{"product_id":"endmill-onsrud-56-310","title":"LMT Onsrud 56-310 5\/16\" Solid Carbide 2-Flute Straight V-Flute Router Bit for Wood – 1-1\/8\" Cut Length, 1\/2\" Shank, 3\" OAL","description":"\u003cp\u003eThe LMT Onsrud 56-310 is a 5\/16\" solid carbide, two-flute straight V-flute router bit from Onsrud's 56-300 wood series, ground for a superior finish and long cutter life in hardwood, softwood, and wood composites. A straight flute cuts with no upward or downward pull on the material, which makes it the right choice for dadoes, grooves, mortises, and inlay pockets where you want a flat, clean floor and crisp walls without lifting veneer or fuzzing the top edge. The heavy 1\/2\" shank behind a 5\/16\" cutting diameter gives this bit far more rigidity than a 5\/16\"-shank tool, so it holds size on deep passes and resists deflection on long cuts.\u003c\/p\u003e\n\u003ch2\u003eLMT Onsrud 56-310 specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003ePart number\u003c\/th\u003e\n\u003ctd\u003e56-310 (LMT Onsrud 56-300 series)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCutting diameter\u003c\/th\u003e\n\u003ctd\u003e5\/16\" (0.3125\", 7.94 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCut length (LOC)\u003c\/th\u003e\n\u003ctd\u003e1-1\/8\" (1.125\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eShank diameter\u003c\/th\u003e\n\u003ctd\u003e1\/2\" (0.500\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOverall length\u003c\/th\u003e\n\u003ctd\u003e3\" (3.000\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFlutes\u003c\/th\u003e\n\u003ctd\u003e2, double edge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFlute type\u003c\/th\u003e\n\u003ctd\u003eStraight V-flute (no helix)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMaterial\u003c\/th\u003e\n\u003ctd\u003eSolid carbide, uncoated (bright) finish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCountry of origin\u003c\/th\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUPC\u003c\/th\u003e\n\u003ctd\u003e895680009951\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eWhat the 56-310 is designed to cut\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHardwoods such as oak, maple, walnut, and cherry\u003c\/li\u003e\n\u003cli\u003eSoftwoods and plywood\u003c\/li\u003e\n\u003cli\u003eMDF, particleboard, and laminated wood composites\u003c\/li\u003e\n\u003cli\u003eVeneered and melamine-faced panels where edge chipping must be minimized\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eStraight flute vs. spiral: when to pick this bit\u003c\/h2\u003e\n\u003cp\u003eA spiral upcut pulls chips out of the cut but can tear the top edge; a downcut leaves a clean top but packs chips into a deep slot. A straight V-flute does neither. It shears the material cleanly on both edges, which is why straight-flute carbide bits remain the standard for grooving, dadoes, and inlay work in cabinet shops. Keep passes shallower than you would with a spiral and let dust collection do the chip clearing.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003eThe 1\/2\" shank requires a 1\/2\" collet: ER20, ER25, ER32, or a 1\/2\" collet on a full-size router. It will not fit 1\/4\"-collet trim routers or ER11\/ER16 spindles. The 5\/16\" cutting diameter is a direct match for 5\/16\" hardware slots, 8 mm-class dadoes, and standard shelf-pin and T-track grooves.\u003c\/p\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWhy is the shank bigger than the cutting diameter?\u003c\/strong\u003e\u003cbr\u003eRigidity.
