Hertel 72013857 Chucking Reamer 0.1385 in Hss Straight

Product Description

The HERTEL 72013857 is a straight-flute chucking reamer designed for precision hole finishing in machined workpieces. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing performance on ferrous and non-ferrous materials. The reamer measures 0.1385 inches in diameter with a 4-inch overall length and a 1-inch flute length. Its straight-cylindrical shank seats securely in standard drill chucks and collet holders. With 4 flutes and a right-hand cutting direction, it produces smooth, accurate bores to tight tolerances. Machinists and tool room technicians use this tool for finish-reaming drilled or bored holes to final size.

This chucking reamer is suited for general-purpose machine shop applications including CNC machining centers, manual mills, and drill presses. It targets holes requiring precise diameter control in the 0.1000 to 0.1499 inch diameter range. The straight flute geometry makes it well-suited for through-hole reaming in softer materials where chip clearance is straightforward. The uncoated HSS construction allows for easy resharpening, extending tool life in production and maintenance environments.

Key Features

• 0.1385-inch reaming diameter for precise hole finishing
• High-speed steel (HSS) construction for durability and resharpenability
• 4-inch overall length with 1-inch straight flute for controlled cutting
• Straight-cylindrical shank compatible with standard chucks and collets
• Right-hand cutting direction, 4-flute configuration for smooth bore finish
• Bright, uncoated finish suitable for use with cutting fluids

Compatibility

Designed as a general-purpose chucking reamer for use in standard drill chucks, ER collet systems, and similar tool holders on machining centers, drill presses, and manual mills where a straight-cylindrical shank is accepted.

Installation Notes

Machinist or tool room personnel should secure the shank firmly in a properly sized chuck or collet before operation. Apply appropriate cutting fluid for the workpiece material to improve finish quality and extend tool life. Always bring spindle speed and feed rate within the recommended range for the reamer diameter and material being cut. Inspect the reamer for wear or damage before each use and do not exceed the designed cutting depth per pass.
