Search for extra long bits

[Molo1818]

Hi guys,
I’m specifically looking for a 1/4” shaft, 4 or 5 “ long, tapered ball bit with a tip around 1/16th” diameter. I’m doing 3d carving and my 3” bit just isn’t long enough…….. oh what I would do to have a few more inches!!!!! Lol ????
Thanks for any leads

Either should be able to supply what you want.

I have serious doubts that a long bit with a tip diameter of 1/16" will survive more than a second or so unless you are cutting foam.I have used a pin chuck in a 1/2 inch collet in the past and a 1/8 tip diameter was feasible,but your situation might not allow access even for the pin chuck.

Indeed. We tried out a 1/8 diameter cutter that was 1" long on MDF recently. Unless we take it in 2mm passes at about 3m per minute, it snaps.
