Value Collection SM24N07 Taper Pin Reamer Size 7 Hss

Product Description

The VALUE COLLECTION SM24N07 is a Size 7 taper pin reamer designed for hole enlarging, finishing, and shaping to precise tapered tolerances. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers general-purpose cutting performance in a variety of shop and field applications. The reamer has a small end diameter of 0.3297 inches and a large end diameter of 0.422 inches, with a taper rate of 1:48 per foot. The straight flute geometry and right-hand cutting direction make it compatible with standard drill press and hand-reaming setups. Overall length is 6.3125 inches with a flute length of 4.4375 inches. It weighs 0.09 pounds.

This reamer is suited for machinists, toolmakers, and maintenance technicians who need to produce or refine tapered pin holes in metal components. Taper pin reamers are commonly used in machine assembly, fixture building, and mechanical repair work where a tapered pin must seat precisely to secure mating parts. The Size 7 designation corresponds to standard taper pin sizing per American National Standards, making this tool appropriate for applications requiring consistent, repeatable taper geometry in carbon steel, alloy steel, aluminum, and similar machinable materials.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians using a drill press, milling machine, or hand-reaming setup. Secure the straight shank firmly in a chuck or reaming handle before use. Apply cutting fluid appropriate to the workpiece material to extend tool life and achieve proper surface finish. Never force the reamer through material; use steady, controlled feed pressure and back the tool out periodically to clear chips.
