Value Collection 144429607640000 Chucking Reamer Hss

Product Description

The VALUE COLLECTION 144429607640000 is a chucking reamer designed to finish-size drilled or bored holes to a precise 0.7640-inch diameter. Built from high-speed steel (HSS), this tool delivers the hardness and heat resistance needed for consistent performance in production and maintenance machining environments. The 10-flute straight configuration removes material evenly, reducing chatter and improving surface finish in the final pass. It mounts via a straight-cylindrical shank for direct chuck clamping on drill presses, lathes, and CNC machining centers. Machinists and tool-room technicians use this type of reamer where hole tolerances and surface finish are critical.

This chucking reamer is suited for sizing holes in a wide range of materials, including mild steels, aluminum, brass, and plastics. It falls within the 0.7000 to 0.9999-inch reamer diameter range, making it appropriate for medium-bore applications in both job-shop and production settings. The straight-cylindrical shank allows direct clamping in standard drill chucks or collet holders without an adapter. It is not an over/under-size reamer and is not configured as a dowel pin reamer, so it is intended for standard tolerance finish reaming.

Key Features

• 0.7640-inch finished-hole diameter for precise bore sizing
• HSS construction for durability and resistance to heat buildup during cutting
• 10 straight flutes for smooth, chatter-reduced material removal
• Straight-cylindrical shank for direct chuck or collet clamping
• Standard tolerance reamer — not an over/under or dowel pin configuration

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for standard machine tool setups requiring a 0.7640-inch finish-reamed bore with a straight-cylindrical shank interface.

Installation Notes

Chucking reamers are installed and operated by machinists on lathes, drill presses, or machining centers. Before mounting, ensure the spindle is fully stopped and the chuck or collet is properly cleaned and seated. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use a chucking reamer to remove excessive stock — pre-drill or bore the hole to within standard reaming allowance before the finish pass.
