Value Collection SM0406920 Chucking Reamer 0.6920 in Hss

Product Description

The VALUE COLLECTION SM0406920 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.6920-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent dimensional accuracy in a wide range of ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in a drill chuck or collet, and the right-hand cutting geometry with 6 flutes produces clean, true hole finishes. Overall length is 9 inches with a 2.25-inch flute length, keeping the tool rigid during through-hole and blind-hole reaming operations. Machinists, tool-and-die technicians, and maintenance professionals are the primary users of this tool.

This reamer is suited for machine-shop production work, maintenance and repair operations, and toolroom applications where close-tolerance hole finishing is required. It is intended for use in drill presses, lathes, milling machines, and CNC machining centers equipped with a straight-shank chuck or collet. The 0.6920-inch diameter falls within the 0.5000- to 0.6999-inch reamer diameter range, making it appropriate for medium-bore finishing tasks in both job-shop and production environments.

Key Features

• 0.6920-inch finished-hole diameter for precise, close-tolerance reaming
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• 6 straight flutes with right-hand cutting direction for smooth, consistent chip evacuation
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank compatible with standard drill chucks and collets
• 9-inch overall length with 2.25-inch flute length for rigidity in through-hole and blind-hole applications

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for machine tools accepting a straight-cylindrical shank in the 0.6920-inch diameter class, including drill presses, lathes, milling machines, and CNC machining centers with compatible chuck or collet systems.

Installation Notes

Chucking reamers should be installed by qualified machinists following standard shop practices. Ensure the machine spindle is fully stopped and the chuck or collet is clean and free of debris before inserting the shank. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not attempt to remove significant stock with a reamer — pre-drill or bore holes to within a few thousandths of final diameter before reaming.
