Value Collection SM0405080 Chucking Reamer 0.5080 in Hss

Product Description

The VALUE COLLECTION SM0405080 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise diameter of 0.5080 inches with a tolerance of +0.0001 to +0.0003 inches. Constructed from high-speed steel (HSS) with a bright, uncoated finish, it is built for use in manual or CNC machine tool setups where a close-tolerance fit is required. The 6-flute, right-hand cutting geometry provides a smooth, controlled cut. With an overall length of 8 inches and a 2-inch flute length, this reamer suits moderate-depth finishing operations in machine shops and production environments.

This chucking reamer is suited for finishing holes in ferrous and non-ferrous workpiece materials where dimensional accuracy and surface finish are critical. The straight-cylindrical shank seats directly into a drill chuck or collet, making setup straightforward on drill presses, lathes, and machining centers. It is a practical choice for general-purpose reaming work in job shop and maintenance machining applications where an HSS, uncoated tool is appropriate for the material and cutting speed being used.

Key Features

• Reamer diameter of 0.5080 inches with a tight tolerance of +0.0001 to +0.0003 inches for precision hole finishing
• 6-flute, straight-flute geometry with right-hand cutting direction for smooth material removal
• HSS construction with bright, uncoated finish suitable for general-purpose machining
• Straight-cylindrical shank compatible with standard drill chucks and collets
• 8-inch overall length with a 2-inch flute length for moderate-depth reaming operations
• Series 272 design — no coolant-through feature, sized within the 0.5000 to 0.6999 inch diameter range

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a standard drill chuck or collet that accepts a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by qualified machinists following standard machine tool practices. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify runout is within acceptable limits. Always reduce spindle speed relative to drilling operations and apply appropriate cutting fluid for the workpiece material to achieve the best bore finish and tool life. Never use a chucking reamer to remove excessive stock — pre-drill or bore the hole to within the recommended allowance before reaming.
