Carbide Oil Hole Non Step Borer for Cast Iron High performance even for MQL (mist) machining High-efficient machining of cast iron with long tool life Hitachi Tool Engineering, Ltd.

Remarkably high performance for boring in cast iron. Machining with high efficiency and long tool life reduces machining costs. Ideal for environmentally friendly MQL (mist) machining! Employs new flute shape. Effect of indented flute shape and special perimeter corner shape suppresses wear. Also effective for anti-chipping for through holes. Special groove shape smoothly ejects chips. Double margin provides firm guide. Stabilizes tool movement during machining to provide stable machining. Uses TH coating which is durable against wear and oxidation. Fragile oxide develops peeling and wear. Fine,...

Cutting Conditions Setting of Cutting Conditions ®These internal coolant cutting conditions are for when using a water-soluble cutting lubricant. Further, for diameters of ^5.0 or less, a coolant pressure of at least 2.0MPa is required. ©As general criteria, feed rate should be set to 7.0% of tool diameter or less when machining holes of 10X to 20X tool diameter and to 6.0% of tool diameter or less when machining holes of 20X to 30X tool diameter. ©When performing MQL (mist) machining, depending on the mist equipment or discharge amount from tool, it may be necessary to reduce feed rate to perform...
