Value Collection 144429602580000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429602580000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.2580 inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers consistent hole tolerances in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill chuck or collet, and the 6-flute geometry distributes cutting load evenly for smooth material removal and accurate sizing. It is installed and used by machinists, tool-and-die makers, and maintenance technicians performing precision hole-finishing operations on manual or CNC machine tools.

This chucking reamer is suited for general-purpose hole-finishing on the bench, mill, or drill press. The 0.2580 inch diameter places it in the 0.2500 to 0.2999 inch decimal range, making it appropriate for close-tolerance fits in fixture plates, shaft bores, and dowel-pin holes where a reamed finish is required. Right-hand cutting direction is standard for conventional clockwise spindle rotation. At 0.08 pounds, the tool is lightweight and easy to handle during setup and changeover.

Key Features

• 0.2580 inch finished-hole diameter for precise, repeatable sizing
• High-speed steel (HSS) construction provides hardness and wear resistance across a broad range of workpiece materials
• 6 straight flutes distribute cutting forces evenly and promote a smooth bore finish
• Bright, uncoated finish suitable for general-purpose machining applications
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction for standard clockwise spindle rotation

Compatibility

Designed as a general-purpose chucking reamer for use in any drill press, milling machine, or CNC machining center equipped with a chuck or collet capable of accepting a straight-cylindrical shank in the 0.2500 to 0.2999 inch diameter class.

Installation Notes

A licensed machinist or qualified operator should secure the shank fully in a drill chuck or precision collet before engaging the spindle. Always bring the spindle to a stop and isolate machine power before changing or inspecting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Do not reverse spindle direction while the reamer is engaged in the workpiece.
