It took me a few minutes to understand the geometry of your fixture but once I did, this is a superior design. I'm going to make a much larger copy and experiment with it. Thank you for producing this video.

[@KayvanCrafted]

TNX for your comment. I'm so happy that you liked my work.

[@awfab3517]

For wood it works because it's soft and gives so the cutting edge will bite but for metal you need another step so just the cutting edge touches first

[@omarrojas7174]

Exactamente

[@larescats9228]

You are a true craftsman Great video

[@KayvanCrafted]

Thank you. You are very kind.

[@MRantzWI]

Awesome DIY tool ! Just what I needed and saves me a bunch of money ! Thanks !

[@KayvanCrafted]

Thank you Matt.

[@daviddickmeyer5231]

Very nice idea. Everyone should keep one in their toolbox!

[@ypaulbrown]

grat video.....bravo

[@sohishirazi1565]

Your explanation is wonderful and pretty simple. I like it cause it's worthy

[@billysmether6237]

Nice!!!!!!!!!!!!!

[@arielvalenzuela9611]

Perfect thanks

[@DjLheodaTechTv]

Nice sharing

[@andrewdegozaru74]

Ingenious little back-up sharpening tool in case you're not near / don't have a bench grinder + sharpening guide.

[@KayvanCrafted]

Glad you liked it. Angle grinder and drills are essential power tools. Definitely save up some money to buy one, even the cheapest Chinese no brand one are good enough for most people. Don't forget the safety equipment like gloves and glasses.

[@AsianTechnic]

Excellent work keep it up

[@RixtronixLAB]

Creative video, thanks for sharing, like it :)

[@KayvanCrafted]

Thanks for watching, you have a nice channel going on man.

[@gilbertsmith9716]

Good Video...

[@johnburns7512]

Quick & simple - great work👍

[@mehrdadfarrokhnia8361]

Nice

[@jalaloujdik4753]

What liquid did you put in before the piercing?

[@KayvanCrafted]

So my go to is engine oil, you can even use the used engine oil it's ok. A lot of people may not agree with me on this though. I don't like thin liquid like WD40.

[@jalaloujdik4753]

@@KayvanCrafted thank you

[@robertodebeers2551]

Good job.

[@HYTMUAE]

I like it :)

[@datmeme8967]

How about fixing your grinder in a vise and then with the dull bit in a hand drill capable of slow speed (screwdriver mode) approach the grinding surface at the proper angle while the bit is rotating? This will grind down the bit at an identical angle on all sides and conically instead of flat (pyramidal) like the approach in this video.

[@KayvanCrafted]

Thank you for sharing your thoughts with us. I actually tried this exact method, the problem is you are ending up with a bit with a pointy tip, exactly like a cone, and it can not drill through anything. All the shapes and angle you see on the bits they are useful and they are doing things. Bits are simple looking but rather complicated machines. The bit sharpener I have designed here is far from perfect but because it's so simple it is acceptable for most of the home users. for example the tip angle of normal metal bits are 118 degree here I used 120 degree, because of the hexagon nut, the face you are referring shouldn't be flat but it is and it's working. Version 2.0 of the bit sharpener is already done and soon will be uploaded here though with a lot of adjustment capability.

[@datmeme8967]

@@KayvanCrafted Yeah, I was just watching some other sharpening tutorials. Seems like the conical tip will work up to about 3/8" or so. After that you have to create a 7° attack angle for the cutting edge. I'd probably use the cone method for larger bits and then touch up the cutting edges manually.

[@moxee33]

Its terrific! What do you think of grinding the sides next to the bit at 120 degrees ( or whatever it is supposed to be)?

[@KayvanCrafted]

Thank you. I think you I know what do you mean, adding to extra angle by the side of each surface will help the bit to penetrate easier and improves the overall performance of the bit.

[@TheJavaSync]

Nice design, But what's the distance 3mm holes

[@KayvanCrafted]

Thanks man, You can choose 4.5mm between the center of the 3mm and 6mm holes and 6mm between center of 6mm and 10mm holes. I also recommend to use 9.5mm or even 9mm instead of 10mm bits for the last hole if you are using the M10 size nut.

[@dantheman4168]

Although it is an interesting design concept. I would definitely not use a small angle grinder as my first choice unless it was variable-speed. Most of the small angle grinders are in the 11000 RPM range which generates quite a bit of heat on the tip. As a suggestion I would drop the speed dramatically on a variable speed grinder so as to limit the amount of heat generated on The Cutting Edge of the drill bit. You may also opt out to use a quenching method in between or quench it or cool it as it's being sharpened. Just a helpful suggestion. I would also lose that music it is very distracting and is not conducive for instructional purposes. I hope my feedback helps.

[@GurvinderSingh75]

But hot to resharp 22mm or 25 mm drill with it?

[@KayvanCrafted]

Hi Gurvinder Singh, well TBH if I wanted to sharpen that big of a drill bit I'd rather not to use a jig, but I guess if you like to use this technique you just have to find a big enough nut and bolt for your bit. the M10 size here is just an example, the instructions would be the same with smaller and larger diameters.

[@idiotradar1]

Anyone with any mechanical skills would make a bigger one...duh

[@javiermancheno8531]

Excellent approach ! Many thanks for the video youn man !

[@wm.traynor1143]

I became more interested in his jig for stabilising his angle grinder😄

[@safiullaquadrisayedsha5396]

How can disused 118degree

[@KayvanCrafted]

It would be 120 degrees. As you know, the nut is a regular hexagon with 120-degree angles. You can do math with geometry and calculate the angle too.

Спасибо брат

[@garyt7830]

The Problem is your grinding Iratically with the Tool itself, and Just holding it allows it to be out of true.

[@KayvanCrafted]

Thank you for sharing your opinion.

[@dantheman4168]

I would tend to agree that you're not showing consistent results on drill bits especially with smaller sizes. To keep the true you should keep the center axis of the drill bit uniform so that as the Revolutions of the drill start to cut its not off or gives you a wobble.

[@KayvanCrafted]

@@dantheman4168 Thank you for sharing your opinion.

[@ThysLouwrens]

Nooooooooooooo, I want to see you drill metal not wood, I can drill wood with any blunt or broken bit.

[@KayvanCrafted]

I did made a new version with the footage of me drilling through steel, kinda busy but I will upload as soon as I finish editing.

[@BrandonDickenson35]

Had the same thought exactly

[@jeffwestwood]

I couldn’t make one - my drills weren’t sharp enough!

[@KayvanCrafted]

😂

[@LockBits-ts6eo]

Shocker

[@omkarahi]

This attachment will result in a flat surface but the drilling surface is curved.

[@KayvanCrafted]

You are correct, but a sharp tip with flat edges surface is much better than a round tip.

[@mikehall9468]

@@KayvanCrafted Sorry, but unless you angle the trailing edge down away of the bits cutting face, drilling wood is about all this bit is good for..... if that. Nice try.

[@KayvanCrafted]

@@mikehall9468 Thank you for your comment, version 2.0 is on the way.

[@1903bretep]

An interesting idea well presented but spoiled by added music which was distracting and unnecessary.

[@KayvanCrafted]

Guys thank you for the suggestion about the music, noted. BTW, Bitsharpener 2.0 video is on the way, stay tuned. It will take me a while to record it and upload it though, a little busy with other projects.

[@dubblyewjay1133]

I commend you. Did you learn this from a father, machinist mentor? Thank you, and God bless!

[@KayvanCrafted]

Thank you for your kind comment. The idea came to my mind, when I was watching someone making a way more complicated version which was less practical, I just imagined it in my head and build it.

[@user-ls2bn2mw9i]

Why do people insist on having music in a video that distracts from hearing what is being said?

[@KayvanCrafted]

You are completely correct, my early videos; on a side note you can activate the subtitle if it helps.

[@lastride9875]

WOW

[@philcook9967]

Great video, but please lose the music, really distracting!

[@KayvanCrafted]

Thanks for your comment, of course a lot of people have mentioned the music, sorry about that.

[@MRantzWI]

@@KayvanCrafted Just a thought, little off topic: Don't apologize, you didn't do anything wrong. Thanks for the feedback would be good. Remember, you will never please everybody so you'll be doing nothing but apologizing to people ;-) Great video, thanks for the time to post. I'm going to make one of these.

why go to all that stupid trouble of mucking around when you can just use a bench grinder that takes 10 seconds to sharpen a bit , even broken bit you can re sharpen , dont throw them away ,unless they are cheap chinese junk 🤪🤪🤪🤪🤪

Well, some people use a ruler to draw a line, and some don't.... That doesn't mean those who don't are necessarily wrong, though, but I think you got the point.
