[@ianmcdonald7368]

I love this whole machining towards the tailstock thing. Your results are impressive. Subscribed!

[@userwl2850]

Thanks Ian.

[@drubradley8821]

Turning something that can hit and that damn long, with something even damn longer, would scare the sh*t out of me, lol... Boss, you have my respect !!!! This was an easy subscribe, after watching some of your other videos, and... I in that couple of videos, even learned several things, thank you... The crazy part of this???? Is that this is just another day for you at work, lol, freaking crazy!!

[@cumminsscout]

Thank you George.

Hi David, Great videos, really impressive tools. What’s the reason for offsetting the cartridges? And how do you know how much to offset them by? Cheers, Matthew

NOW THAT IS ONE EPIC COOL TOOL !!

Hello again.. so what material are you using in those tube for your drills.. lets say 355 steel wraps up like a christmas ornament under load.. 4340 didnt play nice either.. :P

[@MakinSumthinFromNuthin]

F me....You do the most impressive work on youtube Userwl. Do you even own a chuck that will hold a 1" bar of steel ?..LOL Thanks for subscribing to my channel

[@userwl2850]

Where are you Richard. Hope you are well and ok buddy.

[@MakinSumthinFromNuthin]

Hi David, I am well & OK. Still dealing with the legal issues as it pertains to my land....beginning to to see light at the end of the tunnel. Thanks for thinking about me my friend, I do watch your videos and hope you are well and safe~ Richard

@@MakinSumthinFromNuthin Richard, do you know David's status? He hasn't passed away has he?

[@pmi0394]

What is the wall thickness at the Thinnest points. What is the offset of the inner tool in relationship to the bore?

[@Moronicsmurf]

May i ask what are the insert geometry you using for the cartridges on these drills? Are they drill specific like spade bits?? i was thinking they are WNMG or CNMG inserts or similar more normal lathe bits with a custom holder...

[@userwl2850]

They are WCMX 06T308 INSERTS used on all Trepanning tòols regardless of diameter. 👍

[@Moronicsmurf]

@@userwl2850 thank you very much for answer. :) So in essence its a drill specfic insert, i guess there is no real holder for them then that one can can go get and cut off one would need todo it like you do and mill out your own??

[@userwl2850]

@@Moronicsmurf they are also used in u drills. WNMG are usually used in turning tools. Much stronger with negative clearance but must be positive for drilling and Trepanning. Hope this helps.

[@Moronicsmurf]

@@userwl2850 it does for sure.. Been watching your videos, and also found that finnish guy using it in a CNC.. so got the idea i should be able to run one in my Okuma LB-15 for making spindle housings. :)

[@user-zt1cf6nb2v]

Hi. What is the ISO designation of tool holder and inserts? Thanks.

[@userwl2850]

I sell the insert cartridges. Sandvik copy. Inserts are WCMX 06t308.

[@user-zt1cf6nb2v]

@@userwl2850 ok. I find, that the designation of tool holder are R430.26-1114-06 and L430.26-1117-06. Right?

[@jjs4x]

What material do you use for those, pre hardened 4130?

[@userwl2850]

jjs4x I make all tools from EN24T

How can i get cartridge tool for insert?

[@userwl2850]

I sell them.

[@catabaticanabatic3800]

Are the inserts offset fore and aft?

[@userwl2850]

Yes... depending on tool size.

[@snehalshaileshpatil4200]

Halo I like trepanning tool

[@snehalshaileshpatil4200]

I want to make trepanning tool

[@meocats]

where did you get the tool cartridges to hold the inserts?

[@userwl2850]

meocats hello. i make them. tooltekprecision.co.uk

[@meocats]

nice. i'm just a hobbyist. how do you make a BTA drill head?

[@oh8wingman]

The video is entitled step by step guide to make a trepanning tool. SO when did that happen because I certainly never saw it. Change the title otherwise this is just so much clickbait.

[@1dgrdgr]

Now I can explain it but I can't understand it for you. Make a tube. Machine chip clearance on the sides. Machine pockets for trepanning cartridges. Mount it in your lathe and shove it in the end of your stock. Or maybe just watch the video again.

[@chrishill6276]

What a waste of time and material

[@1dgrdgr]

Can you imagine this guy built a career on wasting time and material like this?
