Value Collection 556U6/0 Taper Pin Reamer Size 6/0 Hss

Product Description

The VALUE COLLECTION 556U6/0 is a straight-flute taper pin reamer designed for hole enlarging, finishing, and shaping operations in metalworking and machining applications. Manufactured from high-speed steel with a bright, uncoated finish, this reamer accepts a size 6/0 taper pin with a small end diameter of 0.0611 inches and a large end diameter of 0.0806 inches. The square shank measures 3/32 inches (0.0938 inches) in diameter, and the right-hand cutting direction is standard for conventional drilling setups. Overall length is 1-15/16 inches, with a flute length of 15/16 inches, making it suited for precision work in tight or confined bores.

This taper pin reamer is intended for general-purpose machining tasks where tapered holes must be accurately sized and finished to accept standard taper pins. Typical applications include fixture assembly, machine component alignment, and pin-hole preparation in small mechanical assemblies. The 6/0 size addresses some of the smallest taper pin requirements, making it appropriate for instrument work, toolmaking, and fine mechanical fabrication. It is used by machinists, tool-and-die makers, and maintenance technicians working with precision metal components.

Key Features

• High-speed steel construction for durability in general-purpose hole finishing operations
• Straight flute geometry suitable for standard taper pin hole sizing
• Size 6/0 taper pin compatibility with a 1:48 taper rate
• Right-hand cutting direction for conventional machine and hand use
• Square shank at 3/32 inches for positive drive in standard tap wrenches or chucks
• Bright, uncoated finish — no coating buildup to affect close-tolerance fits

Compatibility

Designed as a general-purpose replacement or service reamer for applications requiring a size 6/0 taper pin hole, conforming to a 1:48 taper rate standard.

Installation Notes

This reamer is installed and operated by machinists using a tap wrench, brace, or low-speed drill press — high spindle speeds are not appropriate for small taper reamers and can cause chatter or premature wear. Ensure the workpiece is securely fixtured and that the pilot hole is within the correct size range before reaming. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Always back the reamer out carefully and clear chips to prevent binding in the flutes.
