A few weeks ago I got some used micro boring bars. With them it's possible to make holes without drilling before. In this video I make a mount for the micro boring bars and test it.
The tool looks like a typical mini boring bar from ph HORN. I admire the willingness to make your own frames, although they are available in several sizes. From an economic point of view, making a hole in this way is a big waste of time, especially when you need to make a deeper hole, in a harder material and in addition in a series of, for example, 1000 parts, but the idea itself is very positive in terms of a DIY enthusiast.
I bought a similar second hand set from Bengs. I think the brand is Paul Horn. A new set is very expensive! They work wonderfully, but I got serious chatter on tin bronze which is rather hard and brittle. These tools are normally used with internal cooling in CNC machines, behind a screen. Be careful not to crash them. Flying carbide fragments can penetrate the body. They need some sharpening on a diamond wheel after a while. Maybe I will build a simple tool grinder.
Thank you very much for the good tips! I have a Diamond wheel for a dremel engraver which i use for the sharpening of tungsten electrodes. I will try this if it becomes necessary.
I love this format of video no bullhit just straight up good machining work and its kinda like an ASMR for dudes that love shop work like myself lol great video!

Je kan inderdaad in veel gevallen met een Boorbaar een gat maken zonder voor te boren. met een 12 mm Iscar boorbaar met wisselplaatjes gaat het ook.. Je hebt deze boorbaartjes gekregen schreef je, er bestaan er ook met gewoon een Cilindrische schacht, dus volstaat in dat geval een gaatje boren en daarna ruimen voor een goede passing, en dat zal een stuk stabieler zijn dan dit gat, de achterkant van deze boorbaartjes heeft een schuine kant, die kun je gewoon af laten steunen op een klein Paspennetje dat je dwars door je houder perst, en dan heb je meteen een diepteaanslag Als je een slijpmachine met Diamantschijf hebt, kun je ze ook zonder al te veel moeite zelf slijpen uit versleten of gebroken freesjes van VolHardmetaal, werkt perfect, ik maak zelf ook zo mijn boorbaartjes, en gebruik ze in Titanium
I use these tiny boring tools on my micro lathes, they're excellent! I prefer the Sandvik and Iscar branded ones because they have an ordinary round shank which makes things much easier. 👍
I'm not sure if it's a problem or advantage to have round shank boring bars? Sometimes you want to change top angle so you can rotate them in holder but other times they can be a pain to get 'dead level'
I did this on accident a couple of years ago on a citizen swiss lathe. The drill broke on a copper job and the ph horn boring bar kept making holes. I couldnt believe it.
Neat tool holder but are the mini indexed boring bars cheaper than a drill of same size? I like what you made and could possibly have a use for it but I think I'll stick with conventional drill bits and boring bars
No, the advantage is that you can make very precise holes with any (small) diameter, but i also would suggest to drill before, so the boring bar works much smoother
@@randomtechnician I use these type of carbide bars when making bush bearings for model engines. You can get them right down to 3mm diameter which makes it easy to bore precise bronze main bush bearings dead on size.
Buf!! la precisión brilla por su ausencia!!, la herramienta te canta como una campana a pesar de ponerle una chapa, teniendo comparador, has metido el latón a las bravas, además no veo el motivo de castigar a la herramienta sin un taladro previo, en mi taller no te contrataba con esas referencias, aunque yo me dedico a la industria del molde y es muy exigente
@@randomtechnician Me too was a trained toolmaker in the 80s then we used Deckel and Aciera mill. Then wanted to get an Emco lathe for hobby but way beyond my means :(
It's called measuring gauge or marking ruler with flat slide(Streichmaß in germany) i use this one: www.contorion.de/p/holex-streichmass-mit-flachem-schieber-c85173285?q=streichmaß&$ps=1
Why the 2nd angle at 9:20 is 30 degree? The mini bar angle is 40 degree (at 7:52) , and you set the 1st angle is 20 degree (at 8:44), then the 2nd should be 20 degree. What am I missing?

Love the video--no music or hoopla--very relaxing.
I've used mini bars like these for years at my work, but never thought to try one without drilling a hole first. Well done, Sir!
Thank you!

I can't help it but wounder if boring via the tailstock gives better precision. At least on a mini-lathe where cross-slide is so unstable, or........

Hello where do you buy thèse tiny tools? Greetings
www.bengs-modellbau.de/werkzeug/werkzeuge/mini-bohrstangen-zum-innendrehen?number=3692
Why the 2nd angle at 9:20 is 30 degree? The mini bar angle is 40 degree (at 7:52) , and you set the 1st angle is 20 degree (at 8:44), then the 2nd should be 20 degree. What am I missing?
It's the other side of the vise-scale, 50 degree is zero here, so 30 is -20 degree.

что за перевод? Наверное должно быть "Мини токарный станок - сверление БЕЗ СВЕРЛА"
Точно

Расточка это не сверление.

И что я посмотрел ? И для чего ?
Расточные оправки для выполнения точных отверстий любого диаметра
Бронза то клас,а сталь так слабо ? Покажи.
