I really need a drill sharpener. I bought these to get through a project that I thought would use at least half of them, but one bit did it all and is still quite sharp. Need to get more of these in different sizes.

Long lasting high speed drill bits that enabled me to drill out an 8mm metric class 10.9 hardened bolt seized in an aluminum casting.

The only drill bit to use for stainless steel drilling, works great still using the first bit.

Have to make a addition to my first review. The product cuts fast and clean at first abut after about 5 uses it goes dull and needs to be replaced

Handy to be able to purchase a quantity of a size I manage to break pretty often. They seem to be about as good in my usage as any others I've used. I tend to lose them or break them before they get dull enough to worry about. .
