Hertel 72294465 Chucking Reamer Wire 46 0.0810 in Hss

Product Description

The HERTEL 72294465 is a high-speed steel (HSS) chucking reamer designed to finish-ream holes to a precise wire-gauge size 46 diameter of 0.0810 inches. With a 4-flute spiral configuration and right-hand spiral direction, this reamer delivers consistent stock removal and a smooth bore finish in through-holes and blind holes. The straight-cylindrical shank seats securely in standard drill chucks and collets. Overall length is 2.125 inches with a flute length of 0.75 inches. This tool is suited for machining operations requiring tight-tolerance hole finishing in steel, aluminum, brass, and similar materials. It weighs 0.1 pounds.

This chucking reamer is used in machine shop environments, production drilling operations, and maintenance applications where accurate hole sizing is required. The wire-gauge 46 designation makes it appropriate for finishing small-diameter holes where standard fractional or letter-size reamers do not cover the required tolerance. It is compatible with manual drill presses, CNC machining centers, and engine lathes using standard chuck or collet toolholding. Both production machinists and toolroom technicians regularly specify this type of reamer for precision hole finishing work.

Key Features

• Wire size 46 diameter at 0.0810 inches for precise small-bore finishing
• 4-flute spiral geometry with right-hand spiral direction for smooth material removal
• HSS construction provides durability across a range of ferrous and non-ferrous materials
• Straight-cylindrical shank for use in standard drill chucks and collet holders
• Compact 2.125-inch overall length suited for tight-clearance setups
• 0.75-inch flute length appropriate for shallow through-hole and blind-hole applications

Compatibility

Designed as a standard chucking reamer for use in drill presses, lathes, and machining centers equipped with drill chucks or collets that accept a straight-cylindrical shank in the small-diameter range.

Installation Notes

This reamer is installed and operated by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank firmly in a drill chuck or collet before use, and verify concentricity to minimize runout. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality. Never use a chucking reamer to remove excessive stock; pre-drill or bore the hole to within recommended reaming allowance before finishing.
