Value Collection SM0406340 Chucking Reamer 0.634 in Hss

Product Description

The VALUE COLLECTION SM0406340 is a straight-flute chucking reamer designed to bring bored or drilled holes to a precise finished diameter of 0.6340 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent cutting performance in a wide range of ferrous and non-ferrous materials. The reamer features 6 flutes with a right-hand cutting direction, a straight-cylindrical shank for secure chuck mounting, a 2.25-inch flute length, and a 9-inch overall length. Machinists and toolroom operators use this type of reamer in drill presses, lathes, and CNC machining centers where close-tolerance hole finishing is required.

This chucking reamer is suited for machine shop, production, and maintenance applications where a finished hole diameter of 0.6340 inches is needed. The straight-cylindrical shank seats directly in a standard drill chuck or collet, making it straightforward to deploy on common machine tool setups. It is appropriate for general-purpose reaming in both job shop environments and production runs where HSS tooling meets the material and speed requirements of the application.

Key Features

• Finished hole diameter of 0.6340 inches for close-tolerance sizing
• 6 straight flutes with right-hand cutting direction for smooth, consistent stock removal
• High-speed steel (HSS) construction provides durability across a broad range of workpiece materials
• Bright, uncoated finish suitable for general-purpose reaming applications
• Straight-cylindrical shank mounts directly in a drill chuck or collet without adapters
• 9-inch overall length with a 2.25-inch flute length allows reach into standard workholding setups

Compatibility

Designed as a general-purpose machine reamer compatible with drill presses, engine lathes, and machining centers equipped with a standard drill chuck or collet system sized to accept a straight-cylindrical shank.

Installation Notes

Chucking reamers should be installed by a qualified machinist following standard toolroom practices. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet to prevent runout, which is a primary cause of oversized or bell-mouthed holes. Use appropriate cutting fluid for the workpiece material and operate at the recommended surface speed for HSS tooling to maximize tool life.
