Carmex SRC0750J18 Indexable Thread Mill 0.54 in

Product Description

The CARMEX SRC0750J18 is an indexable thread mill designed for cutting internal and external threads in a milling application. It accepts C18 and S20 insert styles and uses a screw-based insert holding method for secure, repeatable positioning. With a 0.54-inch cutting diameter and a 0.75-inch shank diameter, this tool is built for thread milling operations where precision and tool rigidity matter. Through-coolant capability is integrated into the body, supporting chip evacuation and heat management during aggressive cuts. A maximum hole depth of 1.89 inches accommodates a wide range of threaded feature depths. Machinists and tool and die professionals working with CNC machining centers are the primary users of this toolholder.

The SRC0750J18 is suited for both internal thread milling in bored holes and external thread milling on cylindrical features. Its CMT toolholder style is compatible with standard CNC spindle setups. The through-coolant feature makes it effective in materials that generate significant heat or require continuous chip flushing. This tool is appropriate for production environments and job shops running thread milling cycles on vertical or horizontal machining centers where consistent thread quality is required.

Key Features

• Accepts C18 and S20 insert styles for flexible thread profile options
• Through-coolant design supports chip evacuation and thermal control
• Screw-based insert holding method for secure, repeatable insert seating
• Handles both internal and external thread milling in a single tool
• 0.75-inch shank diameter provides rigidity in standard CNC toolholders
• CMT toolholder style for compatibility with common machining center setups

Compatibility

Compatible with C18 and S20 insert styles. Designed for use in CNC milling applications requiring internal and external thread milling capability with a CMT-style toolholder.

Installation Notes

Installation and setup should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or changing inserts or mounting the tool in the holder. Verify that the shank is fully seated and clamped to the correct torque per the machine tool manufacturer specification before running. Confirm through-coolant lines are clear and coolant pressure is set appropriately for the material being machined before initiating a thread milling cycle.
