Value Collection 24004380 Chucking Reamer 0.438 in Carbide

Product Description

The VALUE COLLECTION 24004380 is a carbide-tipped chucking reamer designed to finish-ream holes to tight tolerances in a machine tool setup. With a 0.438 inch diameter and a diameter tolerance of +0.0003 to -0.0000 inches, this reamer holds size accurately for precision bore finishing in metal fabrication and machining applications. The 4-flute straight configuration and bright uncoated finish make it well suited for use in drill presses, lathes, and CNC machining centers. At 7 inches overall length with a 1.75 inch flute length, it offers adequate reach for most standard workpiece thicknesses. Machinists and tool-and-die technicians are the primary users of this type of reamer.

This chucking reamer is used in machine-based holemaking operations where a drilled or bored hole must be brought to a final diameter with consistent roundness and surface finish. The straight cylindrical shank allows direct mounting in standard drill chucks or collet holders. It is appropriate for right-hand cutting operations in ferrous and non-ferrous materials. Typical applications include production runs requiring repeatable hole sizing, fixture fabrication, and component finishing work in job shops and manufacturing environments.

Key Features

• Carbide-tipped cutting edges for extended tool life in abrasive or harder materials
• Diameter tolerance of +0.0003 to -0.0000 inches for precise final hole sizing
• 4-flute straight configuration promotes smooth chip evacuation and consistent finish
• Straight cylindrical shank for direct mounting in standard chucks or collet holders
• Bright uncoated finish - no coating buildup to affect dimensional accuracy
• Right-hand cutting direction compatible with standard machine spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, and machining centers that accept straight-shank tooling in the applicable diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or toolroom technician. Before mounting, ensure the machine spindle is fully stopped and the chuck or collet is clean and free of debris to prevent runout. Secure the straight shank firmly in the chuck or collet holder before beginning the reaming pass, and use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Never use a hand reamer in a power machine, and do not attempt to remove excessive stock in a single reaming pass.
