Value Collection SM0407750 Chucking Reamer 0.775 in Hss

Product Description

The VALUE COLLECTION SM0407750 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal workpieces. It produces accurate, smooth bores to a nominal diameter of 0.7750 inches, making it suitable for close-tolerance work where drilled holes require a final sizing pass. The straight flute geometry and bright uncoated finish are well suited to general-purpose reaming in ferrous and non-ferrous materials. With an overall length of 9.5 inches and a 2.5-inch flute length, this reamer provides reach into deeper setups while maintaining rigidity. It is installed by machinists and toolroom technicians using standard drill presses, lathes, or CNC machining centers with a compatible chuck.

This chucking reamer is intended for production and maintenance machining applications where consistent bore sizing is required. The straight-cylindrical shank mounts directly in a drill chuck or collet holder, making it easy to deploy on drill presses, mill-drill machines, and engine lathes. Right-hand cutting direction is standard for conventional spindle rotation. It is a general-purpose tool for machine shops, maintenance departments, and toolrooms working with holes in the 0.7750-inch nominal range.

Key Features

• 0.7750-inch nominal reaming diameter for precise bore sizing
• High-speed steel (HSS) construction provides durability across a range of workpiece materials
• Straight flute design suits general-purpose reaming in most materials
• Bright uncoated finish — ready to use out of the box or compatible with shop-applied cutting fluids
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction matches standard spindle rotation

Compatibility

Designed as a general-purpose chucking reamer for use in any machine spindle or drill chuck accepting a straight-cylindrical shank in the appropriate size range.

Installation Notes

This reamer is installed by machinists in a drill chuck, collet, or floating reamer holder — a floating holder is recommended where alignment between the spindle and the existing hole cannot be guaranteed. Power down and lock out the machine before changing tooling. Apply cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality. Do not use a chucking reamer to remove large amounts of stock; pre-drill or bore the hole to within a few thousandths of final diameter before reaming.
