2 Corner Radius End Mill for High Efficiency Titanium Alloy Machining The combination of 5 flutes and a coolant hole enables rough cutting of titanium alloys with high efficiency. Corner Radius (Emphasis on Sharpness) The seamlessness between the corner radius and peripheral cutting edges suppresses abnormal wear and provides stable tool life. (Non-standard corner sizes are available by special orders.) 5 Flutes Optimization of the she improves chip evacuation, and is ideal for slot milling with deep depths of cut. Center Through Coolant Hole Ample cutting fl uid is supplied to cool the cutting edges and make chip discharge smoother. 1

Irregular helix fl utes allow surfaces to be fi nished with excellent quality.

3 Irregular Helix Chatter and vibration are controled even when processing shoulder milling with deep depths of cut. Application Example MRR ( Removal Volume per Minute ) : 250cc/min Can be achieved Deep depths of cut can shorten machining time. Irregular helix fl utes allow surfaces to be fi nished with excellent quality.

(Note 1) SMART MIRACLE coating has very low electrical conductivity; therefore, an external contact type of tool setter (electric transmitted) may not work. When measuring the tool length, please use an internal contact type (non-electricity type) or a laser tool setter. (Note 2) When cutting titanium alloys, the use of water-soluble cutting fl uid is effective. (Note 3) The irregular helix fl ute end mill has a larger effect on controlling vibration when compared to standard end mills. However, if the rigidity of the machine or the work material installation is poor, vibration or abnormal sound can occur. In this case, please reduce the revolution and the feed rate proportionately, or set a lower depth of cut. (Note 4) If the depth of cut is smaller, the revolution and the feed rate can be increased. (Note 5) For slot milling, use a chuck with high clamping force. 4
