Value Collection 5-013-085 Hand Expansion Reamer

Product Description

The VALUE COLLECTION 5-013-085 is a hand expansion reamer designed for precision bore finishing and slight diameter adjustments in metal workpieces. Built from high-speed steel with a bright, uncoated finish, this tool delivers reliable cutting performance in manual reaming applications. The straight flute geometry and right-hand cut make it suitable for through-hole and blind-hole reaming in ferrous and non-ferrous materials. With a nominal diameter of 0.75 inches and a maximum expansion of 0.006 inches, it gives machinists and toolmakers a controlled range of final bore sizing without requiring a dedicated fixed reamer for each diameter increment.

This reamer is used in machine shops, maintenance facilities, and fabrication environments where hand reaming is performed to achieve close-tolerance bore fits. It is appropriate for use on lathes, drill presses, or by hand with a tap wrench when final bore correction or light stock removal is needed. The 3.5-inch flute length and 8-inch overall length accommodate moderate workpiece depths while maintaining good chip clearance. Machinists, toolmakers, and maintenance technicians working on mechanical assemblies are the primary users of this tool.

Key Features

• 0.75 inch nominal reamer diameter with up to 0.006 inch maximum expansion range
• 8 straight flutes for smooth, consistent cutting action and efficient chip evacuation
• High-speed steel construction provides durability across a range of workpiece materials
• Right-hand cut for standard reaming applications
• Cylindrical straight shank compatible with standard drill chucks and tap wrenches
• Bright, uncoated finish suitable for general-purpose use without added coating concerns

Compatibility

Designed as a general-purpose hand expansion reamer for use in standard reaming operations requiring a 0.75 inch nominal bore diameter within the 0.7000 to 0.9999 inch reamer diameter range.

Installation Notes

Hand expansion reamers should be installed and adjusted by qualified machinists or toolmakers familiar with bore finishing procedures. Always secure the workpiece fully before reaming and ensure the reamer is aligned true to the bore axis to avoid bell-mouthing or taper. Expansion adjustments should be made in small increments; never exceed the stated maximum expansion of 0.006 inches. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
