Step 3: Different types of tools (Cont.)
The primary drawback of indexable carbide tools is the initial cost. Most common tools start around 30$ for import tools, and can run up to 200$ for high performance on brand tools. The inserts themselves are typically around 5$-10$ depending on geometry and grade. Additionally, if you need a special tool, you must buy an additional tool, rather than grind it yourself. However, if you don't like grinding your own tools, and just want to make a lot of parts, indexable carbide is my favorite way to go. The inserts cut very well in a wide range of materials, and require little to no time after setting the height once.
