AYSNAGSDHSS Standard Drill 520P GSDSold0pcsNACHI 520P GSD is the TiN coated straight shank drill in standard length. TiN is the sweet spot between life and price - longer lasting than 500 SD and cheaper than cobalt; for heavy stainless work 6520 COSD is still the better call. It is made from plain high speed steel with NACHI's G coating, a TiN-based general-purpose layer with excellent adhesion to HSS. Sizes cover diameter 0.5~13mm, flute length 6~101mm, overall length 22~151mm, 126 in total, made in Japan. When is the coating worth paying for? On lines where tool changes are frequent or downtime costs more than the tool. It suits carbon and alloy steel, stainless steel with workpiece hardness up to HRC30. Typical uses: general steel drilling, production work, and jobs where longer intervals between tool changes are wanted. The family also includes the stub 6568P GSS (flute length 8~94mm, HRC40) and the long 6550P GLSD (flute length 40~150mm, HRC40); the uncoated baseline is 500 SD, covering diameter 0.2~17.5mm.
