Product Description

The CLEVELAND C24262 is a No. 7 taper pin reamer designed for precision hole finishing, hole enlarging, and hole shaping in metalworking applications. Built from high-speed steel (HSS), this reamer produces accurate tapered holes to accept standard No. 7 taper pins. It features a straight flute geometry with 6 flutes and a right-hand cutting direction, delivering a controlled, smooth cut. The small end diameter measures 0.3297 inches and the large end diameter measures 0.422 inches, following a 1:48 taper rate. Overall length is 6.3125 inches with a flute length of 4.4375 inches. The 13/32-inch square shank provides positive drive in a manual or machine holder.

This reamer is suited for machine shops, maintenance facilities, and toolroom applications where taper pin holes must be cut or restored to precise dimensions. Typical workpiece materials include cast iron, steel, and steel alloy. The general-purpose performance rating makes it appropriate for production and repair work alike. It is sold individually and is part of the CLEVELAND Series 657 taper pin reamer line.

Installation Notes

This reamer is installed and operated by machinists or maintenance technicians using a manual tap wrench or machine spindle with a square-drive adapter. Always secure the workpiece firmly before reaming and use appropriate cutting fluid to extend tool life and improve surface finish. Power down and lock out any machine before changing or inspecting the reamer. Do not apply side pressure to the tool during operation, as taper reamers are designed for axial advancement only.
