spring loaded engraving tool

[muddy0409]

Hi all,
Anyone got any suggestion for where to get a spring loaded engraving bit holder with 1/8 inch shank. I have seen a few 1/4 inch, but nothing smaller.
Thanks.

I have just ordered their 3/4" 'standard' one, awaiting delivery. Price is somewhat hefty, but I'm hoping to get a fair bit of use from it. If you are in the US you will probably have an easier time than I did purchasing it, 2linc dont accept non US CC's or paypal...

What will you be using it for, what type of curve surface. Interested in seeing how it works for you.

A search on ebay for "cnc engraving diamond" will bring up a 1/4" and a 3/8" drag diamond. I have the 3/8"...works very well! I bought a spare diamond. IT has a step down shaft. About 1/2" of the length is .122". That part holds the diamond. It steps up to about .18. The step keeps it in the holder part & allows the spring to do it's job. You could buy one and cut it leaving a .122 shaft holding the diamond, BUT, without the spring loading it seems it would be almost impossible to use. Your parts, clamps, machine, would have to be so very exact so as to not break the diamond.

I've never seen one with a 1/8" shank, as the OP requested. Be a pretty small spring!

Hi: You could make a special holder to mount in place of the router to hold the engraving tool. I've used glued up corian to make many special jigs and part holders and it has the rigidity and strenght to last a long time. It holds a thread for locking screws very well.
