Hertel 72006554 Chucking Reamer 0.0655 in Hss 4 Flute

Product Description

The HERTEL 72006554 is a high-speed steel (HSS) chucking reamer designed to finish-ream precision holes to a 0.0655-inch diameter. Built with four straight flutes and a right-hand cutting direction, it removes minimal material to bring drilled or bored holes to tight tolerances. The straight-cylindrical shank seats securely in standard drill chucks or collet holders. With an overall length of 2.5 inches and a flute length of 0.5 inches, this reamer is suited for small-diameter finish work in machine shops, tool rooms, and production environments. The bright, uncoated HSS construction works across a range of ferrous and non-ferrous workpiece materials.

This chucking reamer is used in drilling and machining operations where a precise, finished bore is required in small-diameter holes. It is appropriate for use on manual drill presses, CNC machining centers, and turret lathes. Typical applications include reaming pin holes, bushing bores, and precision locating holes in metal fabrication and toolmaking. The small 0.0655-inch diameter makes it particularly useful for intricate or fine-tolerance components where standard jobber reamers are too large.

Key Features

• 0.0655-inch finished bore diameter for tight-tolerance hole finishing
• High-speed steel (HSS) construction for durability across general machining applications
• Four straight flutes with right-hand cutting direction

• Straight-cylindrical shank for secure seating in drill chucks and collet holders
• Compact 2.5-inch overall length for use in confined setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet holders, and machine spindles accepting a straight-cylindrical shank in the 0.0500 to 0.0999-inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel. Always secure the workpiece and power down the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Do not exceed the recommended feed and speed parameters for the workpiece material and machine setup.
