Hertel 2291649 Chucking Reamer Wire 64 Hss Straight

Product Description

The HERTEL 2291649 is a wire-gauge chucking reamer in size 64, designed to finish-ream precision holes to a diameter of 0.0360 inches. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers reliable cutting performance in a compact form factor. The straight-cylindrical shank seats securely in standard drill chucks or collets, making it compatible with drill presses, lathes, and CNC drilling setups. With a right-hand cutting direction and straight flute geometry, this reamer is well suited for finishing through-holes in soft to medium-hardness materials where tight tolerances are required.

This reamer is used in machine shops, toolrooms, and light manufacturing environments for finishing small-diameter holes to close tolerances. At wire size 64 and 0.0360 inches in diameter, it targets applications such as instrument components, small fastener bores, and precision fixture work. The 1-1/2 inch overall length and 1/2 inch flute length suit shallow-hole finishing operations where a compact tool profile is needed. Machinists, tool-and-die makers, and precision manufacturing technicians are the primary users.

Key Features

• Wire size 64 reamer diameter of 0.0360 inches for small-bore precision finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Bright, uncoated finish — ready to use out of the package with no coating buildup risk in tight tolerances
• Straight flute geometry for smooth cutting action in through-hole applications
• Right-hand cutting direction compatible with standard machine spindle rotation
• Straight-cylindrical shank for positive chuck or collet grip

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and CNC equipment equipped with drill chucks or collets accepting a straight-cylindrical shank at this diameter range.

Installation Notes

This reamer is installed and operated by machinists or toolroom technicians. Secure the shank firmly in the chuck or collet before operation and confirm true runout before engaging the workpiece. Always reduce spindle speed relative to drilling and apply appropriate cutting fluid to extend tool life and maintain bore finish. Do not reverse spindle direction during or after the cut, as reverse rotation can damage the cutting edges.
