Its cutting edge is smooth and the size is\nstable. The fifteen-piece set includes fifteen nominal diameters ranging from\n3 to 12 millimeters, including 4.5 and 5.5 radius sizes, which can meet the\nrequirements for increasingly precise hole processing. The H8 tolerance grade\nis suitable for conventional precision hole processing contexts. The straight\nflute design is suitable for both through-hole and blind-hole hand drilling,\nfeaturing smooth debris removal. The four-sided tail handle can be used in\nconjunction with a drill bit handle for easier use. The use is force-saving\nand controllable. Before drilling the hole, a bottom hole should be pre-\ndrilled and a 0.1–0.3mm allowance should be left. When using, keep the drill\nbit concentric with the hole, rotate it at a uniform speed for feed, and use\ncutting fluid.
