Value Collection SM1500025 Chucking Reamer 25/64 in

Product Description

The VALUE COLLECTION SM1500025 is a cobalt steel chucking reamer designed to finish-ream drilled or bored holes to a precise 25/64 inch (0.3906 inch decimal) diameter. The 6-flute spiral configuration with right-hand cutting direction provides smooth chip evacuation and consistent surface finish in ferrous and high-temperature alloy materials. With a 7 inch overall length and a 1-3/4 inch flute length, this reamer handles typical through-hole and blind-hole finishing operations in machine shop and field maintenance environments. The bright, uncoated finish allows visual inspection of the cutting edges before and after use. Machinists and maintenance professionals install this tool in drill presses, lathes, and machining centers.

This chucking reamer is suited for precision hole finishing in metalworking applications where tight diameter tolerances are required. The straight-cylindrical shank seats directly into standard drill chucks, collets, and floating reamer holders without adaptation. Cobalt steel construction provides greater heat resistance than standard high-speed steel, making it appropriate for stainless steel, alloy steel, and other work materials that generate elevated cutting temperatures. Typical applications include bearing seat preparation, pin hole finishing, and bushing bore sizing in production and maintenance machining.

Key Features

• 25/64 inch (0.3906 inch decimal) finished bore diameter
• Cobalt steel construction for improved heat resistance over standard HSS
• 6-flute spiral geometry with right-hand cutting direction for smooth chip flow
• Bright, uncoated finish for easy edge inspection and re-sharpening
• Straight-cylindrical shank compatible with standard drill chucks and collets
• 7 inch overall length with 1-3/4 inch flute length for versatile reach

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, machining centers, and hand-held drill motors fitted with a compatible chuck or collet sized for a straight-cylindrical shank.

Installation Notes

This tool is installed and operated by machinists or maintenance technicians familiar with reaming procedures. Ensure the workpiece is securely fixtured and the spindle is properly aligned with the pre-drilled hole before engaging the reamer. Always use an appropriate cutting fluid to extend tool life and improve surface finish. Inspect cutting edges for wear or chipping before each use and replace the tool if edge condition is compromised.
