Micro 100 LTR-250-16 Thread Relief Tool Solid Carbide

Product Description

The MICRO 100 LTR-250-16 is a solid carbide thread relief tool designed for undercutting and relief groove operations on threaded workpieces. It removes material at the thread runout zone to create a clean relief that allows mating components to seat fully without interference. Machinists and toolroom operators use this tool on CNC lathes and manual turning centers. The cutting diameter measures 0.25 inches, the overall length is 2.5 inches, and the flat width is 0.094 inches, making it well suited for precision internal and external thread relief applications in production and job-shop environments.

This thread relief tool is used in machining operations where a defined undercut at the base of a thread form is required. Typical applications include shaft turning, threaded bore preparation, and component finishing in aerospace, medical device, and general precision machining. The 0.25-inch shank diameter fits standard ER and collet-style toolholders commonly found on CNC turning equipment. The 1-inch cutting depth provides clearance for deep-reach relief work without requiring extended-reach adapters in most standard setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 0.25-inch cutting diameter suits small-diameter thread relief applications
• 0.094-inch flat width for precise groove width control at thread runout
• 0.05-inch projection limits deflection and supports accurate depth control
• 1-inch cutting depth accommodates standard thread relief reach requirements
• 2.5-inch overall length compatible with standard collet toolholding systems

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC and manual lathes accepting a 0.25-inch shank diameter thread relief tool.

Installation Notes

Thread relief tools are installed and set up by qualified machinists. Power down and lock out the spindle before inserting or removing the tool from the holder. Seat the shank fully in the collet or toolholder and verify tool runout before cutting. Follow shop-standard feeds, speeds, and coolant procedures appropriate to the workpiece material and machine type.
