Cleveland C24283 Taper Pin Reamer Size 7 Hss 6 Flutes

Product Description

The CLEVELAND C24283 is a Number 7 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to precise tolerances. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent performance in general-purpose machining applications. The reamer features 6 spiral flutes with a left-hand spiral direction and right-hand cutting action, which helps pull chips away from the cutting edge during operation. The small end diameter measures 0.3297 inches and the large end measures 0.422 inches, following a standard 1:48 taper rate. Licensed machinists and toolroom technicians are the primary installers of this tool.

This taper pin reamer is suited for use on cast iron, steel, and steel alloy workpieces in both production and toolroom environments. It is used wherever a tapered hole must be sized to accept a standard Number 7 taper pin for shaft-to-hub connections, clevis pins, or mechanical assemblies requiring a precise, removable interference fit. The square shank allows direct mounting in standard tap wrenches or adjustable holders for hand reaming operations.

Key Features

• Number 7 taper pin size with a 1:48 taper rate for standard taper pin fitment
• High-speed steel construction for general-purpose durability across ferrous workpiece materials
• 6 left-hand spiral flutes with right-hand cutting direction for efficient chip evacuation
• Bright, uncoated finish suitable for use with standard cutting fluids
• Square shank (0.4063 inches) for secure grip in tap wrenches or reamer drivers
• Overall length of 6.3125 inches with a flute length of 4.4375 inches for adequate reach in most setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for Number 7 taper pin reaming applications in cast iron, steel, and steel alloy workpieces where a 1:48 taper is required.

Installation Notes

This tool is intended for use by machinists and toolroom technicians familiar with hand or machine reaming procedures. Secure the workpiece fully before beginning the reaming operation and apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Always ream in the cutting direction only and avoid reversing the tool under load, as this can damage the flute edges. Inspect the shank seating in the driver or wrench before use to ensure concentricity and prevent chatter.
