Cleveland C24257 Taper Pin Reamer Size 2 Hss

Product Description

The CLEVELAND C24257 is a Number 2 taper pin reamer designed to enlarge, finish, and shape tapered holes to accept standard taper pins. Built from high-speed steel (HSS), it delivers consistent cutting performance across cast iron, steel, and steel alloy workpieces. The tool features 6 straight flutes with a bright/uncoated finish and a right-hand cutting direction. With a small end diameter of 0.1605 inches and a large end diameter of 0.2008 inches, it is precision-ground to a 1:48 taper rate. Machinists, tool-and-die workers, and maintenance technicians reach for this reamer when fitting taper pins in mechanical assemblies.

The C24257 is used in general-purpose machining and maintenance applications where a Number 2 taper pin hole must be precisely sized. It is suited for hand or machine reaming operations on cast iron, carbon steel, and alloy steel components. The 13/64-inch square shank (0.2031 inches) seats securely in a tap wrench or reamer driver for controlled material removal. Typical applications include gear hubs, shaft collars, couplings, and other assemblies where taper pins provide positive locking.

Key Features

• Number 2 taper pin size with a 1:48 taper rate for standard pin fitment
• High-speed steel construction for durability across ferrous workpiece materials
• 6 straight flutes provide smooth, consistent stock removal
• Bright/uncoated finish suitable for general-purpose reaming operations
• Right-hand cut with a square shank for use in standard tap wrenches and reamer drivers
• Flute length of 1.9375 inches provides adequate cutting surface for through-hole and blind-hole applications

Compatibility

Designed as a general-purpose taper pin reamer for Number 2 taper pin holes in cast iron, steel, and steel alloy workpieces requiring a 1:48 taper.

Installation Notes

This reamer is installed by machinists and maintenance technicians using a tap wrench or appropriate reamer driver. Secure the workpiece firmly before reaming to prevent movement and maintain hole alignment. Apply cutting fluid to extend tool life and improve surface finish when reaming steel or alloy materials. Never reverse the cutting direction while the tool is engaged in the hole, as this can damage the flute edges.
