Value Collection SM0406910 Chucking Reamer Hss 6 Flute

Product Description

The VALUE COLLECTION SM0406910 is a straight-flute chucking reamer designed to bring bored or drilled holes to a precise final diameter. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing at 0.6910 inches diameter with a 9-inch overall length and a 2.25-inch flute length. The six straight flutes cut in a right-hand direction, producing clean, consistent hole walls in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in drill press or lathe chucks, keeping the tool concentric during the finishing pass. Machinists and tool-room technicians reach for this style of reamer when tolerances require more precision than a drill alone can hold.

This chucking reamer is suited for machine-reaming operations on drill presses, lathes, and milling machines in production shops, job shops, and maintenance environments. It is sized within the 0.5000 to 0.6999 decimal-inch reamer diameter range, making it appropriate for finishing holes in steel, cast iron, aluminum, and similar materials where a smooth bore and tight dimensional tolerance are required. It is sold individually and is intended for single-spindle, machine-driven use rather than hand reaming.

Key Features

• 0.6910-inch finished hole diameter for precise bore sizing
• HSS construction provides durability across a wide range of common workpiece materials
• Six straight flutes with right-hand cutting direction for smooth, consistent material removal
• Bright, uncoated finish — ready to use as supplied or receptive to aftermarket coatings
• Straight-cylindrical shank for secure, concentric chuck or collet holding
• 9-inch overall length provides reach for deeper setups without excessive overhang

Compatibility

Designed as a machine chucking reamer for use in drill presses, engine lathes, and milling machines equipped with a standard chuck or collet system that accepts a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and removed by a qualified machinist with the spindle fully stopped and the machine power locked out. The shank should be gripped firmly in a drill chuck or collet, with minimal runout verified before cutting. Reaming is typically performed at reduced spindle speed compared to drilling, with appropriate cutting fluid applied for the workpiece material. Never use a chucking reamer as a hand reamer — it is designed for machine-driven rotation only.
