Cleveland C24281 Taper Pin Reamer Size 5 Hss 6 Flute

Product Description

The CLEVELAND C24281 is a size 5 taper pin reamer designed for precision hole finishing, enlarging, and shaping in ferrous materials. Built from high-speed steel, this reamer features a spiral flute geometry with a right-hand cut and left-hand spiral, a combination that reduces chatter and produces a smoother finish in the bore. It carries a bright, uncoated finish suited for general-purpose work. With a flute length of 2.8125 inches and an overall length of 4.3125 inches, the C24281 is sized for typical bench and machine tool setups. Machinists and maintenance technicians in metalworking, industrial maintenance, and manufacturing environments use this tool for fitting taper pins to size in assembled components.

The C24281 is applied where a size 5 taper pin hole must be finished or reamed to final dimension. The 1:48 taper rate matches the standard taper pin specification. Primary workpiece materials include cast iron, steel, and steel alloy. The tool is suited for use in drill presses, manual lathes, or handheld setups where a square shank drive arrangement is required. This is a general-purpose reamer appropriate for production runs and repair work requiring consistent taper pin fitment.

Key Features

• Size 5 taper pin geometry with a 1:48 taper rate for standard taper pin fitment
• High-speed steel construction for durability in cast iron, steel, and steel alloy workpieces
• 6 spiral flutes with right-hand cut and left-hand spiral direction to reduce chatter and improve finish quality
• Square shank for positive drive in standard holders and chuck setups
• Bright, uncoated finish — no coating buildup concerns in close-tolerance applications
• General-purpose Series 659 tool suitable for hole enlarging, finishing, and shaping operations

Compatibility

Designed as an OEM-specification replacement or new-installation taper pin reamer for size 5 taper pin applications in cast iron, steel, and steel alloy workpieces following standard 1:48 taper pin geometry.

Installation Notes

This tool is installed and operated by machinists or qualified maintenance technicians using standard machine tool practices. Before use, secure the workpiece and ensure the square shank is fully seated in the drive holder. Use cutting fluid appropriate for the workpiece material to extend tool life and improve bore finish. Do not force the reamer through undersized stock in a single pass — step up progressively to avoid tool deflection or workpiece damage.
