Value Collection ATR2607 Taper Pin Reamer 2/0 Hss

Product Description

The VALUE COLLECTION ATR2607 is a taper pin reamer designed for enlarging, finishing, and shaping holes to accept standard taper pins. Made from high-speed steel (HSS), this reamer features a helical flute geometry with a right-hand cut and left-hand spiral direction, which helps pull chips away from the cutting zone during operation. The small end diameter is 0.1137 inches and the large end diameter is 0.1462 inches, conforming to the 2/0 taper pin size standard at a 1:48 taper rate. The bright, uncoated finish is suitable for general-purpose use across a wide range of workpiece materials. Machinists and toolroom technicians use this reamer to produce accurate, repeatable taper pin holes in metal components.

This reamer is suited for general-purpose hole finishing and shaping operations on the bench or in a machine shop environment. It is commonly used when assembling mechanical components that rely on taper pins for shaft-to-hub connections, linkages, or alignment fixtures. The 2/0 size is a small-diameter application, making it appropriate for precision assemblies in light machinery, instrumentation, and similar fabrication work. The straight shank accepts standard drill chucks or collet holders, giving it broad machine compatibility.

Key Features

• High-speed steel construction for durability in general-purpose metal reaming applications
• Helical flute geometry with left-hand spiral and right-hand cut for efficient chip evacuation
• 2/0 taper pin size with a 1:48 taper rate for standardized pin hole fitting
• Bright, uncoated finish compatible with a wide range of workpiece materials
• Straight shank at 0.1563 inches diameter fits standard chucks and collet holders
• Compact overall length of 2.5625 inches suits tight-clearance setups

Compatibility

Designed as an OEM-style replacement or direct-use reamer for applications requiring a standard 2/0 taper pin hole in general-purpose machining and assembly operations.

Installation Notes

This tool is installed and used by machinists, toolroom technicians, and precision assemblers. Always secure the workpiece and ensure the reamer is properly seated in the chuck or collet before operation. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Do not force the reamer — light, steady feed pressure prevents chatter and premature wear.
