This is a new Seco Tools S638R-0.500-D1-R030.0-Z6 solid caroffere square end mill in the 5000 series, part number 6151936 (variant 511), manufactured in the USA. Decoding the MPN: S638R = square-end, 6-flute, 38° helix, right-hand cut; 0.500 = 1/2 in (12.70 mm) cutting diameter; D1 = 1/2 in shank diameter; R030.0 = 0.030 in corner radius on each cutting edge; Z6 = 6 flutes. The HTA designation identifies the coating as Seco's HTA (High-Temperature AlTiN-based) PVD coating, which provides exceptional hardness and heat resistance for machining hardened steels, stainless steels, titanium alloys, and other difficult-to-machine materials. Overall length is 3 in with a 1-1/4 in length of cut, as confirmed by the "CARB 1/2×1/2×1-1/4×3" label text; the 38° variable helix geometry reduces chatter and improves surface finish in aggressive side-milling, slotting, and contouring operations. Compatible with standard 1/2 in ER, side-lock, hydraulic, or shrink-fit toolholders.
