Value Collection 556u 8 Taper Pin Reamer Size 8 Hss

Product Description

The VALUE COLLECTION 556u 8 is a straight-flute taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Built from high speed steel with a bright, uncoated finish, this reamer maintains edge integrity across general-purpose metalworking applications. The tool features a 0.3971-inch small end diameter and a 0.5050-inch large end diameter, producing the taper required for size 8 taper pins. With a 5.1875-inch flute length and a 7.1875-inch overall length, it provides adequate reach for typical benchtop and machine-shop setups. The square shank measures 0.4375 inches and is suited for standard drill press or lathe chuck mounting.

This taper pin reamer is used in machine shops, maintenance facilities, and manufacturing environments where taper pins are used to lock components such as gears, collars, and levers onto shafts. The right-hand cutting direction and straight flute geometry make it appropriate for hand reaming or slow-speed machine reaming in ferrous and non-ferrous materials. It is sized for size 8 taper pins following the standard 1:48 taper rate, which is common in general mechanical assembly and repair work.

Key Features

• High speed steel construction for durability across general-purpose reaming tasks
• Size 8 taper pin geometry with a 1:48 taper rate for standard taper pin fitment
• Straight flute design suited for hand reaming and low-speed machine reaming
• Right-hand cutting direction compatible with standard drill press and lathe setups
• Bright, uncoated finish — no additional coating to affect dimensional tolerance
• Square shank at 0.4375 inches for secure chuck engagement

Compatibility

Designed as a general-purpose replacement or production reamer for size 8 taper pin applications following the standard 1:48 taper rate used in mechanical assembly and repair.

Installation Notes

Taper pin reamers are typically used by machinists and maintenance technicians. Power down and lock out any machinery before reaming holes in installed components. Use cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Advance the reamer slowly and back it out periodically to clear chips and prevent tool chatter or taper distortion.
