Couldn't resist :)

P.S. No size ref' it could be a little tiny model of one!

John Stevenson:
Not sure what size it is, it started life as a 5 Morse taper which has enough meant on the shank to convert it to R8

You can often get these at car boots for peanuts as they don't think there is any life left in them but in fact you want just the worn out stub.

Ralph,

I don't look at the drill size when working in the rough, I just use one that is big enough to get rid of excess material.

The one I used was from a slightly larger 'blacksmiths' set, having a 3/4" shank rather than the standard 1/2". I have had these for a fair while now, but only just starting to use them in anger. I could use them on the mill in a collet, but I had no chuck large enough to hold them in my lathe tailstock. But RDG came to the rescue fairly recently when they started to sell these, which match my other hand tight chucks, and the quality is great for so little money. 6th one down, 5 to 20mm keyless.

I also treated myself to an R8 one for the mill at the same time and price.

I thought you would have noticed them on my drill rack when we were in there the other weekend.

Using large drills can save you hours of machining time, by getting rid of excess material very fast before final boring.

The only big drill I have is a 3MT 1" and I love it! My grandad must have sharpened it as with about 1/4" pilot hole it'll go through anything - if the time ever comes when I need to sharpent it I'll probably cock it up though!
