Cleveland C24258 Taper Pin Reamer Size 3 Hss 6 Flute

Product Description

The CLEVELAND C24258 is a Number 3 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Built from high-speed steel (HSS) with a bright/uncoated finish, it delivers consistent material removal in general-purpose machining applications. The reamer features 6 straight flutes, a right-hand cutting direction, and a 1:48 taper rate that matches the standard taper pin geometry. The square shank measures 0.2344 inches in diameter, the flute length is 2.3125 inches, and the overall length is 3.6875 inches. It is sized for use in drill presses, milling machines, and lathes by machinists and toolroom technicians.

This reamer is suited for production and maintenance work in machine shops, fabrication facilities, and toolrooms. It is used to finish taper pin holes in assemblies where a precise, interference-fit pin connection is required. Primary workpiece materials include cast iron, steel, and steel alloy. The general-purpose performance rating makes it appropriate for both prototype work and repeat production runs where tight hole tolerances are needed.

Installation Notes

This reamer is installed and operated by machinists using a drill press, lathe, or milling machine. Power down and lock out all equipment before securing the reamer in the holder. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the reamer for wear or chipping before each use and replace if cutting edges are damaged.
