Hallo General, I am in the fortunate position of owning both and of course you are as always right, But the TAMIYA's solid handle with its hex socket allows the use of a proper drill chuck so that it can accommodate much larger drill bits than the regular Pin vise.

Yes indeed....but it doesn't allow those of us with fat fingers to manipulate it all that well ...

Concrete is soft! Slag based concrete & engineering brick isn't.

These are for plastic though, don't plan on building anything with zimmerite (sp?).....

Masonary bits are totally different though right....you wouldn't use those to drill metal or other things really if you are of sound mind that is lol

Yeah the ones you are looking at should be fine..also the two handles...

Like you I would not use anything else but you must be prepared for the extra cost.

I guess for me coolant is one of those things I take for granted and that's why I always forget to mention it. Not needed for plastic or by hand with a pin vise, but definitely for any kind of machining. I use a soluble oil that I can mix with water and I have a pop bottle with a hole in the top for a squeeze bottle and it works pretty good for the Bridgeport. Naturally the lathe has built in coolant. I guess you could say that the first step is to buy good tools, and the second is to take good care of them, eh?

I'd say that wraps it up in a Nutshell
