Topic tags/keywords: carving tool sander

Hi all,

My son told me about a power sanding/carving/grinding tool called a Dynafile (by Dynabrade), thinking that it might be useful for some of my work reaching inside tight places.

Since they seem to start at a few hundred and go up, it seemed like a good idea to ask here first.

Any opinions or experiences welcome.

The dynafile is nothing new and there are many low cost options. Google bandfile…
I recall using bandfiles as long as 30 years ago.

Hi Bob, I have had a Dynafile kit for over 20yrs for metal working. The kit has three belt heads, the narrow one is 1/4” I think.
The air motor has torque at very low speeds unlike the imports, that is why they are expensive. The way I use mine is, I have a filter/lube/regulator right at the work. Holding the tool with a thin dear skin glove, and compressing the tools lever all the way in, I regulate the speed with the air regulator, helps greatly with fatigue.
That is where the torque is important to match the material and the belt grit, getting the right speed and holding it.

Have your say...
