Cleveland C24244 Taper Pin Reamer Size 9 Hss

Product Description

The CLEVELAND C24244 is a Size 9 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to precise dimensional tolerances. Manufactured from high-speed steel (HSS), this reamer features a helical flute geometry with a right-hand cut and left-hand spiral direction, which reduces chatter and produces a smoother finished bore. The small end diameter measures 0.4805 inches and the large end measures 0.6066 inches, conforming to the standard 1:48 taper rate used for taper pin applications. It carries a bright uncoated finish and is built for general-purpose performance across a range of workpiece materials.

This reamer is suited for machine shops, maintenance facilities, and production environments where taper pin holes must be accurately sized or refinished. It is appropriate for use in both manual and machine setups and works with aluminum, steel, and steel alloy workpieces. The straight shank allows chucking in standard drill chucks or collet holders. Typical applications include shaft-to-hub taper pin fitting, fixture assembly, and precision hole finishing in metal fabrication and mechanical maintenance work.

Key Features

Installation Notes

Taper pin reamers should be installed by a qualified machinist or maintenance technician. Secure the workpiece firmly before operation and use appropriate cutting fluid to extend tool life and improve finish quality. Confirm spindle speed and feed rate are appropriate for the workpiece material before beginning. Always power down and de-energize the machine before changing tooling.
