Hertel 2291532 Chucking Reamer Wire 53 Hss 4 Flute

Product Description

The HERTEL 2291532 is a straight-flute chucking reamer designed for precision hole finishing in metalworking operations. Built from high-speed steel (HSS) with a bright, uncoated finish, it delivers accurate sizing on through-holes and blind holes where tight tolerances are required. The reamer carries a wire gauge diameter of No. 53, measuring 0.0595 inches, with an overall length of 2.5 inches and a flute length of 0.5 inches. The straight-cylindrical shank seats cleanly in standard chucks or collets. With 4 right-hand cutting flutes, this tool is suited for low-to-moderate production reaming on manual mills, drill presses, and CNC machining centers.

This chucking reamer is used in general metalworking shops, tool rooms, and production environments where small-diameter hole reaming is performed in ferrous and non-ferrous materials. Its wire gauge sizing makes it a practical choice for reaming to No. 53 specification, a common requirement when fitting pins, dowels, and close-tolerance fasteners in light machining and instrument assembly applications. Installation into standard drill chucks or ER collet holders is straightforward, requiring no special tooling adapters.

Key Features

• Wire gauge No. 53 diameter (0.0595 inches) for precise small-bore finishing
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• 4 straight flutes with right-hand cutting direction for controlled material removal
• Bright, uncoated finish — no coating buildup concerns at small diameters
• Straight-cylindrical shank for secure seating in drill chucks and collets
• Compact 2.5-inch overall length suited for short-reach reaming setups

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet chucks, and floating reamer holders accepting a straight-cylindrical shank in the applicable diameter range.

Installation Notes

Chucking reamers are installed by qualified machinists or toolroom technicians using standard drill chucks or collet systems. Power down and lock out the machine spindle before mounting or removing the reamer. Use appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Do not use this reamer to remove excessive stock — pre-drill or bore the hole to within recommended reaming allowance before final sizing.
