Cleveland C25072 Chucking Reamer Wire 51 Hss Straight Flute

Product Description

The CLEVELAND C25072 is a straight-flute chucking reamer designed for precision hole finishing in machine shop and metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it produces accurate, smooth bores in ferrous and non-ferrous materials. The reamer is sized to wire gauge No. 51, with a decimal diameter of 0.0670 inches and a 3-inch overall length. Four right-hand-cut flutes provide stable cutting action and clean chip evacuation through the 0.75-inch flute length. A straight shank allows secure clamping in a standard drill chuck or collet holder on a lathe, drill press, or milling machine.

This chucking reamer is suited for precision reaming operations in production and job-shop environments. It is used to bring drilled or bored holes to a tight-tolerance finished diameter in the 0.0500 to 0.0999 inch decimal range. Typical applications include fixture work, toolmaking, and light mechanical assembly where hole location and diameter accuracy are critical. It is installed and operated by machinists and toolmakers working with manually controlled or CNC machine tools.

Key Features

• Wire size No. 51 with 0.0670 inch decimal diameter for tight-tolerance hole finishing
• High-speed steel construction for durability across a range of workpiece materials
• Four right-hand-cut straight flutes for smooth cutting action and chip clearance
• Bright, uncoated finish suitable for use with cutting fluids
• Straight shank for use in standard drill chucks or collet holders

Compatibility

Designed for use as a chucking reamer on lathes, drill presses, and milling machines equipped with standard straight-shank toolholders or collet systems accepting the appropriate shank diameter.

Installation Notes

Installation and operation should be performed by a qualified machinist. Power down the machine and release all energy before mounting or removing the reamer. Ensure the straight shank is properly seated and secured in the chuck or collet before starting the spindle. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish quality.
