Value Collection ST0110016 Chucking Reamer Letter E Hss

Product Description

The VALUE COLLECTION ST0110016 is a straight-flute chucking reamer designed to finish-ream holes to a precise Letter E diameter of 0.2500 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance in a wide range of ferrous and non-ferrous materials. The reamer mounts via a 1MT Morse Taper shank, seating securely in compatible drill press or lathe spindles. With 6 right-hand flutes and a right-hand cutting direction, it produces smooth, accurate bores with minimal chatter. Machinists and toolroom professionals install this reamer when hole tolerance and surface finish are critical to assembly fit.

This chucking reamer is suited for toolroom, machine shop, and production environments where drilled holes require final sizing to a Letter E (0.2500 inch) diameter. The 1MT Morse Taper shank makes it a direct fit for benchtop drill presses, lathes, and milling machines equipped with a No. 1 Morse Taper spindle or sleeve. It handles light material removal to bring pre-drilled or bored holes to final dimension, and is appropriate for both short-run repair work and repetitive production reaming operations.

Key Features

• Letter E diameter — 0.2500 inches finished hole size
• HSS construction for cutting hardened and abrasion-resistant materials at moderate speeds
• 6 straight flutes with right-hand cutting direction for smooth, controlled material removal
• 1MT Morse Taper shank for positive seating and easy removal with a drift key
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• 6 inch overall length with 1.5 inch flute length for reach in standard workpiece depths

Compatibility

Designed for use in drill presses, lathes, and milling machines fitted with a No. 1 Morse Taper (1MT) spindle or adapter sleeve.

Installation Notes

A licensed machinist or skilled toolroom technician should install and operate this reamer. Always power down and lock out the machine spindle before seating or removing the Morse Taper shank. Use a proper drift key in the spindle slot to eject the taper — never strike the reamer body directly. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish.
