Anyone know of any way to identify a blade simply by looking at it to see its intended use?

 

[DangerMouse]

yes...simply by looking at it.... usually works for me, what exactly are you referring to?
steel-vs.-wood-vs.concrete drill bits, or what?
plywood-vs.-crosscut-vs.-ripping blades?

saw blades are used for different tasks based on the number of teeth and the angle they are set. Very easy to tell which is for what purpose when you know how they cut.

How to identify drill bit or blade

What i meant is how do you thre material it is meant for by looking at it?

bits for concrete often have a carbide "chip" in the end, this chip or chips is the widest part of the bit, and the flutes have a hi-low pattern, like a tapcon screw. wood bits often have a tight spiral on the very tip, and a wide flute pattern that starts tight and gets wider. steel bits usually have a split tip, with a consistent flute from end to end.

these are general guidelines, but there are many exceptions. it is easy to figure out as you get used to it

the basic guideline for sawblades is the more teeth per inch, the harder the material it is meant for.
think of the coarse teeth on a hand crosscut saw meant for wood, versus the hundreds of fine little teeth on a hacksaw blade used on steel. Plenty of exceptions, but this is a good rule to start with
