How to lengthen a drill bit

[@skbakanov]

You know, if you lay them both into an angle iron they line up just perfectly

[@hardcase1659]

If they are the same diameter.

[@vanboschmichael]

Will the welding not warp the bit in any case?

[@tfit402]

Exactly what I was thinking. But I would have made a couple of tack welds, then out of the angle iron weld it completely, then grind the weld smooth. Should be lots stronger, and faster to do than his job.

[@salesgomez252]

I did something like this to drill through a 10 foot section of wall with a piece of bar. Afterwards I welded two threaded rods to the end and tightened the wall up to secure it

[@Bereft777]

With all of that grinding you could have made two drill bits on a blank piece of steel.

Jeff Garinger very very good

🙏🙏🙏 ❓❔❓❔❓❔❓ PLEASE CAN SOMEONE TELL ME WHAT IS THE NAME OR IDENTIFICATION OF THE WELDING MACINE THAT IS BEING USED IN THIS VIDEO. THANKS.

[@josephleister9198]

Nice job, thanks

[@rktman1965]

I've lengthened bits for years but was never lazy about it like this , use or make a precision jig for crying out loud. The best way is to weld the two pieces right on a lathe that way no wobble and you can turn the over weld off in a few passes.

[@davidschwartz5127]

Being an Electrician for many years I've lengthened drill bits many times, I always used a piece of angle iron for a jig to lay them in after grinding the taper of joining ends and tacked welded then hammered straight as I added more weld. I never had the luxury of lots of time and a lathe on the job site. Also when using these lengthened bits one must continually pull the bit out of the hole to clean out the flutes or you can twist off the weld.

[@JaakkoF]

Even better is to drill a hole to the extension, then turn down the shank of the drill and silver solder them together. Makes for a stronger joint, doesn't bend crooked like in welding and you can always remove the drill and replace it.

[@KableTac]

it doesnt work for needing to drill through stuff like this, but if you just need to extend the drill bit because it's a tight space and the drill simply wont fit there but the drill bit itself is deep enough I like to thread the end of the drill bit then tap a slightly larger bar. thread them together then weld a ring around the top. never had a single one break.

[@nattsurfaren]

Unless you have a machine shop this is pretty hard to do. Or is it? I got an idea. A simple grinding pin and strong glue could do the job. What do you think?

[@paulcookies]

Epic idea, make a video!

[@michaelpeklin7961]

What is "grinding pin"?

[@nattsurfaren]

@@michaelpeklin7961 Asked ChatGPT and it is called a grinding bit.

[@barrykilts4506]

What about dissimilar sizes

[@LarryB-inFL]

Very useful idea...IF you live 100 miles from anywhere. Otherwise, go buy a longer bit.

[@mkarakurt325]

Go buy a longer drill bit

[@tbhorse1970]

Agreed. This guy was a wanker at best

[@tarnowek1]

haters will hate? what if the "longer drill bit " is still too short? at least this man is showing how it can be done...don't like it don't watch simple.

[@JaakkoF]

You really don't just "go buy a longer drill bit" if you need something of 100D or longer. And still, at 20D you start getting into the "no one has it" category without using a gun drill.

[@Jazzforyoursoull]

Precision wobble

[@cszrwi]

Drill bit is high carbon steel. The weld will harden it locally. It will break off real soon. Aneal the area you welded by heating it locally red and letting it cool. Don’t aneal the twist drill keep it cool.

[@biggur5]

With all those tools and such a big workshop I'm surprised you don't already have a long drill bit. The people who need a long drill bit more than likely won't have all those tools!!! If they did have all those tools then no doubt they'll have a long drill bit too! Easier and cheaper to buy one !

[@BoudreauGuitars]

Crude but, effective

[@rameezsheikh7576]

Buy a tungsten carbide insert and weld it to the tip of a Steel bar.

[@CrowClouds]

So easy!

[@adsdentiste]

Τotally amateur! Observe the pitch of the drill! You compared the positions of the holes

[@trevorbyron9448]

And if the drill bit was 4 mm

[@porlibre1211]

Mira, lo primero es asegurar que la amoladora no se mueva tanto y segundo, usa una varilla roscada de diametro inferior, perno acoplador roscado y hazle rosca a la broca del diametro de la varilla y la alargas o acortas sin tantos problemas. La polvora hace años que esta inventada.

[@jackjonson2696]

Nice video thsnks. I need a drill bit extension like that. But dont hv the grinder or erlding equipment an weld skills. Would buy if your selling ?

[@thedailylifediary5804]

Me he atrevido a ver el video hasta el final, haber empezado por el final y no tendrias tantas criticas. Tu sistema tiene un grave problema cuando se trata de piezas macizas, la viruta no sale, prueba el sistema que te he dicho yo y veras que es infalible, siempre que uses un diametro inferior a la broca.

[@huaweilaos1230]

Giovanni

[@Stllno]

Not sure if you needed such a long extension for that job... just sayin’ 😎

[@meadball1]

All the machinists that have watched this are cringing 😫

[@tbhorse1970]

holes are not even straight. Save Yourself the bother and buy longer drill bits ( this just sucks and is click bait )

[@ted7919]

Dump ..... LMAO
