Value Collection SM0406870 Chucking Reamer 0.6870 in Hss

Product Description

The VALUE COLLECTION SM0406870 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to precise tolerances. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing and smooth bore surfaces in a wide range of ferrous and non-ferrous materials. The reamer measures 0.6870 inches in diameter with a 9-inch overall length and a 2.25-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks and machine tool holders. This tool is suited for machinists, tool and die shops, and maintenance professionals working on manual or CNC lathes, drill presses, and milling machines.

This chucking reamer is intended for machine-fed reaming operations where hole diameter accuracy and finish quality are critical. It is commonly used in production and job-shop environments to bring pre-drilled holes to final size. The 0.6870-inch diameter falls within the mid-range sizing category, making it appropriate for shaft fits, dowel holes, and precision bore applications across general metalworking, manufacturing, and industrial maintenance work.

Key Features

• 0.6870-inch reamer diameter for precise hole sizing within the 0.5000 to 0.6999-inch range
• High-speed steel (HSS) construction provides hardness and wear resistance for machine reaming
• 6-flute straight design promotes smooth cutting action and consistent chip evacuation
• Bright, uncoated finish suited for general-purpose metalworking applications
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction for conventional machine-fed reaming operations

Compatibility

Designed as a general-purpose chucking reamer for use in standard machine tool setups including drill presses, lathes, and milling machines that accept a straight-cylindrical shank tooling.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with machine tool setup and cutting tool procedures. Ensure the machine spindle is fully stopped and the tool is securely clamped in the chuck or collet before beginning any setup. Use appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Never exceed the recommended feed rate for HSS reamers, as excessive feed pressure can cause tool deflection or bore oversize.
