Hertel 72017908 Chucking Reamer 0.179 in Hss 6 Flute

Product Description

The HERTEL 72017908 is a high-speed steel (HSS) chucking reamer designed to finish-ream drilled or bored holes to a precise 0.1790-inch diameter. With six straight flutes and a right-hand cutting direction, it delivers a clean, accurate bore in ferrous and non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks, collets, or floating holders used on drill presses, lathes, and CNC machining centers. Overall length is 4.5 inches with a 1.125-inch flute length. The bright, uncoated finish makes it well-suited for general-purpose reaming where cutting fluid is applied at the tool.

This reamer is used in machine shops, maintenance facilities, and production environments where hole tolerances require finishing beyond what a drill bit alone can achieve. Typical applications include bearing bores, pin holes, and bushing fits in light manufacturing, toolroom work, and mechanical assembly. It is sized within the 0.1500 to 0.1999-inch diameter range, making it appropriate for small-bore finish work on a wide range of part materials.

Key Features

• 0.1790-inch finished bore diameter for precise hole sizing
• 6 straight flutes for smooth, stable cutting action
• Right-hand cutting direction, compatible with standard machine spindle rotation
• HSS construction provides durability across ferrous and non-ferrous workpiece materials
• Bright, uncoated finish — suitable for use with cutting oils and water-soluble coolants
• Straight-cylindrical shank fits standard chucks and collet holders without adapter sleeves

Compatibility

Designed as a general-purpose chucking reamer for use in drill presses, lathes, and CNC machining centers equipped with standard straight-bore chucks or collet holders sized to accept a straight-cylindrical shank in the 0.1500 to 0.1999-inch diameter range.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the straight-cylindrical shank firmly in the chuck or collet before operation and verify runout with an indicator before cutting. Always apply an appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Pre-drill or bore the hole to proper size before reaming — do not attempt to use a chucking reamer as a primary hole-making tool.
