Value Collection SM0406930 Chucking Reamer 0.6930 in Hss

Product Description

The VALUE COLLECTION SM0406930 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.6930-inch diameter. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers clean, accurate bore walls in ferrous and non-ferrous metals. The straight-cylindrical shank seats securely in a drill chuck or machine collet, and the right-hand cutting direction is compatible with standard spindle rotation. With a 9-inch overall length and a 2.25-inch flute length, it provides adequate reach and chip clearance for typical through-hole and blind-hole finishing operations in a machine shop or tool room environment.

This chucking reamer is suited for use in drill presses, lathes, CNC machining centers, and manual milling machines where a final-pass reaming operation is required. It is appropriate for job shop, maintenance, and production applications where hole tolerances demand a finish reamer rather than a drill alone. Licensed machinists and tool-room technicians are the primary users. The 0.6930-inch diameter falls within the 0.5000- to 0.6999-inch decimal-inch reamer range, making it a standard selection for this bore size class.

Key Features

• 0.6930-inch finished bore diameter for precise hole sizing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright, uncoated finish — no coating buildup to alter cutting geometry
• Straight-cylindrical shank fits standard drill chucks and collets without adapter
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight flute design for clean chip evacuation in through-hole applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers accepting a straight-cylindrical shank tool in this diameter range.

Installation Notes

Install the reamer in a rigid drill chuck or collet and confirm the shank is fully seated before engaging the spindle. Power down and lock out the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Reaming is a finishing operation — ensure the pre-drilled or bored hole is sized correctly to leave only the recommended stock allowance for the reamer.
