Carmex MIR4L15A60 Single Point Threading Tool Internal

Product Description

The CARMEX MIR4L15A60 is a solid carbide single point threading tool designed for internal thread cutting on CNC lathes and turning centers. It handles a minimum threading diameter of 0.16 inches with a cutting depth of 0.59 inches, covering a thread pitch range of 24 to 32 TPI (0.80 mm to 1.00 mm pitch). The 60-degree profile angle suits standard unified and metric thread forms. A TiN (titanium nitride) coating improves surface hardness and extends tool life in production threading applications. At 2 inches overall length, this tool fits standard toolholding systems used in precision machining environments.

This threading tool is intended for internal threading operations in small-bore applications where minimum bore diameter is 0.16 inches. Right-hand thread direction makes it suitable for the most common threading scenarios encountered in job shop and production machining. The coolant-through design supports chip evacuation and thermal management during high-cycle threading passes. Machinists and CNC operators working in aerospace, medical, automotive, and general manufacturing will find this tool appropriate for tight-tolerance internal thread work.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision threading
• TiN coating extends tool life and reduces friction during thread cutting
• Coolant-through capability aids chip flushing and heat control
• 60-degree profile angle compatible with standard unified and metric thread forms
• Right-hand thread direction for conventional threading operations
• 0.024 inches projection from edge for precise depth control

Compatibility

Designed for use as an internal single point threading tool with a 4.00 mm shank diameter, compatible with toolholding systems accepting that shank size on CNC lathes and turning centers.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and the control is in a safe state before indexing or replacing cutting tools. Verify shank clamping torque per the toolholder manufacturer specifications and confirm tool projection and runout with an indicator before beginning a threading cycle. Always program a proper thread cycle with appropriate infeed and spring passes to protect the tool and workpiece.
