Hertel 72006158 Chucking Reamer 0.0615 in Hss Straight

Product Description

The HERTEL 72006158 is a straight-flute chucking reamer designed for precision hole finishing in machine tool applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent sizing and surface finish in through-hole and blind-hole reaming operations. The reamer measures 0.0615 inches in diameter with a 2.5 inch overall length and a 0.5 inch flute length. The straight-cylindrical shank seats securely in drill chucks and collet holders. Four right-hand flutes provide smooth cutting action suited to a range of ferrous and non-ferrous workpiece materials. This tool is sold individually and intended for use by machinists and toolroom professionals.

This chucking reamer is used in machine shop and toolroom environments where precise hole sizing to 0.0615 inches is required. Typical applications include finishing drilled holes in jigs, fixtures, and precision components where tight tolerances and smooth bore finish are critical. The small-diameter geometry makes it appropriate for work on instrument parts, small fastener holes, and similar detail machining tasks. It is intended for use in drill presses, CNC machining centers, lathes, and manual milling machines equipped with appropriate chuck or collet toolholding.

Key Features

• 0.0615 inch reamer diameter for precision small-bore sizing
• HSS construction provides good wear resistance across common workpiece materials
• Bright, uncoated finish suitable for general-purpose reaming applications
• 4-flute straight configuration for smooth, consistent material removal
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank fits standard drill chucks and collet holders

Compatibility

Designed as a standard chucking reamer for use in drill presses, CNC machining centers, lathes, and milling machines equipped with a chuck or collet capable of holding a straight-cylindrical shank at this diameter range.

Installation Notes

Chucking reamers of this size are installed and operated by qualified machinists following standard machine shop practice. Ensure the machine spindle is fully stopped and the tool is securely seated in the chuck or collet before starting the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Never reverse spindle rotation while the reamer is engaged in the workpiece.
