Hertel 72020951 Chucking Reamer 0.2095 in Hss 6 Flute

Product Description

The HERTEL 72020951 is a straight-flute chucking reamer designed to finish-ream pre-drilled holes to a precise 0.2095-inch diameter. Machined from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate bore finishes in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill press or lathe chucks, collets, and machine spindles. With six flutes and a 1.25-inch flute length, it produces consistent surface finish and dimensional accuracy across short to medium hole depths. Overall length is 5 inches. Licensed machinists, tool-and-die makers, and maintenance technicians install this reamer in production and jobsite environments.

This reamer is suited for machine reaming operations on drill presses, lathes, and CNC machines in both production and maintenance settings. Typical applications include finish-reaming holes in metal fixtures, bearing bores, tooling plates, and close-tolerance assemblies where hole size and finish must meet tight specifications. Its right-hand cutting direction makes it compatible with standard clockwise spindle rotation.

Key Features

• 0.2095-inch finished bore diameter within the 0.2000-0.2499 inch reamer diameter range
• 6 straight flutes for smooth, accurate material removal and consistent finish
• High-speed steel (HSS) construction for durability across a wide range of workpiece materials
• Bright, uncoated finish suitable for general-purpose machine reaming
• Straight-cylindrical shank for secure chuck, collet, or spindle mounting
• Right-hand cutting direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style machine reamer for use in standard drill press chucks, lathe tailstock chucks, and CNC tool holders accepting a straight-cylindrical shank in the corresponding shank diameter.

Installation Notes

Installation and operation should be performed by qualified machinists or maintenance technicians familiar with machine tool safety procedures. Power down and lock out the machine spindle before mounting or removing the reamer. Ensure the shank is fully seated and the chuck or collet is securely tightened before beginning the cut. Always apply appropriate cutting fluid for the workpiece material and never reverse spindle direction while the reamer is engaged in the bore.
