Alvord Polk 03805 Taper Pin Reamer 2/0 Hss

Product Description

The ALVORD POLK 03805 is a 2/0 taper pin reamer designed for hole enlarging, hole finishing, and hole shaping in steel workpieces. Built from high-speed steel with a bright, uncoated finish, it delivers general-purpose cutting performance in machine shops and maintenance environments. The reamer runs a right-hand cut with a left-hand helical flute spiral, measuring 2.5625 inches overall with a 1.5625-inch flute length. The small end diameter is 0.1137 inches and the large end is 0.1462 inches, conforming to a 1:48 taper rate standard for 2/0 taper pin applications. Machinists and tool-and-die technicians are the primary users.

This reamer is suited for light-duty taper pin fitting operations in ferrous materials, particularly steel. It is appropriate for manual or low-speed machine reaming where precise taper pin hole preparation is required before seating a 2/0 standard taper pin. The square shank accommodates a tap wrench or matching holder for controlled hand-reaming. The three-flute helical design aids chip evacuation and promotes a cleaner finished bore in production and repair settings alike.

Compatibility

Designed as a general-purpose reamer for preparing 2/0 standard taper pin holes in steel, conforming to the 1:48 taper pin series specification.

Installation Notes

This tool is installed and used by machinists and maintenance technicians performing manual or machine reaming operations. Always secure the workpiece and de-energize any associated machinery before reaming. Use appropriate cutting fluid when reaming steel to extend tool life and improve bore finish. Do not force the reamer through the hole; apply steady, even pressure to avoid deflection or chatter.
