Carbide Toolholder advice
I am currently using a rather old SECO 20mm insert holder (MCLNR) with CNMG110308 inserts. I have found this to work quite well in my lathe. The problem is that the inserts are hard to get. I can buy them from General Tools in Adelaide, but have not had any success on EBay. I am wondering whether it would be a good idea to change to a more common type. CNMG searches come up with lots of name brand inserts at good prices for CNMG3xx which are only slightly bigger than my current ones.
My question is should I change to this size holder / insert or is there a better type of insert to use. The 80 deg inserts seem to be popular for straight cutting.

Hi Dean,
The trigon WNMG inserts offer better value for money as you get 6 corners instead of the 4 you get with the CNMG. TNMG is the same but i don't like the approach angle as much. The WNMG holder is MWLNR/L.

Thanks Ueee.

I run 20mm tools and WNMG0804XX inserts...
I got my holders from CTC tools.. They were good quality..Light red, the colour of choice for the discerning man.

Thanks .RC. Originally Posted by .RC.

Sigh.
