Scientific Cutting Tools TMLR5-.8MMELA Thread Mill M5

Product Description

The SCIENTIFIC CUTTING TOOLS TMLR5-.8MMELA is a long-reach, helical flute thread mill designed for cutting internal metric threads in a CNC machining environment. Built from submicron-grade solid carbide and finished with an AlTiN+ coating, it delivers the hardness and heat resistance required for threading operations in ferrous and non-ferrous materials. The tool features 3 right-hand flutes, a 0.15-inch cutting diameter, and a 0.6-inch length of cut, making it suited for producing M5 x 0.80 Metric Coarse internal threads in confined or deep-bore applications. A 1/4-inch shank diameter provides rigid tool holding in standard ER or shrink-fit collet chucks.

This thread mill is intended for use in CNC machining centers performing internal thread milling on workpieces requiring M5 x 0.80 Metric Coarse threads. The long-reach design allows access to threaded features that are recessed or require clearance past surrounding geometry. It is appropriate for production and job-shop environments where thread milling is preferred over tapping for improved thread quality, tool life management, or the ability to adjust thread fit with a single tool. Machinists and CNC programmers in aerospace, automotive, medical device, and general manufacturing are the primary users.

Key Features

• Submicron-grade solid carbide construction for wear resistance and edge stability
• AlTiN+ coating provides heat and oxidation resistance for extended tool life in demanding materials
• 3 right-hand helical flutes balance chip evacuation and cutting forces in internal thread milling
• Long-reach design provides access to deep or recessed threaded features
• Cuts M5 x 0.80 Metric Coarse internal threads with a 0.15-inch cutting diameter
• No coolant-through design; suitable for flood or external coolant delivery setups

Compatibility

Designed for CNC machining centers performing internal M5 x 0.80 Metric Coarse thread milling operations; accepts standard 1/4-inch collet or shrink-fit toolholders.

Installation Notes

Thread milling requires a CNC machine capable of helical interpolation; confirm control compatibility before programming. Secure the shank in a properly sized collet or shrink-fit holder and verify runout before cutting. Follow the tool manufacturer and machine builder guidelines for feed rate, stepover, and coolant strategy. Inspect the cutting edge for wear or chipping between operations to avoid thread-form errors.
