Hertel 72037021 Chucking Reamer 0.702 in Hss 8 Flute

Product Description

The HERTEL 72037021 is a straight-flute chucking reamer designed for precision hole finishing in metal machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers clean, accurate bores to a diameter of 0.7020 inches. The straight-cylindrical shank provides secure seating in standard machine chucks or collets. With 8 flutes and a 2.25-inch flute length, the tool produces consistent surface finishes in a single pass. Overall length is 9 inches, and cutting direction is right-hand. This reamer weighs 0.23 pounds and is suited for use in drill presses, lathes, and CNC machining centers.

This chucking reamer is intended for trade machinists, tool-and-die makers, and maintenance mechanics who need to bring drilled or bored holes to a precise finished diameter. It is appropriate for through-hole and blind-hole reaming operations in ferrous and non-ferrous metals where tight dimensional tolerances and smooth bore finishes are required. The 0.7020-inch diameter falls within the 0.7000 to 0.9999-inch range category, making it a standard selection for mid-range precision boring work in job shops and industrial maintenance environments.

Key Features

• 0.7020-inch finished bore diameter for precise hole sizing
• 8 straight flutes for consistent chip evacuation and surface finish
• High-speed steel (HSS) construction for durability in metal cutting
• Bright, uncoated finish suitable for general-purpose machining
• Straight-cylindrical shank compatible with standard chucks and collets
• Right-hand cutting direction, 9-inch overall length

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, milling machines, and CNC machining centers equipped with chucks or collets accepting a straight-cylindrical shank of appropriate size.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations. Ensure the workpiece and machine spindle are properly secured before use. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Never run a reamer in reverse, as this will damage the cutting edges.
