Value Collection 14442960014000S Chucking Reamer Letter E

Product Description

The VALUE COLLECTION 14442960014000S is a straight-shank chucking reamer designed to finish-ream holes to a precise 0.2500 inch (Letter E) diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in light to medium production environments. The spiral flute geometry with a right-hand cut promotes smooth chip evacuation and reduces chatter during the reaming pass. With a 6 inch overall length and a 1.5 inch flute length, it fits standard drill press and lathe chuck setups used by machinists and tool-and-die technicians.

This reamer is suited for finishing through-holes and blind holes in ferrous and non-ferrous workpieces where a close-tolerance fit is required. The straight-cylindrical shank seats directly in drill chucks, collet holders, or floating reamer holders without adapters. Typical applications include bearing bores, dowel pin holes, and precision locating features in fixture and die work. It is not configured as an over- or under-size reamer and is not a dowel pin reamer.

Installation Notes

A licensed machinist or toolroom technician should set up and operate this reamer. De-energize and lock out the machine before mounting the reamer in the chuck or collet holder. Use cutting fluid appropriate for the workpiece material to extend tool life and maintain hole finish. Follow your shop's standard feeds-and-speeds procedures for HSS reamers — do not force the cut or reverse the spindle direction, as this will damage the cutting edges.
