carbide inserts

Hey all, I have been beating my head against the wall trying to figure out carbide insert nomenclature. I have studied this chart: https://www.carbidedepot.com/formulas-insert-d.htm but it seems that I keep running up against examples where it doesn't fit. I also looked at this chart...

I had some TCMT and CCMT tools lying around, largely unused till now. I tested them on a piece of 1.5" 1045. No real questions here. Just newbie observations. Comments welcome, of course. Using the speed/feed tables, 1045 needs about 800 SFM with carbide. So, at 1.5" - 2100 RPM, which exceeds...

I'm pretty new at this stuff. But I've been happy with the results I've gotten turning 304SS in sizes under an inch. So I felt emboldened So when I found a 4' length of 303 round bar at the local scrap yard... But the larger diameter (even in a more machinable alloy) is not nearly as...

I came across the term "wiper insert" at a Sandvik site, apparently for improved surface finish. Mitsubishi's site shows how the corner radius is modified. http://www.mitsubishicarbide.com/en/technical_information/tec_turning_tools/tec_turning_insert/tec_turning_guide/tec_turning_wiper Anyone...

Continuing my new lathe education: Thought I try boring a deep hole in my sacrificial brass rod. Don't have a boring bar with HSS, but one with carbide insert with those molded-in chip breakers. Thought I'd try it, not expecting great results. First drilled out to 0.5", about 1.75" deep, then...

First let me start by saying I'm new to this and fumbling my way around. I have some 6061T6 bar stock and I'm trying to get a good finish on it with carbide inserts. I'm not sure where to start with spindle speed, power feed rates and insert selection. I have tried various spindle speeds from...

I have a Shares tool & cutter grinder and have sharpened some lathe inserts successfully. (Good enough for me, not back to factory!) It changes the geometry and to some extent the affect of the chip breaker design. The result has been a sharper edge that likely will dull quicker than the eased...

i scanned a carbide insert chart that i keep in my shop reference binder. maybe it may help others out in identifying stray inserts. https://lh6.googleusercontent.com/-OgVM8no9E5g/V-qDBoHAW4I/AAAAAAAAISU/CHW6jb9GVHgAtKZbxtNBXFfjYHiQlMh5gCL0B/w1141-h830-no/Insert+chart.jpg
