Hertel 8272544 Chucking Reamer 0.635 in Hss 8 Flute

Product Description

The HERTEL 8272544 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing and smooth surface finishes in drilled or bored holes. The reamer measures 0.6350 inches in diameter with a 9-inch overall length and a 2.25-inch flute length. An 8-flute configuration provides stability and finish quality at standard cutting speeds. The straight-cylindrical shank mounts directly in drill chucks or collet holders. Machinists and tool-and-die professionals install this reamer in drill presses, lathes, and machining centers where controlled material removal is required to bring holes to final tolerance.

This chucking reamer is suited for production and maintenance machining environments where holes must be reamed to a precise 0.6350-inch finished diameter. Typical applications include fixture work, jig boring, and component assembly preparation in job shops, manufacturing facilities, and maintenance repair operations. Right-hand cutting direction makes it compatible with standard spindle rotation on conventional machine tools. It is sold individually and is appropriate wherever a 0.635-inch nominal hole size is required in steel, cast iron, aluminum, or similar machinable materials.

Key Features

• 0.6350-inch reamer diameter for precise hole finishing to nominal size
• 8 straight flutes for smooth finish and consistent chip clearance
• High-speed steel (HSS) construction for durability across a range of machinable metals
• Bright, uncoated finish suitable for use with standard cutting fluids
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction compatible with standard machine tool spindles

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with drill chucks or collet systems accepting a straight-cylindrical shank of 0.6350 inches.

Installation Notes

Chucking reamers are installed by qualified machinists following standard machining safety procedures. Power down and lock out the machine spindle before mounting or removing the tool. Secure the straight-cylindrical shank firmly in a drill chuck or collet holder to prevent runout. Always use an appropriate cutting fluid for the workpiece material, and never attempt to rotate a chucking reamer by hand to remove it from a tight hole.
