Gotta give props to Horn for making a boring bar this small! This video was a pretty big challenge to make so I really hope y’all enjoy!

whenever i go to work and grab a .375 flat grooving insert, check it with my calipers and it hits perfect like it does every day; it makes me feel like a deep respect for the people that make the precise tools we use to make precise parts

[halfhappy]

We ordered our perfect zero kit with our next swiss machine, should be here next month! It will be a game changer for our micro stuff!

Going super small is always 100x harder than going super big. I couldn't imagine having to use such small and delicate tooling.

As in all your videos . . . . gotta stay to the end! Nice job Donnie and the videography never ceases to amaze me.

[Will-No-Co]

Ok. That’s great, but who’s the mad scientist that made the boring bar? That’s insane.👍

[stevieg]

What amazes me is watching a channel like wristwatch revival and being astounded in the level of precision of these Swiss movements like Rolex and Omega that were made in the 1950s before CNC was ever dreamt about, that to me shows the talent those people had

[JimmyLuffjr]

When you check the RA of the bore I will really be impressed.

[AvallonYo]

They managed to make a boring bar interesting.

[RTM]

It’s amazing, but watching true watch makers make screws by hand is on another level.

[paulkraus]

After seeing this part in person, I can really appreciate how small this part really is .
Also love Bro ‘s shirt

[markdavis]

Great video Donnie! Crazy tools Horn makes!

[Scott-weeks]

You guys are the best. I want to know how to manufacture that part pictured 😊

[TylerBrigham]

This made me glad that other people make small stuff. I make a little .08” cone every once in a while and I want nothing to do with a .008” boring bar. That camera alignment system is cool. I’m going to check it out

[atramentius]

currently using 0.25mm boring tool for a part out of Titanium to machine a 0.4mm hole. Gladly did't destroy anything yet

[Zsycho]

I once had to drill a part with a 0, 7mm x 30mm drill. I was shaking just unpacking the damn things and the drill operation took forever.

[JesseGonzalezFishing]

Saw this running at the BOOMBASTIC Open House. Pretty crazy

[ChuckMcFarlin]

PH Horn was my go to for small tools that always worked great. I never had to go that small though,

[crazycooterMN]

I have a customer gearing up to drill some .0007 holes. They're trying to drill through .015 thick material, gonna be the craziest thing you can't see! $24, 000 nsk spindle going to 80, 000 rpms and NS tool made the drills @ $400/pc. Trying to get 80-100 holes per drill. They look like bee stingers!

[dominic]

Always preferred making small stuff. Even though the larger stuff is in someways trickier
