Hello don.
I bought it on Amazon at Argofile SBH-35...
It's quiet, precise, powerful, and has an adjustable rotation speed.
The chuck is also solid with one touch. A switch pedal is also included.
I've been using it for more than 3 years, but it's durable and a little expensive, but I recommend it.
The bit (tip tool) was purchased separately.
Normally, it is used with clockwise rotation, so if there is a corner at the beginning of shaving, it will be repelled and dangerous.
When removing laser soot or cutting bevels,
Scrape lightly from a place where there is no step.
When scraping small steps, use a thin bit so that the excess will not dry out.
Soot removal is easy and quick.
Please wear a mask.
Of course, the accuracy of drilling holes by attaching a drill is also the best.
