Step 2: Different types of tooling (Cont.)

Picture of Different types of tooling (Cont.)
Brazed carbide tooling would be considered the next step from the basic HSS tooling. These tools feature a steel body, with a carbide tip brazed onto the end. While these tools are quite common (Most techshop lathe tools are brazed carbide), I have never had good success with them. From my experience, they are difficult to get good finishes with, and are require a green wheel to sharpen.

Brazed carbide toolbits can be similar in cost to regular HSS toolbits, or three to four times more expensive. While I don't recommend it, if you do want to go with brazed carbide toolbits, you can see extended tool life over HSS, especially in hard materials.
