, extra care is needed as they are small and break if to much pressure is used Never broke any of the larger sizes
