Hertel 72291230 Chucking Reamer 23/64 in Hss 6 Flute

Product Description

The HERTEL 72291230 is a straight-flute chucking reamer designed to finish-ream drilled or bored holes to a precise diameter of 0.3594 inches (23/64 inch). Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers clean, accurate sizing in a wide range of ferrous and non-ferrous materials. The 6-flute, right-hand cutting geometry produces a smooth surface finish while maintaining dimensional control. With an overall length of 4-7/8 inches and a 1-3/4 inch flute length, this reamer fits standard drill press chucks and CNC or manual lathe toolholders. It weighs 0.15 pounds and ships individually.

This reamer is suited for machine shop, toolroom, and production floor applications where hole tolerance and finish are critical. The straight-cylindrical shank seats securely in standard chucks without requiring a Morse taper adapter. Right-hand cutting direction is compatible with conventional spindle rotation. Typical applications include finish-reaming through-holes and blind holes in workholding fixtures, dies, jigs, and general machined components. It is not configured as a dowel pin or over/under size reamer.

Key Features

• Reamer diameter: 23/64 inch (0.3594 inches decimal) for precise hole finishing

• High-speed steel (HSS) construction for durability across a broad range of workpiece materials
• Bright/uncoated finish — ready to use as delivered, no coating to chip or flake
• Straight-cylindrical shank fits standard drill chucks and collet holders
• Right-hand cutting direction matches conventional machine spindle rotation

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with a chuck or collet capable of holding a straight-cylindrical shank.

Installation Notes

Chucking reamers are installed and operated by qualified machinists following standard machine tool safety procedures. Power down and lock out the machine spindle before installing or removing the reamer. Secure the straight-cylindrical shank firmly in the chuck or collet to prevent runout. Always use appropriate cutting fluid for the workpiece material, and feed at a controlled rate to avoid overloading the flutes or damaging the finished bore.
