Sumitomo Electric has listed ultra-hard drills and supports high-efficiency machining through additional oil holes.
Figure: "Super Multi Drill HGS type" with additional oil holes and support for MQL processing. Sumitomo Electric Industries has launched the "Super Multi Drill HGS" (pictured) with a general-purpose super-hard bit with oil holes. The drill has added oil holes to the "Super Multi Drill GS" listed in Sumitomo Electric Hard Metal (Headquarters: Itami City) in 2008 to support internal oil supply and MQL (Minimal Quantity Lubrication) processing (see this site report). . Holes with L/D (machining depth/machining diameter) of 3, 5, and 8 can be machined. PE Pipe Fitting electrofusion is used for gas and water, design and fabricated according to standard GB and ISO. The electric welding is much stronger than butt welding and sock fusion with less leaking risk. The copper wire and Nickel alloy wire is saftly for gas. the PE electrofusion pipe and fitting is convenient for installation and maintance.
