Cleveland C24282 Taper Pin Reamer No. 6 Hss

Product Description

The CLEVELAND C24282 is a No. 6 taper pin reamer designed for precision hole finishing, enlarging, and shaping of taper pin seats. Manufactured from high-speed steel (HSS), it delivers consistent cutting performance across cast iron, steel, and steel alloy workpieces. The reamer features 6 spiral flutes with a right-hand cut and left-hand spiral direction, which pulls chips away from the finished bore during the cut. Overall length is 5.4375 inches with a flute length of 3.6875 inches, making it well suited for standard depth taper pin applications in toolrooms, machine shops, and maintenance environments.

This reamer is used to finish-ream taper pin holes to the No. 6 taper pin standard, with a small end diameter of 0.2773 inches and a large end diameter of 0.3540 inches at a 1:48 taper rate. It is appropriate for general-purpose material removal on ferrous workpieces in both production and repair settings. Machinists, tool-and-die makers, and maintenance technicians use this tool when fitting taper pins into shafts, hubs, and machine components where a precise, interference-fit bore is required.

Installation Notes

This tool is typically used by machinists and maintenance technicians with a hand tap wrench or in a manual or CNC drill press at controlled low speeds. Always secure the workpiece fully before reaming and apply cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Do not force the reamer; apply steady, even pressure and back the tool out periodically to clear chips. Follow applicable shop safety and OSHA machine guarding standards when operating.
