Value Collection 144429603080000 Chucking Reamer 0.308 in Hss

Product Description

The VALUE COLLECTION 144429603080000 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3080-inch diameter. Constructed from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate hole geometry in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With 6 flutes and a right-hand cutting direction, this reamer provides smooth chip evacuation and consistent surface finish in production and maintenance machining operations.

This reamer is suited for machine shop, tool room, and general manufacturing environments where tight bore tolerances are required. It is commonly used in CNC machining centers, drill presses, and manual lathes. Typical applications include finishing bearing bores, pin holes, and dowel holes where a precise, smooth internal diameter is critical. Machinists and tool room technicians install this reamer as part of a two-step drill-and-ream process to achieve final hole size.

Key Features

• 0.3080-inch finished hole diameter for precise bore sizing
• 6-flute straight-flute geometry for smooth chip flow and consistent finish
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright, uncoated finish suitable for use with cutting fluids
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for machine tool setups requiring a 0.3080-inch finish diameter with a straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Before mounting, verify that the machine spindle and chuck or collet are clean and in good condition to ensure true runout. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Pre-drill or bore the hole to the correct undersize before reaming — never attempt to remove excessive stock with a reamer.
