(for low cutting force) improved tool life by 1.6 times ② Insert for welded & hardened steel (-W type) 1. Improved insert strength and achieved longer tool life. 2. Suitable for welded & hardened steel (over 50HRC) ③ Insert for semi-finishing (main blade -H type) 1. Main blades -H type for semi-finishing are available for φ20mm,φ25mm andφ30mm. In case of using -H type blade, please confirm the grade of both the inserts. It should be the same grade. 2. Able to use for semi-finishing by improving nose radius accuracy. Do not recommend to use for roughing. ● INSERT COMPARISON SWB-HM type SWB-HM-H type Regular type For Semi-finishing R min. 14.906 R min. 14.938 R max. 14.981 R max. 14.983 – 0.05mm 180° – 0.05mm 180° R14.95 + 0.05mm R14.95 + 0.05mm Radius form accuracy on body Large gap off the center Small gap off the center Regular type For Semi-finishing SWB-HM type SWB-HM-H type C157
