Value Collection 144429600700000 Chucking Reamer Letter G

Product Description

The VALUE COLLECTION 144429600700000 is a high-speed steel (HSS) chucking reamer sized to Letter G, producing a finished bore diameter of 0.2610 inches. With a 6-inch overall length and a 1.5-inch straight flute section, it is designed for use in drill presses, lathes, and CNC machining centers where a precise, smooth hole finish is required. The straight-cylindrical shank seats securely in standard drill chucks or collets. The bright, uncoated HSS construction suits general-purpose reaming in ferrous and non-ferrous metals, plastics, and similar shop materials. Machinists and tool-and-die professionals rely on this style of reamer for tight-tolerance bore finishing work.

This chucking reamer is suited for production and maintenance machine shops, job shops, and toolroom environments. It is used wherever a drilled hole must be brought to a precise finished diameter — including bearing bores, pin holes, and close-tolerance fit applications. The Letter G designation corresponds to a nominal 0.2610-inch diameter, placing it in the 0.2500 to 0.2999-inch decimal inch range. Right-hand cutting direction is standard for conventional machine spindle rotation.

Key Features

• Letter G size with a finished bore diameter of 0.2610 inches
• HSS tool material for general-purpose durability across common workpiece materials
• Straight flute geometry for smooth cutting action and easy chip clearance
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright/uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank fits standard drill chucks and collets

Compatibility

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

Installation Notes

Chucking reamers are installed and operated by machinists following standard machine shop practices. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits for the required bore tolerance. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Always bring the spindle to a full stop before removing or adjusting the tool.
