Cleveland C24240 No. 5 Taper Pin Reamer High Speed Steel

Product Description

The CLEVELAND C24240 is a No. 5 taper pin reamer designed for precision hole finishing, enlarging, and shaping in metalworking applications. Manufactured from high-speed steel (HSS), this reamer features a helical flute geometry with a right-hand cutting direction and left-hand spiral. The small end diameter is 0.2409 inches and the large end diameter is 0.2994 inches, conforming to a 1:48 taper rate standard for No. 5 taper pins. Overall length is 4.3125 inches with a flute length of 2.8125 inches. The straight shank measures 0.3125 inches in diameter. This tool is installed and used by machinists, millwrights, and tool-and-die technicians working in precision assembly and repair environments.

The C24240 is suited for general-purpose reaming operations in production and maintenance settings. It is appropriate for use on aluminum, steel, and steel alloy workpieces where taper pin holes must be finished to close tolerances. The 1:48 taper conforms to the standard taper pin specification, making this reamer a direct-fit tool for preparing holes that receive No. 5 taper pins in mechanical assemblies, shafts, and fixtures. The bright uncoated finish is compatible with standard cutting fluids used in shop environments.

Installation Notes

This reamer is intended for use by machinists and skilled tradespeople in manual or machine reaming operations. Secure the straight shank firmly in a suitable chuck or collet before use, and ensure the workpiece is properly fixtured to prevent movement. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality. Always power down or de-energize the machine spindle fully before mounting or removing the reamer.
