    • As these bits are not like a drill bit when cutting thicker steel the hole is larger at the top than the bottom

    • At least it keeps all the bits in one easy to find place, provided you put them back in it!
    • I absolutely recommend these bits.
    • Long story short, even with copious amounts of cutting fluid, my drill press set to the lowest setting, and backing out the bit after every half second of cutting, the bits I received failed before I was able to widen a hole in a basic (unhardened) washer from about 3/8" to 3cm

    • Good bits for the price.
