Grinding a Flat Bottom Drill 

In school I was taught to stand off to the side of a grinding wheel while it came up to speed, as that was a more likely time for a wheel to come apart. Don’t know if that is true or not. Good video, thanks!

Flat bottom drills, you make the machinist world go 'round.

let's see it cut then

thank's for that buddie. i needed to add square bottom hole to a cyl head this has got me out of trouble your a champ,

I wonder why you can’t just buy drillbits already done ?

fantastic video, well photographed. great information, thank you

Would love to see a technique to sharpen end mills next!

Excellent information and presentation-thank you.

Good demo i taught this for 34 years of teaching machining

Thank you for a great video

So that's how they teach it in a school. Interesting. My way is a little different.

this is great. the end mill is fine if you interpolate the bottom if you plunge with the end mill it will leave a slight angle on the bottom as the endmill has a slight angle to the center of the mill. I also used to teach how to sharpen a sheet metal bit,, as for grinding wheels I like a Norton Wheel 32A 46 or 60 K5 VBE, wonderful for sharpening drills and HSS bits,, dont grind mild steel on it

Good to know! Thank you for the excellent class!

Did thousands of them, a cutter grinder makes it easy

Thank you.
