Value Collection 558u 9 Taper Pin Reamer Size 9 Hss

Product Description

The VALUE COLLECTION 558u 9 is a Size 9 taper pin reamer designed for enlarging, finishing, and shaping tapered holes to accept standard taper pins. Machined from high speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent material removal in general-purpose shop and maintenance applications. The helical flute geometry promotes smooth cutting action and efficient chip evacuation. With a small end diameter of 0.4805 inches, a large end diameter of 0.6066 inches, and a taper rate of 1:48, this tool produces holes sized precisely for Size 9 taper pins. Right-hand cutting direction with a left-hand spiral is standard for this reamer style.

This reamer is used in machine shops, maintenance facilities, and manufacturing environments wherever tapered pin connections are required in mechanical assemblies. Typical applications include fitting shafts, hubs, collars, and couplings that rely on taper pins for alignment and retention. The straight shank suits standard drill press chucks and milling machine collets, making setup straightforward in most shop environments.

Key Features

• Size 9 taper pin geometry with a 1:48 taper rate for accurate pin-hole fit
• High speed steel construction for durability across a range of workpiece materials
• Helical flute design for smooth cutting and efficient chip removal
• Bright, uncoated finish — no coating to interfere with close-tolerance work
• Right-hand cut with left-hand spiral, consistent with standard taper pin reamer practice
• Straight shank at 0.5625 inches diameter for use in chucks and collets

Compatibility

Designed as an OEM-style replacement and general-purpose taper pin reamer sized for Size 9 taper pin applications in standard 1:48 taper pin hole finishing operations.

Installation Notes

Taper pin reamers are typically used by machinists and maintenance technicians in drill press, milling machine, or lathe setups. Secure the workpiece firmly before reaming and use appropriate cutting fluid to extend tool life and improve finish quality. Advance the reamer gradually and avoid excessive feed pressure, which can deflect the tool or cause chatter. Always verify hole size with the mating taper pin before final assembly.
