The 5-1 safety Fine bit is the perfect bit for any beginner or advanced nail tech.  With a safety edge, it will allow working in an area close to the cuticle, with a lowered risk of cutting the client.  The fine grit allows working with with or gel-x without the risk of over-filing.  Like its brother, the extra fine bit gives more grit to those who need it.  The perfect companion for smoothing and finishing sets.
