Value Collection 556u 6 Taper Pin Reamer No 6 Pin Hss

Product Description

The VALUE COLLECTION 556u 6 is a straight-flute taper pin reamer designed to finish and size tapered holes for No. 6 taper pins. Machined from high-speed steel with a bright, uncoated finish, it delivers clean material removal in both hole enlarging and hole finishing operations. The small end diameter is 0.2773 inches and the large end diameter is 0.3540 inches, with a taper rate of 1:48. The right-hand cut geometry and square shank make it compatible with standard machine setups and hand-reaming operations. This tool is suited for general-purpose work in production and maintenance environments where precise tapered hole fitment is required.

This reamer is used wherever No. 6 taper pins are driven to lock hubs, collars, or mechanical components onto shafts. It is commonly used in machine shops, maintenance facilities, and assembly operations handling general metalworking tasks. The tool handles hole enlarging, hole finishing, and hole shaping applications across a range of ferrous and non-ferrous materials. It is appropriate for use in manual or machine reaming setups where a No. 6 taper pin fit is specified on the job drawing.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians using a standard T-handle, tap wrench, or machine spindle with a square-drive adapter. Secure the workpiece firmly before reaming and apply cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality. Advance the reamer steadily without forcing to avoid chatter or oversizing the hole. Verify final hole diameter and taper fit against the mating taper pin before assembly.
