Value Collection SM25N06 Taper Pin Reamer No 6 Hss

Product Description

The VALUE COLLECTION SM25N06 is a No. 6 taper pin reamer ground from high-speed steel for hole enlarging, hole finishing, and hole shaping operations. It produces accurately tapered holes to accept No. 6 taper pins in metal assemblies. The spiral flute geometry with right-hand cutting action and left-hand spiral promotes chip evacuation during through-hole reaming. With a 5-7/16-inch overall length and a 3-11/16-inch flute length, this reamer handles standard workpiece thicknesses encountered in general-purpose machining and repair work. Machinists, toolroom technicians, and maintenance mechanics are the primary users.

This reamer is suited for general-purpose metalworking applications where a No. 6 tapered hole must be produced or reconditioned to accept a standard taper pin. Typical scenarios include shaft-to-hub pinning, linkage assemblies, and precision alignment fixtures in manufacturing and maintenance environments. The straight shank with a 23/64-inch diameter seats in standard drill press chucks, milling machine collets, and hand-held tapping handles, making it adaptable to both machine and hand reaming setups.

Key Features

• No. 6 taper pin size with a 1:48 taper rate for standard taper pin fitment
• High-speed steel construction for durability across ferrous and non-ferrous materials
• Spiral flute with left-hand spiral and right-hand cut for effective chip evacuation
• Bright/uncoated finish — no coating buildup to affect dimensional accuracy
• Straight shank at 23/64 inches diameter fits standard chucks and collets
• General-purpose performance rating suitable for production and maintenance use

Compatibility

Designed as an OEM-style replacement and general-purpose reamer for applications requiring a No. 6 taper pin hole with a 1:48 taper rate, a small end diameter of 0.2773 inches, and a large end diameter of 0.3540 inches.

Installation Notes

Machinists and maintenance technicians should secure the workpiece fully before reaming and ensure the starting hole is pre-drilled to the appropriate undersize. Power down and de-energize any equipment before reaming pinned assemblies on installed machinery. Use cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Follow shop safety practices and applicable OSHA standards when operating drill presses or milling equipment.
