The "Whiz" Atwood Bit
Incredibly designed bit removes calluses with ease. Holes in the side of the bit allow for air to circulate reducing heat when used on the skin.
Atwood bits are of the highest quality for your electric file. Don't risk damaging your hand piece with bits that are not concentric and cause excessive vibration.
I bought this to use on diabetic clients instead of a sanding cap. It's not as effective as a sanding cap as it's very gentle, but that's what I prefer for diabetic and other immunocompromised clients..
It never got hot and smoothed beautifully!
