MITSUBISHI MATERIALS CORPORATION Metalworking solutions company (Company President: Tetsuya Tanaka, Address: Marunouchi, Chiyoda-ku, Tokyo) has added VQ4WB to the series of SMART MIRACLE end mills with a multi-functional lollipop end mill for difficult-to-cut materials.

The SMART MIRACLE end mill series are highly valued by many customers for the improvement of machining efficiency and the longer tool life when machining titanium and heat-resistant alloys. This is achieved by adopting an (Al,Cr)N based coating, which greatly improves wear and cutting resistance as well as providing better chip evacuation.

Due to the popularity of 5 axis and multi-functional machines, there has been a growing demand for highly efficient machining and process integration with specialized and multi-functional tools. To meet the demand, Mitsubishi Materials has added VQ4WB a multi-functional lollipop end mill for difficult-to-cut materials to expand the series.

Main feature of VQ4WB:

1. True round ball cutting edge over the full 280º achieves stable cutting even during undercut machining.

2. The original (Al,Cr)N based coating improves adhesion and wear resistance and provides a longer tool life over a wide range of work materials, from carbon steels through to difficult-to-cut materials.

3. A range of dedicated diameter sizes for deburring of back hole faces are available
- (DC = 1.3, 1.8, 2.8, 3.8 and 4.8 mm)

4. 4 flutes greatly improve feed rates and efficiency compared to conventional 2 flute lollipop end mills.
