Internal Tool 01-9039 .375x.180 .050/.025 RAD Solid Carbide Form Cutter

The Internal Tool 01-9039 is a new, USA-made solid carbide special-form cutter with a 3/8 in (0.375 in) shank diameter, 0.180 in cutter width, 13° rake angle, and dual corner radii of 0.050 in (top) and 0.025 in (bottom), making it a precision T-slot or undercut profile tool ground to a custom form geometry. Constructed from solid micrograin carbide throughout, it delivers superior rigidity, edge retention, and dimensional accuracy compared to HSS equivalents, and is suited for profiling undercuts, T-slots, and custom form features in steel, stainless, aluminum, and non-ferrous alloys on CNC machining centers and manual mills. The uncoated bright finish is visible in the photos and confirms this is a bare carbide tool; the 3/8 in straight shank is compatible with standard ER, Weldon, or shrink-fit toolholders of the same bore. Labeled "SPECIAL" on the factory packaging, this is a non-catalog custom-ground geometry produced to order by Internal Tool Inc., verified by the part number and label photography.
