Value Collection SM0407000 Chucking Reamer 0.7000 in Hss

Product Description

The VALUE COLLECTION SM0407000 is a straight-flute chucking reamer designed for precision hole finishing in machine shop and production environments. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing performance in ferrous and non-ferrous materials. The 0.7000 inch diameter is held to a tight tolerance of +0.0003 to -0.0000 inches, ensuring accurate final bore dimensions. At 9 inches overall length with a 2.25 inch flute length, this reamer is suited for through-hole and moderate-depth blind-hole applications. The straight-cylindrical shank mounts directly in drill chucks or collet holders.

This chucking reamer is used in manual mills, drill presses, CNC machining centers, and lathe tailstock setups wherever a reamed fit is required. Typical applications include production reaming of bearing bores, pin holes, and close-tolerance locating holes in ferrous metals, aluminum, brass, and plastics. The 6-flute geometry provides smooth surface finish and even chip load distribution across the cutting edges. Right-hand cutting direction is standard for conventional spindle rotation.

Key Features

• 0.7000 inch diameter with +0.0003 to -0.0000 inch tolerance for close-fit bore finishing
• 6-flute straight geometry for smooth surface finish and reduced chatter
• High-speed steel (HSS) construction for wear resistance across a wide range of materials
• Bright, uncoated finish — compatible with most cutting fluids and coolants
• Straight-cylindrical shank for direct mounting in standard drill chucks or collet holders
• Right-hand cutting direction for use with standard clockwise spindle rotation

Compatibility

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

Installation Notes

Chucking reamers are installed by machinists and toolroom professionals. Secure the straight shank firmly in a drill chuck or precision collet before use, and verify runout with an indicator before cutting. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use a chucking reamer to remove more material than the pre-drill allowance justifies — pre-drill to the appropriate undersize before reaming.
