Alvord Polk 09602 Taper Pin Reamer 3mm Hss 4 Flute

Product Description

The ALVORD POLK 09602 is a straight-flute taper pin reamer designed for enlarging, finishing, and shaping tapered pin holes in steel workpieces. Built from high speed steel (HSS) with a bright, uncoated finish, this reamer delivers general-purpose performance for precision hole work. It carries a 3 mm taper pin size with a small end diameter of 0.1142 inches and a large end diameter of 0.1600 inches, following a 1:50 taper rate. The square shank allows positive drive in a standard reamer wrench or brace. Four straight flutes provide clean, controlled material removal through the 2.48-inch flute length.

This reamer is suited for machine shops, toolrooms, and maintenance environments where taper pin fits must be accurately sized or refitted. It is used by machinists and tool-and-die professionals working on shafts, hubs, and assemblies that rely on taper pins for positive locking. Typical applications include hole enlarging and hole finishing in steel components where a precise tapered seat is required. The overall length of 3.468 inches makes it manageable in both hand and machine setups.

Compatibility

Designed as an OEM-style replacement or standard toolroom reamer for applications requiring a No. 3 mm taper pin hole in steel components.

Installation Notes

This reamer is typically used by machinists and maintenance technicians working on taper pin assemblies. Secure the workpiece firmly before reaming, and apply cutting fluid appropriate for steel to extend tool life and improve finish quality. Use steady, even feed pressure and avoid reversing the reamer under load, as this can damage the cutting edges. Always deburr the reamed hole before driving the taper pin to final position.
