Competitor A Competitor B
MSRS90 doubled the cutting efficiency compared to competitor A. Competitor A required 2 passes MSRS90 improved the cutting efficiency to 1.3 times that of competitor B. Competitor C machined with
(D.O.C.ae=0.1182.56"). MSRS90 completed the cut in only 1 pass. Cutting time was reduced. D.O.C.ae=0.20x1.97". Tool cost is reduced to 1/3 although competitor C is expensive using 2-corner
inserts. MSRS90 reduced machining cost as well as improved cutting efficiency. (User Evaluation)

Competitor C Competitor D
MSRS90 doubled the cutting efficiency compared to competitor C (D.O.C.ae=0.1970.394~1.968"). MSRS90 improved tool life to 1.5 times that of competitor D. Competitor D required 2 passes INDEX
MSRS90 doubled the axial D.O.C. due to lower cutting forces. MSRS90 can increase D.O.C. as the cutting
speed (Vc=325 increases to 490). This resulted in total cutting efficiency improvement. (User Evaluation) (D.O.C.ae=0.4720~0.394") with a low feed rate (Vf=15.748ipm). Competitor D was very noisy due
to large cutting forces. MSRS90 reduces the cutting force and noise level. (User Evaluation)
