Re: [CAD_CAM_EDM_DRO] Re: die grinder - HF trim router

I have a Dumore which has been a good grinder, but
they don't provide a square surfacr to mount. I understand
that if they want you to mount to a tool post, they provide
a square surface, If it is just to be used by hand, no
mounting surfaces are provided. The trimming router
has provisions for mounting. I considered using the
HF Hi speed spiral cutout, but there is no provision for
mounting. It is about the same price as the trimmer so
I will keep the spiral for what it was intended, cutting
outlet holes in drywall. HF doesn't come close to
some of the more professional tools in quality, but
I am not using them for production. I can slow down
a little bit and if I do break something, it doesn't set
me back that much.

I purchased a HF die grinder and the body is plastic and hard to hold
firmly.

the collet was so poor that I had to re-make one for myself and also
grind the spindle to remove the rough surface in it.

I can't see such a unit being better than the Max NC spindle.
