  • Not sharp enough
Style: 1/8-3/4''
I have use much sharper tools than these.. I'm not sure if it is the quality of the metal that they are made of, or it is that they are not fabricated to be sharp as knife like some others

  • Not worth it bud.

  • Trash
Style: 1/8-3/4''
Threw them in the trash after trying to use them twice in some thin 18 gauge steel. They are so dull that even after drilling a pilot hole they can't step up the hole size. I have a set from harbor freight that I thought were poor quality, but they have these blown out of the water even after I've been using them about 2x per week for 2 years. Go buy the ones from harbor freight if you want to save some money. ... show more

  • This was exactly what I needed for a great price
Style: 1/8-3/4''
I needed a stepper bit, but just for occasional use. These were perfect. Cheap enough, effective enough.
