Value Collection ATR2604 Taper Pin Reamer 5/0 Hss

Product Description

The VALUE COLLECTION ATR2604 is a taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Made from high speed steel with a bright, uncoated finish, this reamer handles general-purpose hole finishing in metal fabrication, machining, and assembly work. It carries a 5/0 taper pin size with a small end diameter of 0.0719 inches and a large end diameter of 0.0966 inches. The helical flute geometry promotes smooth cutting action and efficient chip evacuation. The straight shank seats securely in standard drill chucks or collet holders for consistent, repeatable results.

This reamer is suited for machine shops, maintenance and repair operations, and production environments where precise tapered holes are required. The right-hand cutting direction and left-hand spiral flute combination is standard for taper pin work, helping pull the tool into the workpiece for controlled material removal. Typical applications include fitting taper pins in shafts, hubs, and mechanical assemblies across general industrial and toolroom settings.

Key Features

• High speed steel construction provides durability across a range of ferrous and non-ferrous workpiece materials
• Helical flute design promotes efficient chip removal and smooth hole finish
• Right-hand cutting direction with left-hand spiral for controlled feed during taper pin reaming
• Bright, uncoated finish suitable for general-purpose use with standard cutting fluids
• Straight shank compatible with standard drill chucks and collet holders
• 1:48 taper rate matches the American Standard taper pin specification for 5/0 pin size

Compatibility

Designed as an OEM-style replacement or standard tooling option for applications requiring a 5/0 taper pin reamer with a 1:48 taper rate in general-purpose machining and assembly operations.

Installation Notes

This reamer is installed and operated by machinists and toolroom technicians using a drill press, milling machine, or hand-held drilling equipment. Secure the straight shank firmly in the chuck or collet before use, and apply appropriate cutting fluid to extend tool life and improve finish quality. Always ream at reduced RPM compared to standard twist drills, and advance the tool steadily without excessive force to avoid bell-mouthing the hole. Power down the machine completely before changing or inspecting the reamer.
