Machined from high-speed steel (HSS) with a bright\/uncoated finish, it features a spiral flute geometry with a right-hand cutting direction and left-hand spiral for smooth chip evacuation. The small end diameter is 0.3297 inches and the large end diameter is 0.4220 inches, following a 1:48 taper rate. Overall length is 6.3125 inches with a 4.4375-inch flute length and a straight shank measuring 0.4063 inches in diameter. This reamer is suited for general-purpose use in machine shops, maintenance environments, and production settings.\u003c\/p\u003e\n\u003cp\u003eThe SM25N07 is used wherever No. 7 taper pins must be seated accurately in shafts, hubs, and mechanical assemblies. Typical applications include hole finishing in steel, aluminum, and other machinable metals where a precise tapered bore is required prior to pin installation. It is appropriate for manual or machine-driven use in general manufacturing, toolroom, and repair applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 7 taper pin size with a 1:48 taper rate for accurate pin fitment\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a range of machinable materials\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design promotes smooth chip removal during cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with left-hand spiral for reduced chatter and clean finish\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose hole finishing\u003c\/li\u003e\n  \u003cli\u003eStraight shank compatible with standard chucks and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose No. 7 taper pin reamer for use in standard drill presses, milling machines, or hand-held drilling equipment with a compatible straight-shank chuck.
