Value Collection 558u 6 Taper Pin Reamer No. 6 Hss

Product Description

The VALUE COLLECTION 558u 6 is a No. 6 taper pin reamer designed to enlarge, finish, and shape tapered holes to accept standard taper pins. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent cutting performance in general-purpose machining applications. The helical flute geometry promotes smooth chip evacuation and reduces chatter during the cut. The small end diameter measures 0.2773 inches, the large end measures 0.354 inches, and the overall length is 5.4375 inches. Licensed machinists and tool-and-die technicians use this reamer to produce precision-fit taper pin holes in shafts, hubs, and mechanical assemblies.

This reamer is suited for job shops, maintenance operations, and production environments where taper pin connections are used to secure components on shafts or align mating parts. The right-hand cutting direction pairs with a left-hand spiral flute to pull chips away from the work and improve surface finish in through-hole applications. It is appropriate for use in drill presses, lathes, and hand-held applications where controlled feed rates can be maintained.

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 a range of ferrous and non-ferrous materials
• Helical flute design promotes chip clearance and reduces cutting force
• Right-hand cutting direction with left-hand spiral for improved surface finish
• Bright, uncoated finish suitable for use with cutting oils and standard coolants
• Straight shank for easy chuck mounting on standard machine tools

Compatibility

Designed as an OEM-style replacement and standard tooling option for applications requiring No. 6 taper pin holes per standard taper pin dimensions.

Installation Notes

This reamer is intended for use by qualified machinists familiar with taper reaming operations. Always apply a suitable cutting fluid to extend tool life and improve hole finish. Feed the reamer at a consistent, controlled rate and avoid excessive pressure that can cause chatter or tool deflection. Secure the workpiece firmly before beginning the operation and verify the starting hole diameter is appropriately undersized to allow proper material removal.
