Hertel 72290364 Chucking Reamer Wire 36 Hss 4 Flute

Product Description

The HERTEL 72290364 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, this reamer produces accurate, smooth bores in ferrous and non-ferrous materials. It cuts wire size 36, with a decimal diameter of 0.1065 inches, an overall length of 2.5 inches, and a flute length of 0.875 inches. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With 4 straight flutes and right-hand cutting direction, it is suited for machine reaming where consistent bore finish and dimensional accuracy are required.

This reamer is used in production and job-shop machining environments for finishing drilled or bored holes to tight tolerances. Wire size 36 diameter makes it appropriate for small-bore work commonly encountered in precision instrument components, fastener clearance holes, and tooling fixtures. It is intended for use in drill presses, lathes, milling machines, and CNC machining centers with appropriate spindle speeds and cutting fluid. Machinists and tool-and-die professionals are the primary users of this type of reamer.

Key Features

• Wire size 36 diameter (0.1065 inches) for precise small-bore finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 4 straight flutes with right-hand cutting direction for smooth, consistent material removal
• Bright, uncoated finish suitable for general-purpose machining applications
• Straight-cylindrical shank for secure chuck or collet retention
• Compact 2.5-inch overall length for use in confined setups or short-reach fixtures

Compatibility

Designed as an OEM-style chucking reamer compatible with standard drill chucks and collet systems accepting straight-cylindrical shanks in the appropriate diameter range.

Installation Notes

Installation and use should be performed by qualified machinists following applicable shop safety procedures. Secure the shank firmly in a drill chuck or collet before operation, and ensure the spindle is fully stopped before tool changes. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve bore finish. Follow manufacturer and machine tool guidelines for spindle speed and feed rate when using HSS reamers.
