How to Hand Sharpen a Drill Bit

[raysimon]

That is exactly the right way to hand sharpen a drill very few people know how to do it and even less that can do it this is the only video I have ever seen on utube from a retired machinist

This was exactly how our head machinist sharpened his bits.
He was a machinist for over 40 years. Retired a couple years back. I miss Mr. Colin.

That’s perfect! The drill swarf spirals speak to that fact!

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.

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, .

I've been a machinist for 19 years and that looks like a great drill tip to me!

If it produces the results you need, you did it right.

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!

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👍

[jimmurphy]

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.

That is the correct way to sharpen a drill. Only a hand full of people can actually do this. Back in 1990 when I was doing my apprenticeship, I had to sharpen hundreds of drills and that made me master it. Great video.

Running a gang drill press with multiple lathe chucks to hold drivetrain E-brake forgings. Large 1.5" bits that broke on junk in the metal. Would walk to the other side of the shop when I had three or more to the only bench grinder in the plant. I just used my 6" scale to check center.

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!

In the late 60's I started my 5 year apprenticeship and I started with a bucket of drills to sharpen by hand, I spent a month honing that skill, I am also pleased to see someone is carrying on with that skill, which unfortunately is dying out.
I take my hat off to you

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.

[AndrewCampbell-utjk]

I've been hand sharpening drills for over 50 years, great to see other people with these basic skills.

[repsacca]

I done this thousands of times and i can say you done a very good job there ❤

[kevinsnell]

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!

[jimbasile]

I sharpened drills this way for years. I preferred hand grinding over the Black Diamond machine. Nice work!

[frankewhite]

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 😍
