Step 3: Different Types of Tools (Cont.)

Indexable carbide tooling is the third type of tooling for lathes. Indexable tooling uses steel tools, with a screw or clamp securing a carbide insert to the end of the tool. Indexable carbide tools and inserts are widely available, as they are almost unanimously used in CNC Turning. Indexable tools and inserts come in many different varieties, one can be found for almost any job. Unlike HSS or brazed carbide, carbide inserts require no sharpening prior to use. Most inserts have at least 2 separate cutting edges, and can be rotated when one edge dulls. Indexable carbide tooling as does not typically re-adjustment of the tool height when swapping inserts.

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.
<p>I was really hoping to find something about tool to use for facing and which tool to use for turning?</p><p>But your instructable has other good information. Thanks</p>
<p>Nice instructable. thks.</p>
<p>I have an older smithy 1220 and want to upgrade my tool holder. there is a dizzying array of manufacturers, brands and sizes out there. How do I find out what aftermarket tool holder size is right for my lathe? </p><p>At first I wanted to try and save money by making my own, but it looks a bit daunting for someone (me) who is just starting out in this hobby and doesn't have all the tooling needed to do the job. </p>
Trouble with indexable carbide on amateur lathes is usually a lack of stiffness in the machine, leads to tool chatter, and tool chatter leads to edge failure very quickly. <br> <br>Don't mess around with tool height adjustments like that, beg/borrow/steal a decent vernier or digital height gauge. Measure the centre of your machine relative to the cross slide, and set your tools off that.
Thanks a lot, I really appreciate the discussion of the different types of tools. I opened up the Techshop cabinet for my first independent lathe session and was quite puzzled at the variety. I plan to get some of my own, and this was a good place to start.
A nice clear explanation. Thanks. I've not got a lathe (yet) but found this interesting.
This is a very thorough first post, thank you so much for the share. Your steps make lathing a much less daunting tool to use.
