Hertel 72290414 Chucking Reamer Wire 41 0.0960 in Hss

Product Description

The HERTEL 72290414 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, it produces accurate, smooth bores at wire size 41, corresponding to a decimal diameter of 0.0960 inches. The reamer features four right-hand cutting flutes and a straight-cylindrical shank for secure chuck mounting on drill presses, lathes, and milling machines. With an overall length of 2.375 inches and a flute length of 0.875 inches, it is sized for small-bore finish reaming where tight tolerances are required. Machinists and toolroom technicians are the primary users of this tool.

This reamer is suited for production and toolroom environments where wire-gauge holes must be brought to a precise finished diameter. It handles ferrous and non-ferrous materials typical of general machining work. The straight flute geometry makes it well-suited for through-hole reaming in shorter-depth bores, and the bright finish keeps the tool ready to run without additional preparation. This is a standard individual unit sold one piece per package.

Key Features

• Wire size 41 diameter at 0.0960 inches for small-bore precision finishing
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Four straight flutes with right-hand cutting direction
• Bright, uncoated finish — no coating removal required before use
• Straight-cylindrical shank seats directly in standard drill chucks and collets
• Overall length of 2.375 inches with a 0.875-inch flute length for controlled reach

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for machine tools accepting a straight-cylindrical shank in the wire size 41 diameter range (0.0500 to 0.0999 inches).

Installation Notes

Chucking reamers of this size are installed and operated by machinists on drill presses, engine lathes, or CNC machines. Power down and de-energize the machine spindle before mounting or removing the reamer. Secure the straight-cylindrical shank firmly in a chuck or collet to prevent runout. Always ream at appropriate spindle speed and feed rate for the workpiece material — consult standard machining data references for wire-gauge reamer recommendations.
