I need to purchase a set of brad point bits (all I own are split point). I see some that are High Speed Steel (HSS) and others made of Chrome Vanadium (Cr-V), and I'm not sure how much the steel should factor into my purchasing decision.
I know it's not just a matter of "cheap ones are HSS and expensive ones are Cr-V" (or vice-versa) - I see that a highly rated brand has individuals and sets in both materials and the prices are similar for similar sized bits.
I did find this handy description but it focuses on drilling in metals, not wood, and is, therefore, off topic here. I'm sure some of it translates to wood working, but I'm not sure exactly how. At this link, they state:
High-Speed Steel (HSS) is a popular material good for drilling into soft steels as well as wood and plastic. It’s an economical solution for most maintenance drilling applications.
However, they have nothing to say about Cr-V, so I don't know if Cr-V, while apparently a popular material for wood-boring bits, is considered a more or a less economical choice, and whether it's better suited for wood drilling than HSS
I'd imagine that one is better for some purposes, while the other is better for other purposes.
- What are the advantages of each material and when would one prefer one material over the other?
- Is there enough difference to have sets of both (at some point down the line) and make a selection based on the type of hole/material one is making?
- Is there enough differentiation between the two materials to really factor it into the decision making?
