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,

[@almacdonald2506]

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!

[@JonasWanted]

Good to know! Thank you for the excellent class!

[@alanharwood6846]

Good demo
i taught this for 34 years of teaching machining

[@ypaulbrown]

fantastic video, well photographed. great information, thank you

[@nigelritson9910]

Excellent information and presentation-thank you.

[@TonyDalSanto]

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

[@alanharwood6846]

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

Did thousands of them, a cutter grinder makes it easy

[@montanaplease]

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

[@MegaRiffraff]

👍🏻

[@HansFormerlyTraffer]

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

[@luizguilhermecosta7221]

[@alanharwood6846]
