Value Collection SM0407690 Chucking Reamer Hss 0.7690 in

Product Description

The VALUE COLLECTION SM0407690 is a straight-flute chucking reamer machined from high-speed steel (HSS) for precise hole finishing in metal workpieces. It carries a 0.7690-inch cutting diameter and an overall length of 9.5 inches, with a 2.5-inch flute length that provides controlled chip clearance during through-hole and blind-hole reaming operations. The bright, uncoated finish suits general-purpose ferrous and non-ferrous applications. The straight-cylindrical shank seats securely in drill press chucks, CNC turning centers, or manual lathes. Machinists and tool-and-die professionals use this reamer to bring drilled or bored holes to tight dimensional tolerances.

This chucking reamer is suited to production and maintenance machining environments where hole-diameter accuracy and finish quality are required. It performs in light-to-medium stock-removal passes on steel, cast iron, aluminum, and similar materials. The right-hand cutting direction is standard for conventional spindle rotation. Its straight flute geometry makes it a practical choice for through-hole applications where chip evacuation along the flute length is sufficient. Shops requiring precise fit for pins, bushings, or bearing seats will find this reamer appropriate for that class of work.

Key Features

• 0.7690-inch cutting diameter for accurate hole sizing in the 0.7000 to 0.9999-inch range class
• HSS tool material provides hardness and toughness for general-purpose machining
• Straight flute geometry promotes smooth chip flow in through-hole operations
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• Right-hand cutting direction matches conventional spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC machining centers, lathes, and manual drilling equipment fitted with chucks or collet systems that accept a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by machinists following standard shop safety practices. Secure the shank fully in the chuck or collet and verify runout before beginning the cut. Always reduce spindle speed relative to drilling and apply cutting fluid appropriate for the workpiece material to extend tool life and improve finish quality. Never use a reamer to remove excessive stock — rough-drill or bore the hole to within a few thousandths of final diameter before reaming.
