Nice touch, & nice timing with the Tommy Boy clip. It definitely evokes the correct mental image. 👍🏾 These machines (especially CNC) can only be as capable as the machinist operating them is competent. Pretty sure we've all either heard the horror stories, or lived the nightmare of, for instance, having just spent hours indicating and fixturing a job, and leaving the floor just to get some air, or find a certain tool, (or your resolve was waning at suppressing your impulse to dismantle a particular colleague). The moment you were out of earshot, the FNG (who may or may not be bossman's relative) sauntered up to your workspace, hit the big green button on that machine you sank your whole day on, and then said *"Time for a smoke break!"* as the machine ripped itself into shrapnel. [I know this anecdote sounds highly specific, but you'd be surprised & amazed at how many people I've heard articulate _exactly this story_ almost verbatim] 🤡
Thank you so much for taking the time to make these educational videos. If I may I would like to see a video about efficient and different ways of centering various tools in a lathe. Thanks
I don’t know if I missed it but at 28:33 those style of carbide drills have a 4 point contact system unlike the Normal 2 on a drill, you see that line slightly raised, it’s there for double the stab ability in deep drilling
Sorry for multiple comments, but chrome doesn't let me edit on the tablet...nice presentation, lots of good stuff...i wanted to note that, with solid carbide, any misalignment that can cause "wobble" can also wuickly break a brittle carbide drill!
I always wondered how they drill a long rifle barrel and keep it straight. Still don't know ;-) I would think a larger caliber would be less troublesome but how about .22 ?
Collets..... how I love my collets, we have ER16 holder with 30mm shank and second with 25mm shank (having 30mm bore in T12 and 25mm bore in T8 is a bit of a pain tho), two ER32 holders for CNC lathes I use, they´re really great is used properly... We´re using plain old HSS twist drills for everything under 16mm, if you can, get solid carbide drills for holes you´re going to thread, they´d save you plenty of time... Drilling 16mm hole 100mm deep into 304 stainless is pain in the butt, get TiN coated drills for stainless at least U-drills (inserted drills) are lovely, we´re making G2"-11 threaded nozzles for oil tanks out of C45 steel, well, 40mm U-drill, 650RPMs, F0.12mm/rev, 60mm deep, you blink and it´s drilled... X-8, you have 48mm bore, X-16, 56mm bore... just slowing down the RPMs a bit and feeding harder so it won´t chatter that much, biggest b..oring bar I´ve got, bore it to 57.1mm and thread it, done... Just make sure to add a note to program so you will always set up the drill with outer insert facing the right way.. +don´t you dare peck with inserted drills, just plow it to final depth For drilling and even making shallow holes in plastic (we´re using this method in PVC), use good ol´HSS two fluters.... Using 14mm two flute endmill drill a little shalower than finished bore, ooop, bore it in X axis, finish it with boring bar.... Lock the endmill into collet so one flute will be on center by eye so it´ll actually cut... Great video for beginners :)
What about core drills? ( three fluted drills ) ive got a big one but their super good if you have an existing hole and want make it 80% bigger but ive rarely seen them tho i guess thats was boring them out is for i guess.
Hi, thanks for a very informative video. Very original content too. Please try and get your focus setup sorted - I realize you are aware of the problem, but it really ruins your hard work - especially when you are pointing out fine details.
Thanks for the feedback Steve! This camera is stunning footage wise, but the auto focus can be troublesome. I will have to figure out a manual override for videos like this.
Are you even aware how many years of professional skill.and knowledge you just shared in 30 minutes? You increased my knowledge more in 30 minutes than i would probably have ever learnt otherwise.
Just buy ghurig drills... dont pilot or spot drill. Just use a better machine and better tooling and save like 15 minutes of machine time eliminating thousands of unnecessary tool changes. Ghurig or ghuring im not german
Best drilling video I've seen, thank you.
Nice touch, & nice timing with the Tommy Boy clip. It definitely evokes the correct mental image. 👍🏾

This video is not boring, its drilling :P

Hope they help, centering tools would be a good video. Thanks for watching!
Ya man, people in the trades hold onto information , education from outside sources are important.
fantastic information .....thank you so much......cheers from Florida .....Paul

On that deep drill...does lubricant, in quantity, help get chips further up the flutes, reducing the amount of "pecking" needed?

I haven't seen yet in depth... Alignment the turret.. please make one..

The annular drills are meant for through-holes, correct, where they significantly reduce the amount of material being chewed out of the work piece...

For aluminum. Idk why
thank you , very interesting video! nice job

Don’t give up on videos bro
It’s a centre drill not a spot drill ?
Are you even aware how many years of professional skill.and knowledge you just shared in 30 minutes?
You increased my knowledge more in 30 minutes than i would probably have ever learnt otherwise.
Do you realize that you're saying "focus" aloud every time you want it to focus? :)
Cs or 6s ❤
Collets are non negotiable

Guhring aren’t bad drills but they are no where near the best, Walter, OSG, kennametal, sandvik, make the best👍
please don't use the phrase "you can actually" it's condescending
I think your comment is condescending
@@PillePalle30 It is how do you like it
Well you see, noone is condescending, actually
