Built from high speed steel with a bright, uncoated finish, this tool delivers general-purpose performance in metal fabrication, machining, and assembly applications. It is sized for a 4\/0 taper pin, with a small end diameter of 0.0869 inches and a large end diameter of 0.1142 inches. The helical flute geometry and right-hand cutting direction promote smooth material removal and accurate hole sizing. Overall length is 2.3125 inches with a 1.3125-inch flute length and a straight shank measuring 0.125 inches in diameter.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for use in machine shops, toolrooms, and assembly operations where taper pin holes must be precisely sized to ensure secure, repeatable fits. The 1:48 taper rate conforms to standard taper pin specifications, making this tool appropriate for creating or refinishing taper pin holes in shafts, hubs, collars, and similar mechanical components. It is commonly used by machinists and tool-and-die technicians working on both new builds and repair work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction for durability across a range of general-purpose machining tasks\u003c\/li\u003e\n\u003cli\u003eHelical flute design promotes smooth cutting action and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with left-hand spiral for reduced chatter and improved surface finish\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluids or dry in softer materials\u003c\/li\u003e\n\u003cli\u003eStraight shank at 0.125 inches fits standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eConforms to 1:48 taper rate standard for 4\/0 taper pin hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and general-purpose taper pin reamer for use in applications requiring a 4\/0 standard taper pin fit at a 1:48 taper rate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is typically used by machinists in manual or CNC-assisted operations.
