I don't drill large holes all that often so hopefully they will stay sharp for a while. My drill bits stop at 1", anything larger I just program a CNC circle. I just ordered the Vevor set and will probably use them instead of S&D bits because in comparison they just cut a lot better and require...

How many of you guys are using trepan tool, instead of annular cutter? I'm guessing they are not inexpensive but replaceable cutters sound like a great solution to avoid sharpening. Anybody try this Vevor set of annular cutters...

I'm out of town this weekend, where exactly is this located? If not too far I can drop by On Tuesday?

Okay, done and I'm impressed, 1.0625" cut like butter (cold rolled steel) 1'' depth I picked one up on sale at PA just to try. I will definitely be picking up a full set when they are on sale again. Way less drama than using large S&D bits.

Annular cutter virgin here.... I see it's recommended to have a spring loaded drive when using an annular cutter, , anyone try this without the spring loaded gizmo. Would the cutter not simply retract and then if the plug is inside the cutter, just tap the pointy pin in to pop the plug after...

I have a few 1" thick blocks with various holes, and they seem to work fine and can be used almost anywhere when the thing being tapped can't be mounted on the mill. It works for me.

Great post, and another great video from C42, I really like his videos. I'm going to give it a try.

Question about using large drill bits in Albrecht type self tightening chucks. I do most of my large drill bit drilling with my drill press and it has a Jacobs chuck. For the mill I have a clone of the Albrecht chuck and I have read as well as experienced the over tightening that can occur when...

Comment from the peanut gallery (true hobbyist;-)) , those dime a dozen type AliExpress carbide inserts work really well, my hunch is the smaller your lathe, the more they help. I almost never use HSS anymore. Beyond grinding a tool for a specific specialized task, I wonder if this grind your...

Thanks for the link, I actually watched that one a while back, a couple of interesting points: 1) the gas struts, I'm hoping to avoid that by using a servo with an integrated brake, basically the servo is locked up mechanically whenever it's not being commanded to move, that includes with no...

I'm now thinking about how I'm going to add CNC capability to the knee joint of my A1S mill. I want to use a similar 2.4Nm continuous torque 7.2Nm peak ac servo, except this one has an integrated brake. I have a beefy double nut ballscrew waiting in the corner. From my measurements and reading...

Completely agree, to really appreciate what is going on with the uC, writing some actual machine code at some point is really worthwhile, I programmed my third robot all in assembly code. I have a decent amount of experience with C, I'm not a fan of C++ either, I have never used C#, what do...

I just used the online version (no password required), might be handy to have a standalone version.

A quick google search led to this online version.... https://www.intuwiz.com/circle.html Testing now seems to work great.....

I'm as "hobby machinist" as it gets. I have yet to see one and the name and shape implied (to me) that is was for checking the squareness of a bored cylinder. I surrender.
