Cleveland C24237 Taper Pin Reamer No. 2 Hss

Product Description

The CLEVELAND C24237 is a No. 2 taper pin reamer manufactured from high-speed steel (HSS) for hole enlarging, finishing, and shaping operations. It features a helical flute geometry with a right-hand cutting direction and left-hand spiral, which helps pull chips away from the workpiece during cutting. The small end diameter is 0.1605 inches and the large end diameter is 0.2008 inches, with a taper rate of 1:48. The straight shank measures 0.2031 inches in diameter. Machinists and tool and die technicians use this reamer to accurately size taper pin holes in precision assemblies.

This reamer is suited for general-purpose material removal on aluminum, steel, and steel alloy workpieces in both production and maintenance environments. The bright, uncoated finish allows the user to inspect the cutting edges easily and is appropriate for use with cutting fluids or dry. Typical applications include sizing taper pin bores in shafts, hubs, and mechanical assemblies where a precise interference fit is required between the pin and the bore.

Key Features

• No. 2 taper pin size with a 1:48 taper rate for standard taper pin hole sizing
• High-speed steel construction for durability across aluminum, steel, and steel alloy workpieces
• Helical flute with left-hand spiral promotes chip evacuation during right-hand cutting
• Bright/uncoated finish compatible with cutting fluids and dry machining
• Straight shank at 0.2031 inches diameter for standard collet or drill chuck mounting
• General-purpose tool performance suitable for hole enlarging, finishing, and shaping

Compatibility

Designed as an OEM-style taper pin reamer for use in standard No. 2 taper pin applications across a range of metalworking and mechanical assembly setups.

Installation Notes

This reamer should be installed and operated by a qualified machinist familiar with rotary cutting tools and proper speeds and feeds for the workpiece material. Secure the straight shank firmly in a collet, drill chuck, or reamer holder before use, and verify the setup is rigid to prevent chatter. Always reduce spindle speed compared to a twist drill of similar diameter, and apply cutting fluid when reaming steel or steel alloy materials. Follow applicable shop safety procedures and wear appropriate eye protection during all reaming operations.
