Value Collection 14442960256400S Chucking Reamer Hss

Product Description

The VALUE COLLECTION 14442960256400S is a straight-flute chucking reamer designed to finish-ream pre-drilled holes to a precise 25/64 inch (0.3906 inch decimal) diameter. Built from high-speed steel (HSS), it delivers consistent cutting performance on a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill press chuck or machine spindle, making setup straightforward. With an overall length of 7 inches and a flute length of 1-3/4 inches, this reamer is sized for general-purpose finishing work where tight hole tolerances are required. The right-hand spiral flute geometry promotes smooth chip evacuation and reduces chatter during the cut.

This chucking reamer is suited for machine shop, maintenance, and production environments where drilled holes need to be brought to a finished diameter with close tolerance and smooth surface finish. Typical applications include reaming bearing bores, bushing seats, and locating-pin holes in metal fabrication and general machining operations. It is used in drill presses, lathes, and milling machines by machinists and maintenance technicians working in industrial and manufacturing settings.

Key Features

• HSS construction provides wear resistance and cutting durability across common metals
• Right-hand spiral flute geometry promotes efficient chip evacuation and smooth hole finish
• Straight-cylindrical shank for direct mounting in standard drill chucks or collets
• 25/64 inch (0.3906 inch) finished diameter for precise hole sizing
• 7 inch overall length with 1-3/4 inch flute length for general-purpose reach
• Right-hand cutting direction compatible with standard machine rotation

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and milling machines equipped with standard drill chucks or collet systems accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by machinists or maintenance technicians in a machine spindle using a drill chuck or collet. Always ensure the workpiece and machine are properly secured before operation, and confirm spindle speed is set appropriately for the material being reamed — reaming typically requires lower RPM and higher feed rates than drilling. Apply cutting fluid to extend tool life and improve surface finish. Never attempt to rotate a reamer by hand in a finished bore, as this can dull the cutting edges.
