Micro 100 TM-138-32X helical-flute thread mill .1000 in tubing

SKU CH-NFWP-5FG8T

Helical-flute carbide thread mill cuts UN threads in .1000 in tubing

  • C2 micrograin carbide resists wear during threading
  • AlTiN coating extends tool life in tough materials
  • Helical flute design improves chip evacuation while cutting
  • 32 flutes produce precise threads in .1000 in tubing

Micro 100 TM-138-32X helical-flute thread mill

The Micro 100 TM-138-32X is a solid-carbide thread mill with a helical flute design for cutting UN threads in a variety of workpiece materials. Its 0.1000 inch cutting diameter suits small-diameter internal threading operations where a tap would be prone to breakage. Machinists and tool-room engineers select this cutter for precision thread profiles in difficult-to-machine alloys.

C2 Micrograin Carbide substrate with AlTiN coating

The tool is ground from C2 Micrograin Carbide and coated with AlTiN for high hot-hardness and oxidation resistance at elevated cutting temperatures. This combination extends tool life in steels, stainless steels and high-temperature alloys. Shops that require uncoated carbide or a different substrate for non-ferrous materials will need an alternative cutter.

Questions about this item

What does the .1000 in diameter mean when the thread mill is in the machine?

The .1000 in cutting diameter determines the smallest thread size the tool can produce; it engages the workpiece at that exact width so the programmed tool path must match this dimension for accurate thread forms.

How does the helical flute design affect chip evacuation in practice?

The helical flute geometry lifts chips upward and out of the cut while the tool interpolates, reducing re-cutting and heat buildup in deep or blind holes compared with straight-flute alternatives.
