"Drilling" of square holes

[73Shakes]

Actually ur drilling a round hole then making it square with a file

[1960markN]

That's how I have been "Drilling Square holes" for years.....

[onlywhenprovoked]

"graduated drill"? ? ?

The drill isn't "graduated", the bit is.

and it's called a "step bit" here the US.

where it was invented.

@onlywhenprovoked drill bit i guess it was understood

[Geraldtoo]

Maybe after many years this guy learned this technic from his square peg/ round hole exercise's

[boatkrazy]

Amazing! How did he figure that out? If the Chinese find out about this technology, we might lose more jobs here in the U.S.

maybe should be titled how squares drill round holes and then make them square..just a thought

[LoopyHex]

Hmm. drilling a hole. drilling a hole. filing the hole.. filing the hole..

does that not sound wrong to you? i mean look at 0:23... Yes, file that hole up and down...

This is drilling a round hole, not drilling a square hole. It should be called "How to make a square hole by drilling and filing"!

[fingerfisty]

[adisharr]

[adisharr]
