Easily make a flow drill

a look at making a flow drill to drill very very hard metal let’s drill with the homemade Flow-Drill
#flowdrill #frictiondrill I mean how hard is it to make a flow drill at home in the workshop let’s find out if you can indeed make a good flow drill for drilling I think you can and let me know if you have any questions about the homemade flow drill

Awesome...

[@TheKnacklersWorkshop]

Hi Chris, That was good fun... I did not think it would work... Well done... Take care Paul,,

[@Battery-cat]

Have faith in the bodge man ! 😅

[@chrisstephens6673]

Maybe less pointy so you have a greater area to cause friction and therefore heat. A point contact like yours is almost like a bearing with little heating effect to start with..

[@graemewhite5029]

We used to drill out hardened bolts and dowels using Stellite rods. Grind a shallow 3 sided pyramid on the tip and away you go. Needs a rigid setup mind.

[@Battery-cat]

Thank you 👍 sounds a tough job to do getting a hardened bolt out !

[@MG-Driver]

Chris, SNAP! I’ve the same bench grinder!

[@Battery-cat]

Not a bad little machine, I got it second hand years ago

[@matsworld9386]

holy smokes .. I definitely thought this was going to end in disaster .. way to go and kudos for just "trying" .. unreal really ..

[@Battery-cat]

Learn by “doing” 👍 it’s the only way 🙂

[@matsworld9386]

@@Battery-cat Without a doubt .. I aplaude you trying to ram a pointy bit of steel through a blunt piece of steel .. in my mind there would've had to be some kind of a cutting edge somewhere .. hence my bafflement ;) keep the vids coming, really enjoy your channel :) plus, I have the same lathe .. it's really what brought me here ;)

[@WideVisionMetalFab]

I've seen flow drilling before, but I wasn't sure if it worked on hardened steel. Now I know!

[@Battery-cat]

It’s a interesting phenomenon for sure and fun to !

When I worked as a tool & die maker I used carbide burrs to remove broken taps.

[@LucasMarques-im8pw]

No

Sent by Ben, tool Addict, amazing stuff Chris, subscribed, will check back thru your other vids slowly!

[@jimbotron70]

What did they use before flow drill?

[@Battery-cat]

That’s a good question, I’m guessing they just took their time with lots of oil 🙂

[@codprawn]

I thought you were mad trying this - but it worked. Friction stir welding next?

[@Battery-cat]

Always trust the bodge man to get the job done ...

[@DolezalPetr]

to make it work better grind the pointy end a bit oval shaped, so it has kind of two half flat sides so it can push the material better

[@manfacilitymetalworks1296]

Wow! You need to try it on hacksaw blades now 😉

[@Battery-cat]

Worth a try definitely 🙂

[@tooladdict7463]

I had no idea you could do that very clever Chris PS have you still got the train set an a lot I just watch one of your old videos very cool :-)

[@bigblue1402]

You really need to make a visit sometime Chris. Especially if your gonna grind carbide. (I must say it did look like a tig tip on steroids when ground)

[@Battery-cat]

Thank you , carbide was tough on the grinder!

[@nexusrnah6418]

I've heard tungsten carbide dust is dangerous for lungs

[@MaturePatriot]

AvE demonstrated this a couple years ago. I had to quit watching him because of his language. Very nice Demonstration. I hope you wear a dust mask when you grind carbide. "Extensive studies on genotoxicity and mutagenicity have been conducted after a series of epidemiologic studies showed that hard-metal workers exposed to airborne WC and Co dust in occupational settings have increased mortality from lung cancer" (Moulin et al. 1998).

[@joejoejoejoejoejoe4391]

Thanks for the " tip " on grinding carbide, you learn something new every day.

[@JAKOB1977]

"focus your fcuk" on the topic in AvE video and not the language. "I like lesbians they eat at the same table I do" Best regards AvE

[@ppilje]

Man, look for a Russian drill bit. They're marked "no need to sharpening". They goes through glass, metal, wood...one drill bit for all.

[@jacksshed2450]

Christ!

[@Battery-cat]

Welcome to bodge land 🙂👍

[@jacksshed2450]

@@Battery-cat I've gone down the rabbit hole now haha

[@Wobblybob2004]

I'd have just used a tile drill. :-)

[@Battery-cat]

Good idea 💡!

[@alexlo7708]

But the real thermal bit did not go red hot.

[@hinz1]

Whats the point of that? Good rigid machine with helical milling operation and hard milling cutters makes a hole in hardened steel as well, only a bit nicer.

[@Battery-cat]

Cheap ... 🙂👍 and it’s not for anything important 🙂
