Value Collection 144429603740000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429603740000 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.3740-inch diameter. The straight flute geometry and right-hand cutting direction make this reamer well suited for finishing soft to medium-hardness metals in a drill press, lathe, or CNC machining center. With an overall length of 7 inches and a 1-3/4-inch flute length, it provides adequate reach for common through-hole and blind-hole finishing operations. The bright, uncoated finish maintains dimensional integrity and is compatible with standard cutting fluids. This tool is classified as an undersize reamer at the 0.3740 U/S designation.

This chucking reamer is used in machine shop and production environments where hole tolerances require a finishing pass after drilling or rough boring. Typical applications include precision hole finishing in ferrous and non-ferrous workpieces in both job shop and light manufacturing settings. The straight-cylindrical shank seats securely in standard drill chucks and collet-style tool holders, making it straightforward to deploy on common machine tool setups. It is appropriate for skilled machinists and tool-and-die professionals working to close-tolerance specifications.

Key Features

• 0.3740-inch diameter, classified as an undersize (U/S) reamer for precision tolerance work
• High-speed steel (HSS) construction provides toughness and wear resistance across a range of workpiece materials
• Straight flute design suitable for through-holes and most standard reaming applications
• Right-hand cutting direction for use with standard forward-rotating machine spindles
• Bright, uncoated finish compatible with common cutting oils and water-soluble coolants
• Straight-cylindrical shank fits standard drill chucks and collet holders without modification

Compatibility

Designed as a machine-held chucking reamer for use in drill presses, engine lathes, turret lathes, and CNC machining centers equipped with a standard chuck or collet capable of accepting a straight-cylindrical shank in the 0.3500 to 0.3999-inch diameter range.

Installation Notes

This reamer is intended for use by qualified machinists on powered machine tools. Always secure the workpiece firmly and ensure the spindle is at an appropriate speed and feed rate for the material being reamed before engaging the tool. Apply a suitable cutting fluid to extend tool life and maintain finish quality. Never hand-turn a chucking reamer; it is designed exclusively for machine-driven operation.
