Value Collection SM25N00 Taper Pin Reamer Size 0 Hss

Product Description

The VALUE COLLECTION SM25N00 is a Size 0 taper pin reamer designed for hole enlarging, hole finishing, and hole shaping operations in precision machining and mechanical assembly work. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it features a small end diameter of 0.1287 inches and a large end diameter of 0.1638 inches. The spiral flute geometry with a right-hand cut and left-hand spiral direction helps evacuate chips efficiently during through-hole reaming passes. This tool is used by machinists and tool-and-die professionals working to size tapered holes for standard taper pin fasteners.

This reamer is suited for general-purpose bench work, drill press operations, and manual or CNC applications where a Size 0 taper pin fit is required. Typical use cases include sizing holes in mechanical linkages, shafts, and assemblies that retain components with taper pin fasteners. The straight shank allows direct chuck mounting. The 1.6875-inch flute length accommodates most standard taper pin hole depths encountered in light to medium metalworking applications.

Key Features

• High-speed steel construction for durability across ferrous and non-ferrous materials
• Spiral flute design promotes efficient chip evacuation during reaming
• Right-hand cutting direction with left-hand spiral for controlled material removal
• Bright, uncoated finish suitable for general-purpose use without added coating cost
• Straight shank at 0.1719 inches diameter fits standard drill chucks and collets
• Taper rate of 1:48 matches ASME standard taper pin geometry for Size 0

Compatibility

Designed as an OEM-style replacement or standard tooling option for Size 0 taper pin reaming applications in general-purpose machining and mechanical assembly environments.

Installation Notes

Installation should be performed by a qualified machinist or tooling professional using a drill press, lathe, or appropriate hand reaming setup. Secure the workpiece firmly before reaming and apply cutting fluid to extend tool life and improve finish quality. Always ream to final size in incremental passes rather than removing full stock in a single pass. Follow applicable shop safety standards and wear appropriate personal protective equipment when operating cutting tools.
