Hertel 72014459 Chucking Reamer 0.1445in Hss 4 Flute

Product Description

The HERTEL 72014459 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 accurate sizing and smooth surface finishes in drilled or bored holes. The reamer measures 0.1445 inches in diameter with a 4-inch overall length and a 1-inch flute length. The straight-cylindrical shank allows secure, repeatable clamping in standard drill chucks, collets, or CNC toolholding systems. With 4 flutes and right-hand cutting direction, it is suited for general-purpose reaming in production and maintenance environments. Machinists, toolmakers, and maintenance technicians are the typical end users for this tool type.

This chucking reamer is intended for finishing holes to tight tolerances in ferrous and non-ferrous metals, plastics, and similar machinable materials. It is commonly used in manual drill press operations, CNC machining centers, and lathe tailstock setups where a straight-cylindrical shank is preferred. The 0.1445-inch diameter falls in the small-diameter range, making it appropriate for close-tolerance bore finishing in precision components such as bushings, fixtures, and mechanical assemblies.

Key Features

• 0.1445 inches diameter for small-bore precision hole finishing
• High-speed steel (HSS) construction for general-purpose machining across a range of materials
• Bright, uncoated finish — no coating buildup that could affect dimensional accuracy
• 4-flute straight design provides consistent chip flow and smooth bore finish
• Right-hand cutting direction, compatible with standard machine rotation
• Straight-cylindrical shank fits chucks, collets, and standard toolholding systems

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC machining centers, and lathe tailstocks equipped with chucks or collets that accept a straight-cylindrical shank in the small-diameter range.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists or toolmakers. Ensure the machine spindle is fully stopped and the workpiece is securely clamped before tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use this reamer as a drill — it is designed for finishing pre-drilled or bored holes only.
