The helical flute geometry carries chips back toward the shank and out of enclosed holes, helping reduce chip accumulation around the cutting edges. A nitrided surface treatment increases surface hardness and wear resistance without changing the basic toughness of the HSS substrate. The listed range covers 14 metric coarse-thread sizes for CNC, tapping-center and general machine-tapping applications.<\/p>\n<p><!-- PRODUCT SUMMARY --><\/p>\n<div style=\"display: flex; flex-wrap: wrap;
