Applications/Examples of results
◎Compatible with general-purpose machines In addition to machining centers, high-precision deep hole processing can be performed more efficiently than long drills on general-purpose machines such as N/C lathes and turret lathes. ◎No guide bush required Since processing is done using a pilot hole (guide hole), a guide bush is not necessary. ◎Processing possible with low cutting oil pressure If using a horizontal general-purpose machine, processing can be done even with low cutting oil pressure (1 MPa) (for diameters of 6.0 mm or more). *For more details, please request materials or visit here. http://tool.muraki-ltd.co.jp/muraki-drv-gd.html
