This is a new Yankee No. 433 straight-flute taper reamer in 57/64 in (0.8906 in) size, manufactured in the USA from High Speed Steel (HSS). The No. 433 series is a standard taper pin reamer designed to produce tapered holes conforming to the American Standard taper pin taper of 1/4 in per foot, used for fitting standard taper pins in shafts, hubs, and mechanical assemblies requiring precise, removable locating or locking connections. Straight flutes provide clean cutting action suited to through-hole or interrupted reaming operations in steel, cast iron, aluminum, and similar machinable materials. The reamer is driven via its straight cylindrical shank and is compatible with standard drill chucks, collet chucks, and straight-shank toolholders. New-old-stock condition with original Yankee label intact.
