Value Collection SM0406790 Chucking Reamer 0.6790 in Hss

Product Description

The Value Collection SM0406790 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise 0.6790-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance across a wide range of ferrous and non-ferrous workpiece materials. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With a 9-inch overall length (OAL) and a 2.25-inch flute length, this reamer suits general-purpose production and maintenance machining operations. Six right-hand flutes distribute cutting load evenly and promote clean hole finish with minimal chatter.

This chucking reamer is intended for manual and CNC machine tool applications where hole diameter accuracy and surface finish are critical. Typical use cases include finish-reaming through-holes and blind holes in machine parts, fixtures, and assemblies on lathes, drill presses, and machining centers. It is sized within the 0.5000-to-0.6999-inch decimal-inch reamer diameter range and is suited for job shop, toolroom, and light production environments where a general-purpose HSS reamer is specified. Installation is performed by machinists and toolroom technicians working to standard engineering tolerances.

Key Features

• 0.6790-inch reamer diameter for precise finished-hole sizing
• High-speed steel (HSS) construction for durability across common workpiece materials
• Six straight flutes with right-hand cutting direction for smooth, consistent stock removal
• Bright, uncoated finish — ready to run without additional surface treatment
• Straight-cylindrical shank for direct chucking in standard drill chucks or collets
• 9-inch OAL with 2.25-inch flute length suits a range of hole depth requirements

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks, collet holders, and floating reamer holders on lathes, drill presses, and machining centers accepting straight-cylindrical shank tooling.

Installation Notes

Chucking reamers are installed and operated by machinists and toolroom professionals. Ensure the workpiece is securely fixtured and the spindle is powered down before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole finish. Never use a reamer to remove excessive material — pre-drill or bore the hole to within accepted stock-allowance guidelines before reaming.
