Hertel 72010705 Chucking Reamer 0.1070 in Hss 4 Flute

Product Description

The HERTEL 72010705 is a straight-flute chucking reamer designed for precision hole finishing in machining operations. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing and smooth surface finishes in a wide range of ferrous and non-ferrous materials. The reamer measures 0.1070 inches in diameter with an overall length of 3.5 inches and a 7/8-inch flute length. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. Machinists and tool-and-die professionals rely on this style of reamer for production drilling where tight bore tolerances are required.

This chucking reamer is suited for use in vertical mills, drill presses, lathes, and CNC machining centers handling light to medium-duty reaming operations. Its 0.1070-inch diameter places it in the small-bore range, making it a practical choice for precision holes in fixtures, jigs, dies, and small mechanical components. The right-hand cutting direction is compatible with conventional machine spindle rotation. Sold individually, it fits shops that need a single replacement or low-volume tooling replenishment.

Key Features

• 0.1070-inch diameter provides accurate small-bore sizing for tight-tolerance applications
• High-speed steel (HSS) construction offers durability across a range of workpiece materials
• Bright, uncoated finish allows for easy visual inspection of cutting edges
• 4-flute straight configuration delivers smooth, consistent material removal
• Straight-cylindrical shank is compatible with 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 any machine tool accepting a straight-cylindrical shank in the corresponding diameter range, including drill presses, milling machines, lathes, and CNC machining centers.

Installation Notes

Install in a properly sized drill chuck or collet holder and ensure the shank is fully seated and securely clamped before operation. Always bring the machine spindle to a complete stop before changing or adjusting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality. Inspect cutting edges for wear or chipping before each use, and replace when edge condition degrades to avoid out-of-tolerance bores.
