Value Collection SM1400005 Chucking Reamer 5/64 in Hss

Product Description

The VALUE COLLECTION SM1400005 is a high-speed steel (HSS) chucking reamer designed to finish-ream precision holes to a final diameter of 5/64 inch (0.0781 inch decimal). It features a straight-cylindrical shank for secure chuck mounting and a 4-flute, right-hand spiral flute geometry that promotes smooth cutting action and efficient chip evacuation. The bright, uncoated finish is suitable for general-purpose reaming in a wide range of ferrous and non-ferrous materials. Overall length is 3 inches with a 3/4 inch flute length. Machinists, toolmakers, and maintenance technicians use this reamer to bring drilled or bored holes to a close-tolerance finished size.

This chucking reamer is suited for use in drill presses, CNC machining centers, lathes, and manual milling machines where a chucked straight-shank tool is required. The small 5/64 inch diameter makes it appropriate for precision work in tight-clearance applications such as dowel pin holes, bearing bores, and close-tolerance through-holes in light-gauge steel, aluminum, brass, and similar materials. The right-hand cutting direction is standard for conventional machine spindle rotation.

Key Features

• 5/64 inch (0.0781 inch) reamer diameter for precise hole finishing
• HSS construction provides durability across a wide range of workpiece materials
• 4-flute right-hand spiral geometry for smooth, chatter-resistant cutting
• Straight-cylindrical shank for compatibility with standard drill chucks and collets
• Bright, uncoated finish suitable for general-purpose shop use
• Compact 3 inch overall length with 3/4 inch flute length for small-diameter work

Compatibility

Designed as a general-purpose chucking reamer for use in machine tools that accept a straight-cylindrical shank, including drill presses, lathes, milling machines, and CNC machining centers.

Installation Notes

Install in a suitable drill chuck or collet rated for the 5/64 inch shank diameter and confirm runout is within acceptable tolerance before reaming. Always pre-drill or bore the hole to the correct undersize before using the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Secure the workpiece firmly and operate at manufacturer-recommended speeds for small-diameter HSS reamers.
