Value Collection 144429603910000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603910000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3910-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate bores in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill press chuck, turret lathe, or CNC toolholder. With 6 flutes and a right-hand cutting direction, this reamer provides smooth material removal and consistent hole geometry in production and maintenance machining environments. Machinists, tool-and-die technicians, and maintenance mechanics are the primary users.

This chucking reamer is suited for finishing holes in machine components, fixtures, jigs, and assemblies where tight dimensional tolerances and smooth surface finish are required. It is appropriate for use in drill presses, lathes, milling machines, and CNC machining centers across job shop, production floor, and maintenance repair operations (MRO) settings. The 0.3910-inch diameter falls within the 0.3500- to 0.3999-inch decimal inch reamer range.

Key Features

• 0.3910-inch reamer diameter for precise hole finishing
• HSS construction provides toughness and wear resistance across common workpiece materials
• 6 straight flutes for smooth cutting action and consistent hole geometry
• Right-hand cutting direction compatible with standard machine rotation
• Straight-cylindrical shank for secure chuck or collet retention
• Bright uncoated finish suitable for use with cutting fluids

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped with a drill chuck, collet, or toolholder accepting a straight-cylindrical shank at the 0.3910-inch diameter size.

Installation Notes

Chucking reamers are installed by qualified machinists following standard machine shop practices. Ensure the machine spindle is fully stopped and the tool is secured with adequate shank engagement before operation. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Always ream to final size from a pre-drilled or bored undersize hole — do not attempt to remove excessive stock with a reamer.
