How can you tell the difference b/w a high and low speed hand piece visually?

Question

Any tips would be nice. Thanks!

Answer 1

Not sure why you would need to know this.

But a high speed hand piece is usually smaller and thinner.  If you look at where the bur goes, it will be a small round hole.

A slow speed therefore is usually larger and thicker.  The hole where the bur goes is bigger.

Also, a high speed usually shoots water, whereas most slow speeds do not.
