Micro 100 TM-500 Thread Mill 11-32 Tpi 5 Flute Solid Carbide

Product Description

The MICRO 100 TM-500 is a single profile thread mill designed for cutting both internal and external threads across a range from 11 to 32 threads per inch (TPI). Built from solid carbide, this tool delivers the rigidity and wear resistance required for precise thread milling in production and job-shop environments. The bright, uncoated finish suits a wide range of workpiece materials where coating adhesion or heat buildup is not a primary concern. With a 5/16-inch shank diameter and a 5-flute geometry, the TM-500 is suited for CNC machining centers running interpolated thread milling cycles.

This tool is applied in CNC milling operations where a single tool must cover multiple thread sizes without a tool change. The 11-32 TPI range covers a broad set of standard unified and other common thread forms for both through-hole and blind-hole applications. Internal thread milling on a helical path and external thread milling on cylindrical features are both within this tool's capability. Machinists and tooling specialists in aerospace, automotive, and general precision machining commonly select single profile thread mills for flexible, low-force threading operations.

Key Features

• Covers 11 to 32 TPI in a single tool, reducing tooling inventory for multi-pitch threading jobs
• Cuts both internal and external thread forms
• Solid carbide construction provides rigidity and extended tool life compared to HSS alternatives
• 5-flute design supports efficient chip evacuation and stable cutting action
• Bright, uncoated finish compatible with a wide range of workpiece materials
• 0.275-inch neck diameter provides clearance for thread milling at depth

Compatibility

Designed for use in CNC machining centers with helical interpolation capability and a 5/16-inch collet, end mill holder, or compatible toolholder accepting a straight shank.

Installation Notes

Thread milling with the TM-500 requires a CNC control capable of helical interpolation. Ensure the tool is seated securely in a low-runout holder, as excessive runout directly affects thread quality and tool life. Confirm spindle speed, feed rate, and helical pitch programmed in the CAM or G-code match the target thread specification before cutting. Follow shop safety procedures for CNC operation, including proper guarding and workpiece fixturing.
