Pin drills

[jarndice]

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 ...

Use to break 3mm masonry bits all the time at my old house. They built a load of Sheffield terraces with blue (engineering) brick.

...So what are we talking here....You going to drill holes in your model or cement ...Cause that set you're asking about will never go through cement ..they are made for plastic...and will probably serve you well so long you don't put pressure on them like you are drilling cement

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...

GARY Hi, One thing I would say about using COBOLT TIPPED Drill Bits is you really must not let the tip overheat so a constant use of a thin oil is vital on the bit while drilling,
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
