Carmex SR0375H12 Indexable Thread Mill 0.37 in Cut Dia

Product Description

The CARMEX SR0375H12 is an indexable thread mill designed for precision internal thread milling operations in metal components. It features a 0.37 inch cutting diameter and accepts one IE-style insert secured by a screw-clamp holding method. The toolholder is machined from alloy steel for rigidity under milling loads. A through-coolant channel runs the length of the body, delivering coolant directly to the cutting zone to improve chip evacuation and extend insert life. With an overall length of 3.35 inches and a 0.75 inch shank diameter, this tool is sized for standard milling machine and machining center spindles used in production and maintenance environments.

The SR0375H12 is suited for thread milling applications in machining centers where precise internal thread profiles are required. The 0.51 inch maximum hole depth supports shallow to mid-depth threading passes in materials typical of alloy steel workholding and component work. The 0.30 inch neck diameter provides clearance in bored holes. This tool is commonly used by machinists and tool-and-die professionals in job shops, production facilities, and maintenance machining operations requiring repeatable thread quality.

Key Features

• Through-coolant design for improved chip evacuation and insert life at the cutting zone
• Screw-clamp insert holding method for secure, repeatable insert indexing
• Accepts one IE-style insert in size 12 mm for thread profile flexibility
• Alloy steel toolholder construction for rigidity during milling passes
• 0.30 inch neck diameter provides bore clearance in tight threading applications

Compatibility

Designed for use with IE-style inserts in 12 mm insert size. Compatible insert screw is S12 and the drive key is K12. No additional specific model or system compatibility data was provided in the product data.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop lockout-tagout procedures. Confirm shank-to-spindle interface is clean and free of burrs before clamping. Torque the insert screw to the insert manufacturer specification using the correct key to avoid over-torque damage to the screw or insert seat. Verify through-coolant passages are clear and that the machine coolant system is compatible with the tool body before operation.
