Questions about this item

Does the TM-250-20X thread mill include any holders or collets, or must those be purchased separately?

The Micro 100 TM-250-20X is supplied as the helical-flute carbide thread mill only; tool holders, collets or arbors are not included and must be sourced separately to match your machine spindle.

How do I decide between the .1800 in diameter and other sizes in the TM-250 range?

Choose the .1800 in cutter when the thread specification calls for that exact minor diameter; the 20X flute length suits holes up to roughly 20 times the diameter, so match the tool to the thread size and depth your job requires.
