Cleveland C24263 Taper Pin Reamer Size 8 Hss

Product Description

The CLEVELAND C24263 is a straight-flute taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Built from high-speed steel (HSS), this reamer handles the repeated stress of production and maintenance work without losing its edge. It features a size 8 taper pin profile with a small end diameter of 0.3971 inches and a large end diameter of 0.505 inches, making it suitable for precise hole preparation where a secure, wedged pin fit is required. Machinists, toolroom technicians, and maintenance mechanics rely on this tool for accurate, repeatable results on ferrous and alloy workpieces.

The C24263 is suited for general-purpose hole finishing in cast iron, steel, and steel alloy materials. Common applications include fitting taper pins in shafts, collars, linkages, and mechanical assemblies where a removable but tight-fitting pin connection is needed. The right-hand cutting direction and straight flute geometry make it compatible with standard drill presses, lathes, and manual reaming setups. It is appropriate for both production shop and maintenance repair operations.

Key Features

• Size 8 taper pin profile with a 1:48 taper rate for standard taper pin fitment
• High-speed steel construction for durability across cast iron, steel, and steel alloy workpieces
• 6 straight flutes for consistent chip evacuation and smooth finish
• Bright/uncoated finish — ready for use with cutting fluid in standard reaming applications
• Square shank at 0.4375 inches for positive drive in tap wrenches and reaming fixtures
• Right-hand cutting direction compatible with standard machine and hand reaming setups

Compatibility

Designed as a general-purpose taper pin reamer for use in standard size 8 taper pin applications in cast iron, steel, and steel alloy workpieces.

Installation Notes

Taper pin reamers are installed and operated by machinists or maintenance technicians using a tap wrench, drill press, or lathe setup. Always secure the workpiece firmly before reaming, and apply a suitable cutting fluid throughout the operation to extend tool life and achieve the specified surface finish. Remove all chips frequently during the cut. Inspect the reamed hole for proper pin fit before driving the taper pin to final position.
