Hertel 2291680 Chucking Reamer Size 68 Hss Straight Flute

Product Description

The HERTEL 2291680 is a wire gauge size 68 chucking reamer designed to produce precise, finished holes to a diameter of 0.0310 inches. Constructed from high-speed steel (HSS) with a bright, uncoated finish, this tool provides reliable cutting performance in a wide range of metals and engineering materials. The straight-cylindrical shank seats securely in standard drill press or lathe chucks, and the three-flute straight geometry delivers clean, accurate hole sizing. With an overall length of 1.375 inches and a flute length of 0.5 inches, this reamer is built for small-diameter finish reaming where dimensional accuracy is critical.

This reamer is suited for machine shop, toolroom, and production applications where wire gauge holes must be held to close tolerances. It is commonly used in drill press, lathe, or milling machine setups when hand reaming is not sufficient for the required finish. The compact size and straight shank make it well-suited for short-reach, small-bore finish passes in fixtures, jigs, and precision components across metalworking, instrument manufacturing, and light industrial environments.

Key Features

• Wire gauge size 68, 0.0310-inch diameter for precise small-bore finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright, uncoated finish — no coating interference on critical diameter tolerances
• Three-flute straight configuration for accurate, smooth hole sizing
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank for secure chuck retention in drill press, lathe, or mill setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, lathe tailstock chucks, and milling machine setups requiring a straight-cylindrical shank in wire gauge size 68.

Installation Notes

A licensed machinist or trained toolroom professional should install and operate this reamer in appropriate machine tool spindle setups. Secure the straight-cylindrical shank firmly in the chuck before beginning the operation, and ensure the workpiece is rigidly fixtured to prevent deflection at this small diameter. Always reduce spindle speed relative to larger reamers when working at 0.0310-inch diameter, and apply appropriate cutting fluid to extend tool life and improve surface finish. Never attempt to use a chucking reamer for hand reaming without a proper guide fixture.
