Value Collection SM1500007 Chucking Reamer 7/64 in Cobalt

Product Description

The VALUE COLLECTION SM1500007 is a cobalt steel chucking reamer designed to finish-ream drilled holes to a precise 7/64 inch (0.1094 inch decimal) diameter. Built with four spiral flutes in a right-hand cutting direction, it removes material cleanly and leaves a smooth, accurate bore. The straight-cylindrical shank seats securely in a standard drill chuck or collet. With an overall length of 3-1/2 inches and a 7/8 inch flute length, this tool is well suited to close-tolerance finishing work in metal fabrication, maintenance, and light manufacturing environments. It ships uncoated with a bright finish.

This chucking reamer is used wherever a drilled or bored hole must be brought to a precise final diameter with a smooth surface finish. Typical applications include sizing holes for dowel pins, precision fasteners, and bearing fits in ferrous and non-ferrous metals. The cobalt steel construction provides added heat and wear resistance compared to standard high-speed steel, making it appropriate for harder workpiece materials and interrupted cuts. It is commonly used by machinists, tool-and-die workers, and maintenance mechanics in shop and field settings.

Key Features

• 7/64 inch (0.1094 inch) diameter for precise hole finishing
• Cobalt steel construction for improved heat and wear resistance over standard HSS
• 4-flute spiral design with right-hand cutting direction for clean material removal
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Bright uncoated finish — ready to use as received
• 3-1/2 inch overall length with 7/8 inch flute length for controlled reach

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with a chuck or collet sized to accept a straight-cylindrical shank in the 7/64 inch diameter range.

Installation Notes

Chucking reamers are installed by machinists and maintenance mechanics in machine tools capable of maintaining precise spindle alignment. Secure the shank fully in the chuck or collet before operation, and always allow the reamer to turn freely before engaging the workpiece. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Never reverse spindle direction while the reamer is engaged in the hole.
