Value Collection 558u 0 Taper Pin Reamer No. 0 Hss

Product Description

The VALUE COLLECTION 558u 0 is a No. 0 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Built from high speed steel (HSS) with a bright/uncoated finish, this reamer delivers consistent material removal in general-purpose machining applications. It features a helical flute design with right-hand cutting action and a straight shank for secure chuck mounting. The small end diameter measures 0.1287 inches and the large end measures 0.1638 inches, conforming to the standard 1:48 taper rate used in taper pin applications.

This reamer is suited for machine shops, tool rooms, and maintenance environments where taper pin holes must be accurately sized or refinished. It is appropriate for use in metalworking operations on ferrous and non-ferrous materials requiring hole finishing to tight dimensional tolerances. The No. 0 size serves smaller-diameter taper pin installations common in shafts, levers, and mechanical assemblies. A licensed machinist or skilled maintenance mechanic typically performs this work.

Key Features

• High speed steel construction for general-purpose cutting performance
• Helical flute geometry promotes smooth chip evacuation during reaming
• Right-hand cutting direction with standard straight shank for lathe or drill press use
• 1:48 taper rate conforms to standard taper pin specifications
• Bright/uncoated finish suitable for use with cutting fluid
• Overall length of 2.9375 inches with a 1.6875-inch flute length for controlled cut depth

Compatibility

Designed as a general-purpose replacement or standard taper pin reamer for No. 0 taper pin holes conforming to the 1:48 taper standard in metalworking and maintenance machining applications.

Installation Notes

Secure the workpiece and ensure the spindle is properly aligned before reaming to avoid bell-mouthing the hole. Power down all equipment before changing or inspecting reamers. Use an appropriate cutting fluid to extend tool life and improve surface finish. This tool should be operated by a qualified machinist following applicable shop safety procedures.
