@@CheZfrmdaWestWiscexactly 🤣 I’m starting out in machining, and while I understand the “x” shape the tip of the bit needs to make, I definitely have not developed the skill very well at all
I learned to sharpen drills in the Air Force (RNZAF) in 1985. Just today, I had to sharpen a bit for a maintenance project I was working on. I told my son that I could probably remember how, but it may take me a few tries. This tutorial is bang on.
There's always "those people" who have to leave a comment on why they think you're doing whatever wrong, how long they've been a machinist, blah blah blah.. Personally, I see a mighty fine, well sharpened drill bit! Great job!
I actually worked this out myself using an angle grinder. This really does work great on pretty much any type of drill bit, even if you don't do it perfect, it's still better than a blunt bit,.
It will cut. If you want a hole the stated diameter of the bit then you need to get the sides even so the cutting forces are the same on each side and it doesn't wobble. A lot of the time you don't care that the hole is that accurate though so being a little off doesn't matter so long as it cuts well. A lot of people should be able to do better than the grind on those cheap Harbor Freight bits.
An angle grinder? Really. If it'd not in a vice then I fi d that hard to believe because the angles have to be very precise. Tried it many times on the bench grinder and it's not easy
@@tylerboss It's not that hard to do on an angle grider, on smaller drills it is even easier when you can sharpen them from behind. It won't make them perfect but if 5mm drill goes through 3mm stainless flat steel with ease free handing it's enough for me.
Nice split point. They are unnecessary if you have a pilot hole but are great to have. If your chips are uneven, then you'll need to take more off one side or the other. Great teaching👍
This is how my Dad taught me, as well as 4 years in machine shop in high school. Never had a twist drill work longer or harder than this sharpening technique.
I sublease to one of the best tool grinders in my area and I always pick his brain when I hand sharpen tools on a grinder and everything you did is spot on to what he says.
Checks out. Our shop works with fiberglass and we relieve all of our drills like this on the backside of the flute. We have a drill sharpener to set exact angles on our drills and reliefs but same bit pattern. 👌🏻 I know personally I have not hand set a relief like you tho! Great video!
That’s how I learned. I also had access to a precision split point drill sharpener which helped me understand the science of it all. That’s a great looking split point!
That's how i sharpened them 40 years ago. Pro tip: if you have a hole spec'd a few thou bigger than your drill bit, just sharpen it a teeny bit more on one side than the other. Acme-Gridley multi-spindle screw machines were excellent test beds! Brutal.
*GREAT VIDEO MAN, I SHARPEN ALL OF MY DRILL BITS THE SAME WAY ON A BENCH GRINDER. EVERYTIME I TRY TO TEACH SOMEONE NEW, HOW TO SHARPEN A DRILL BIT, IT CAN BE DIFFICULT EVEN IF THEY ARE WATCHING OVER MY SHOULDER. I THINK MY TEACHING DAYS ARE OVER, IM GOING TO SHOW THIS VIDEO TO ANYONE THATS WANTS TO KNOW HOW TO SHARPEN A DRILL BIT FROM NOW ON. YOU DID A FANTASTIC JOB FILMING AND EXPLAINING YOUR EXPERT SKILL HERE 👏 👍 GREAT JOB!!!*
Almost exactly how I was taught except I learned to rotate the drill slightly while rocking it back and forth. The game changer is the release angle that’s ground on the cross cutting edge, makes it cut like a dream 😍
Grinding bits on a disk sander is beautiful, so much better than bench grinders because you can actually see (or is easier to) the angle you’re grinding. On bench grinders I use the sides of the wheel (it’s all fresh and flat) to make my final angles
Beautiful job I know more men that ruin drill bits on a grinder than can get them to cut even wood again let alone properly and beautifully thin a web love to see people holding onto a lifelong skill
Nice! Getting the initial angle decent is challenging without any kind of jig from my experience. I like how you explained the different sectors/angles as it tough to visualize. Try an 0.03125" drill😉 i do those with a dremel and reading glasses. Cheers
Learned to do this as apprentice 3 decades ago! Journeyman gave me old drills to practice on and compare to new ones. It's a good skill to learn 👌 like riding a bike as they say 😊
Oh my gosh! This is similar to the way my tradesman(who was seriously good) taught me. Grind the cutting faces flat, go for an angle between 125-135 included, put some back clearance on for chip ejection and if sharpening larger bits thin the point slightly with the corner radius of the wheel. First time I've seen this online
Good video! In the shop, we use a darex drill sharpener (basically a commercial drill doctor). It's fast, makes a razor edge, and a perfect geometry every time 👌
99% of people will get a much sharper drill using a drill sharpener than trying to do it by hand on a grinder. I believe I have a drill doctor somewhere in my cellar, but I don't think I have ever used it yet.
Nice one , as a ex toolmaker the proof of a well hand ground drill is in the use of such a tool and so if it cuts equally and to size it is gold star time👍🏼
A little less pointy chisel edge would be great for tool life. Otherwise I do it exactly the same. Sharpening drills is an art especially if you work with stainless or brass there are some nice hacks to not make em bite as much but get nice chips of it✌🏻
Perfect. I've used a scale/square to eye that angle and length of edge for balance. And thinning the web I've used on parabolic Ex long on coolant Jacket. Good stuff !
Sharpen all my drills by hand - people always tell me that drill jigs are available - I can sharpen several when it takes so long to sharpen one with a jig - Split pointing a drill is excellent - symmetry is key - I place my left thumb in the flute of the drill them spin it 180o to get main angle and rake angle 👍👍👍👌👌👌👌
When I did my machinest trade one of the first tooling jobs we did was hours of learning how to sharpen drills for different applications 👍 this is good
This video IS spot on but don't forget the water !! You have to keep the material cool ! Always grind without gloves because if the material is hot to the touch, it's time to dip into the water
Get yourself a drill doctor and it does a nice job. I still sharpen some by hand when they won’t fit in the drill doctor but the drill doctor is the ticket.
Very good sharpening. Room for improvement tho. I notice that the outer edge is the first to go. So I chamfer outer ring a bit, so it shares the load a bit more when cutting.
Wow cool!! My ex-husband was a machinist you see all those little shavings. He used to bring those little shavings home in his clothes and they would get in my washing machine. I hated that ⚜️🐊🇺🇸🏡👋😎
Perfect. Then for brass and plastic, grind a flat on the flutes at the cutting edge to prevent the drill being sucked into the workpiece. Knowing how to effectively sharpen cutting tools by hand makes life in the shop a whole lot easier.
@@wholesomesunbro1 grind a small flat on the leading edge (cutting edge) of the flutes, nearly perpendicular to the workpiece to create a blunter edge.
@@wholesomesunbro1 no problem. The grind should be slightly larger than your feed/rev so the angled flute doesn't get a bite and therefore doesn't suck into the workpiece.
There are many ways to sharpen a drill bit offhand on a pedestal grinder. I like to start at the tool rest & ride the grinding wheel up then make it a split point like he showed
Very nice grinding, though i would still say you should slightly rotate the drill as you upsweep to give it rotational rake as well as flat rake. Matters less if you thin the point as well as you did, but I twist and uplift at the same time, to make it look like a new drill, then thin the point if the drill's going to be coring out. Drill point grinding is an art in itself. Guhring do flat grinding and a thinned point on their drills and they're some of the best i've used, but for hand grinding and considering the state of most workshop grinding wheels, i'd avoid point thinning and go for a twist and uplift on the wheel.
Very nice just learned how to do this for my apprentiship. Do you use any key or measuring device to look at the 118 angle or that the two sides are symmetric? I've been able to get amazing surfaces but sometimes drill 0.2mm to big due to inbalances
For the angle, you can use two hex nuts put together that will give you a 120° Angle. Bits vary in their angle from 118° to 135° depending on its intended use. Doesn’t have to be perfect to get a desired result.
If your holes are drilling oversize that would mean the tip of your drill is off center due to inconsistent grinding, you need a drill angle gauge to check centerline. .2mm is a looooot.
You don’t necessarily have to do that 2nd step of grinding a split-point, but you made it look effortless lol. I usually go crazy/lazy making split points, and give it a wickedly excessive relief angle… which probably isn’t consistent side to side lol. I only care about the main grind.
It almost looks like he did that BY HAND - by hand - BY HAND AND BY EYE - HE DID THAT BY HAND -±±that's what it looks like anyway... BY HAND - I say by hand BY HAND AND BY EYE 😮
Making a split point known as sharpening the secondary cutting edge is not necessary because you do not suppose to use a 9/16" drill bit without a pilot hole first. Everything over 1/4' requires a pilot hole with a 60% of the next diameter. Of course we don't do it because is time consuming and drill bits are cheap, but so it should be. The center of the drill bit doesn't cut because does not have the necessary speed. The center of the drill bit is squeezing and pushing the metal away under pure pressure we apply to the drill.
A Drill Doctor can makes this Procedure a whole [Hole? 😊] a Whole Lots EASIER, & MORE UNIFORM! Especially as to making a Split Point Sharpening! ThanXx for the Content and the Sharing!
I do this all the time with an angle grinder. Same concept but definitely not a result that good. When you have destroyed your but hitting concrete though a grinder sharpen is still 100% better than a blunt bit
It's good but not provide control when dealing with bigger diameter drills,so insted of grinding relief to edge grind it edge to relief. By this way (opposite grinding) you have control drill's relief angle and it ables you to see that where you are grinding and how much you grinding
Man it's been FOREVER since I've hand sharpened a drill. Seeing as I've been doing primarily Swiss work now I don't see anyone hand sharpening a tiny ass .014 drill.
Im clumsy and erratic, so I get my angle and hold my left hand against the plate, then it stays there until done. Muscle memory will get it back at the right angle after twisting or cooling.

Great grinding skills.
I went to machinist school in 1992. And this is exactly how they taught us
You roll the same chip out of both sides and you got her nailed!
Correct that's the best drilling procedure
Making a split point known as sharpening the secondary cutting edge is not necessary because you do not suppose to use a 9/16" drill bit without a pilot hole first. Everything over 1/4' requires a pilot hole with a 60% of the next diameter. Of course we don't do it because is time consuming and drill bits are cheap, but so it should be. The center of the drill bit doesn't cut because does not have the necessary speed. The center of the drill bit is squeezing and pushing the metal away under pure pressure we apply to the drill.
