Advantages of Hitachi JDMT150508R PTH30E Milling Insert
- PTH30E multi-layer TH coating: Ultra-low friction coefficient effectively suppresses chip adhesion and built-up edge, greatly improves wear resistance when processing sticky stainless steel & titanium alloy
- FW optimized chipbreaker: Balanced chip curling performance for both rough and semi-finish milling, prevents long strip chips tangling around cutters
- Double-sided 2 usable corners: Double service life compared to single-edge inserts, reduces overall tool cost
- 15° positive rake design: Low cutting resistance, lowers machine spindle load and reduces machining vibration
- Original Japanese ultra-fine grain carbide substrate: Excellent toughness to resist edge chipping under interrupted cutting
- Universal matching compatibility: Fully interchangeable with all standard Hitachi AHJ/AJX series shoulder milling cutters
