Hertel 2291656 Chucking Reamer Size 65 0.0350 in Hss

Product Description

The HERTEL 2291656 is a straight-flute chucking reamer designed for precision hole finishing in wire size 65 applications. Ground from high-speed steel (HSS) with a bright, uncoated finish, this reamer produces accurate, smooth bores at a nominal diameter of 0.0350 inches. The straight-cylindrical shank is compatible with standard drill chucks and collet holders. With an overall length of 1.5 inches and a flute length of 0.5 inches, this is a compact tool suited for close-tolerance finishing work in thin stock or shallow through-holes. Right-hand cutting direction is standard. Machinists and tool-and-die professionals reach for this style of reamer when drilling alone cannot hold the required finish or dimensional tolerance.

This reamer is applied in precision machining environments where fine wire-gauge holes require a consistent finished diameter. Typical use cases include instrument components, small mechanical assemblies, jig-and-fixture work, and any application requiring a controlled bore in the sub-0.05-inch diameter range. The straight flute geometry works well in most materials including mild steel, aluminum, brass, and plastics where chip evacuation is not a limiting factor.

Key Features

• Wire size 65 designation with a decimal diameter of 0.0350 inches for precise hole sizing
• High-speed steel (HSS) construction provides hardness and wear resistance for general machining applications
• Bright, uncoated finish — no coating buildup that could affect critical bore dimensions at this small diameter
• Straight flute geometry simplifies re-sharpening and suits a broad range of workpiece materials
• Straight-cylindrical shank seats securely in drill chucks and precision collet systems
• Right-hand cutting direction; compact 1.5-inch OAL fits confined setups and short-travel spindles

Compatibility

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

Installation Notes

This reamer is installed and used by machinists and toolroom technicians. Always secure the workpiece firmly before reaming; never attempt to ream a hole that has not been pre-drilled to the appropriate undersize. Use cutting fluid appropriate to the workpiece material to extend tool life and improve finish quality. Inspect the shank and flutes for damage before each use; a chipped or worn reamer at this small diameter can produce out-of-tolerance bores.
