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. During the drilling process, it is not allowed to turn back the\ndrill bit to avoid damaging the cutting edge.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eA set of 15 hand-used reamers, including 15 different diameters ranging from 3 to 12 millimeters and radius sizes such as 4.5 and 5.5, featuring H8 tolerance grade\u003c\/li\u003e\n         \u003cli\u003eConstructed from alloy steel, heat-treated for good wear tolerance suitable for general hand reaming applications\u003c\/li\u003e\n         \u003cli\u003eStraight flute design allows smooth debris removal, suitable for both through holes and blind holes for hand use\u003c\/li\u003e\n         \u003cli\u003eFour-sided end shank fits reamer wrenches, providing better command and leverage during manual use\u003c\/li\u003e\n         \u003cli\u003eBefore use, pre-drill holes with 0.10.3mm allowance.
