Value Collection SM0407420 Chucking Reamer 0.7420 in Hss

Product Description

The VALUE COLLECTION SM0407420 is a straight-flute chucking reamer designed for precision hole finishing in metal workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing of drilled or bored holes to a finished diameter of 0.7420 inches. The straight-cylindrical shank seats securely in standard drill chucks or collet holders, making it a reliable choice for use in drill presses, lathes, and machining centers. With 6 flutes and right-hand cutting direction, it produces smooth, consistent bore surfaces. Machinists and tool-and-die tradespeople routinely specify this type of reamer for production and maintenance applications.

This reamer is suited for finishing through-holes and blind holes in ferrous and non-ferrous metals where tight dimensional tolerances are required. It is commonly used in job shops, maintenance facilities, and manufacturing environments. At 9-1/2 inches overall length and a 2-1/2 inch flute length, it handles standard-depth holes in typical workpiece thicknesses without excessive tool overhang.

Key Features

• Finished reamer diameter of 0.7420 inches for precise hole sizing
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• 6 straight flutes with right-hand cutting direction for smooth bore finish
• Bright, uncoated finish suitable for use with cutting fluids
• Straight-cylindrical shank for compatibility with standard drill chucks and collet systems
• 9-1/2 inch overall length with 2-1/2 inch flute length for standard-depth applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with drill chucks or collet holders accepting a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed by machinists using standard chuck or collet toolholding setups. Ensure the machine spindle is fully stopped and the chuck is securely tightened before beginning the operation. Always apply a suitable cutting fluid to extend tool life and improve surface finish. Reaming is performed after drilling to final size, typically removing only a small amount of material to achieve the target bore diameter.
