JIS MC-CSLC

Carbide Thread Mills for Metric Internal Threads

Specification

Coating

Product Features

• The same MC-CSLC can process right and left hand internal threads by using the helical interpolating process. The MC-CSLC can process different diameters of internal threads with one tool if they have the same pitch.
• The MC-CSLC can be used for a wide range of work piece materials such as aluminum, aluminum alloy, copper, copper alloy, cast iron, stainless steel, tool steel, alloy steel, carbon steel, thermal refined steel.
• The tool is produced from an ultrafine grain cemented carbide material that offers high wear resistance. It has a special coating to gain additional tool life.
• Blind hole internal thread machining with a few incomplete threads is possible.
• The MC-CSLC is a spiral fluted thread mill that reduces processing torque when compared to straight flute type.

The graph on the upper right is a diagram of the machining torque change of a straight flute thread mill compared to a spiral flute thread mill. The spiral flute thread mill reduces torque by 40% and has a lower fluctuation rate than a straight flute thread mill. ＊For the details of how to use thread mills, please refer to Technical information P.72 to P.78.
