Value Collection 144429602850000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602850000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.2850-inch diameter. The straight-flute geometry and bright uncoated finish make this reamer well-suited for general-purpose hole finishing in a wide range of ferrous and non-ferrous materials. With six flutes and a right-hand cutting direction, it delivers smooth, accurate bore surfaces in production and maintenance environments. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. Machinists, tool-and-die makers, and maintenance technicians use this type of reamer to bring undersized or rough-bored holes to final tolerance.

This chucking reamer is intended for use in drill presses, lathes, and machining centers where a machine-driven reaming operation is required. It is appropriate for through-hole and blind-hole applications in general shop work, job shops, and industrial maintenance settings. The 0.2850-inch diameter falls within the 0.2500 to 0.2999-inch range, making it a standard sizing option for precision hole finishing tasks that require consistent diameter control across multiple workpieces.

Key Features

• 0.2850-inch finished-hole diameter for precision bore sizing
• High-speed steel (HSS) construction provides durability across a range of materials
• Six straight flutes for smooth cutting action and clean hole finish
• Right-hand cutting direction compatible with standard machine rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Bright uncoated finish — no additional coating to affect tolerance or chip clearance

Compatibility

Designed as a general-purpose machine chucking reamer suitable for use in drill presses, lathes, turret machines, and CNC machining centers equipped with a standard chuck or collet capable of accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by licensed machinists or qualified maintenance technicians using a drill chuck or collet holder sized to the shank diameter. Always ensure the workpiece is securely fixtured and the spindle speed is set to the appropriate RPM for the material and reamer diameter before beginning the cut. Use cutting fluid appropriate to the workpiece material to extend tool life and improve surface finish. Never use a chucking reamer as a hand reamer — it is designed for machine-driven rotation only.
