Cleveland C24272 Taper Pin Reamer Size 5/0 Hss

Product Description

The CLEVELAND C24272 is a taper pin reamer designed to enlarge, finish, and shape tapered holes to accept standard taper pins. Built from high-speed steel with a bright, uncoated finish, this tool delivers accurate material removal in cast iron, steel, and steel alloy workpieces. It features a 5/0 taper pin size with a small end diameter of 0.0719 inches and a large end diameter of 0.0966 inches, following a 1:48 taper rate. The four-flute, spiral-flute geometry with left-hand spiral and right-hand cut provides clean, controlled cutting action. Machinists and maintenance technicians in general manufacturing, machine shops, and industrial maintenance environments are the typical users.

This reamer is suited for general-purpose hole finishing and sizing work on cast iron, carbon steel, and steel alloy components where a precise tapered bore is required for taper pin fastening. The 7/64-inch square shank, measuring 0.1094 inches in decimal, seats in standard machine tool holders or hand braces. With an overall length of 2-3/16 inches and a flute length of 1-3/16 inches, the C24272 fits well in confined work areas and smaller part setups typical of maintenance and repair operations.
