  • 3750 in diameter matches standard thread-mill holders
  • Multi-point geometry reduces cycle time on CNC machines

Micro 100 Thread Mill .3750 in

The Micro 100 TM-375 is a single-profile thread mill built from solid carbide with a bright uncoated finish. It cuts UN threads in a 0.3750 in diameter and suits machinists who need a multi-point tool for hole, drill, bore and wire-gauge work. Buyers looking for coated geometries or larger diameters will need a different tool.

Thermals noise and power draw

Hand-operated cutting tools generate heat only at the workpiece interface and produce no electrical noise or power consumption. Standard shop coolant or lubrication manages temperature during threading operations. The carbide substrate resists wear under normal machining loads.

Accessories and software

The tool ships as a single unit with no bundled inserts, holders or software. Operators must supply their own tool-holding system and CAM programming. Free shipping applies on orders of 75 or more.

Questions about this item

How do you install the TM-375 thread mill and what step is often missed?

Mount the carbide tool in a rigid holder, verify the 0.3750 in diameter matches the programmed path, and apply coolant — skipping the coolant step causes premature wear on the uncoated flutes.

What maintenance or replacement will the TM-375 need over time?

The bright carbide cutting edges will dull; plan to resharpen or replace the tool once thread quality drops, as the uncoated surface offers no wear coating to extend life.

What limit appears first during sustained threading with the TM-375?

Heat buildup in the uncoated carbide flutes becomes the limiting factor, forcing reduced feed rates or pauses to prevent edge breakdown during long cycles.
