Carmex CRC0500P18 Indexable Thread Mill 0.5 in Shank

Product Description

The CARMEX CRC0500P18 is an indexable thread mill designed for both internal and external thread milling operations. It accepts a C18 insert style and uses the CRC toolholder style, making it a purpose-built solution for precision thread generation on milling machines. The shank diameter is 0.5 inches, the neck diameter is 0.5 inches, and the overall length is 7.0 inches. Through-coolant capability is built in, delivering coolant directly to the cutting zone to improve chip evacuation and extend insert life during demanding threading passes. This tool is handled by machinists and CNC programmers in production and job-shop environments.

The CRC0500P18 is suited for thread milling applications on both manual and CNC milling platforms. Its ability to cut internal and external threads with a single toolholder reduces setup time and tool inventory. Through-coolant support makes it particularly effective in deep-bore internal thread applications where heat and chip buildup are common concerns. Typical users include metalworking shops producing threaded bores and external threaded features in a range of workpiece materials.

Key Features

• Cuts both internal and external threads with one toolholder
• C18 insert style for indexable cutting edge replacement
• CRC toolholder style for rigid, repeatable setup
• Through-coolant design for improved chip evacuation and heat control
• 0.5 inch shank diameter and 7.0 inch overall length for reach in deep-feature applications

Compatibility

Designed as an OEM-style indexable thread mill accepting C18 series inserts in a CRC-style toolholder. Verify insert compatibility with your specific thread profile and pitch requirements before ordering.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle and coolant system are fully powered down before mounting or changing the toolholder. Confirm through-coolant connections are properly seated and free of debris before running the spindle. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when programming thread milling cycles.
