In American Standard Association (ASA) system, if the tool nomenclature is 8-6-5-5-10-15-2 mm, then the side rake will be

Explanation:

American Standards System (ASA): 

Back rake angle (αb) - side rake angle (αs) - end relief angle (γe) - side relief angle (γs) - end cutting edge angle (Ce) - side cutting edge angle (Cs) - Nose radius (r in inches).

n ASA system, if the tool nomenclature is 8 - 6 - 5 - 5 - 10 - 15 - 2, Hence the side rake angle is 6° 

Additional Information

Orthogonal Rake System (ORS): 

i (inclination angle) - αn (Normal rake angle) - Side relief angle - end relief angle, end cutting edge angle - approach angle - nose radius (r in mm).
