Hertel 72295314 Chucking Reamer 31/64 in Hss 6 Flute

Product Description

The HERTEL 72295314 is a straight-shank chucking reamer designed for precision hole finishing in metal and manufactured from high-speed steel (HSS) with a bright, uncoated finish. It carries a 31/64 inch (0.4844 inch decimal) diameter, a 2 inch flute length, and a 5-7/8 inch overall length. Six right-hand spiral flutes remove material efficiently while delivering a smooth, accurately sized bore. The straight-cylindrical shank seats directly into drill press or lathe chucks. This tool is intended for use by machinists and tool-and-die professionals who require close-tolerance hole sizing in production or maintenance environments.

The 72295314 is suited for reaming operations on ferrous and non-ferrous workpieces in machine shop, maintenance, and general manufacturing settings. Its HSS construction handles moderate cutting speeds without the added cost of coated or carbide tooling, making it a practical choice for job-shop and toolroom applications where a range of materials and run lengths are encountered. The bright finish allows easy visual inspection of cutting edge condition during use.

Key Features

• 31/64 inch (0.4844 inch) reamer diameter for close-tolerance hole sizing
• 6 right-hand spiral flutes for smooth chip evacuation and consistent finish
• HSS tool material provides toughness across a range of workpiece materials
• Bright, uncoated finish allows straightforward edge-condition inspection
• Straight-cylindrical shank for direct chuck or collet mounting
• 5-7/8 inch overall length with 2 inch flute length for standard-depth applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and milling machines equipped with a straight-bore chuck or collet capable of accepting a straight-cylindrical shank in the appropriate diameter range.

Installation Notes

A licensed machinist or qualified tool operator should install and operate this reamer. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify runout with a dial indicator when close tolerances are required. Always power down and lock out the machine spindle before changing or inspecting tooling. Do not force the reamer into an undersized hole; the bore should be pre-drilled or bored to the appropriate stock-removal allowance before reaming.
