Hertel 72034747 Chucking Reamer 0.4740 in Hss 6 Flute

Product Description

The HERTEL 72034747 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer holds a cutting diameter of 0.4740 inches across 6 right-hand flutes. The straight-cylindrical shank seats securely in drill chucks, collets, and reamer holders on manual lathes, drill presses, and CNC machines. With an overall length of 8 inches and a 2-inch flute length, the tool reaches moderate-depth bores while maintaining rigidity. It is intended for machinists and toolroom professionals who need repeatable, close-tolerance hole sizing in ferrous and non-ferrous materials.

This chucking reamer is suited for production and toolroom environments where drilled holes require final sizing to a consistent finish diameter. The 0.4740-inch diameter places it in the 0.4000 to 0.4999 inch reamer diameter range, making it appropriate for finish-reaming operations on steel, cast iron, aluminum, and similar machinable materials. The right-hand cutting direction is standard for conventional machine reaming setups. It ships as a single unit and is applicable in both job-shop and light production scenarios where HSS tooling meets the speed and feed requirements of the workpiece material.

Key Features

• 0.4740-inch cutting diameter for close-tolerance hole finishing
• 6 straight flutes with right-hand cutting direction for smooth material removal
• HSS construction provides toughness and regrindability for toolroom use
• Bright, uncoated finish suitable for use with cutting fluids on a wide range of metals
• Straight-cylindrical shank compatible with standard drill chucks and collet holders
• 8-inch overall length with 2-inch flute length for moderate-depth bore applications

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, manual lathes, and CNC machining centers equipped with standard straight-bore chuck or collet toolholding systems accepting a straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom professional. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation, and verify runout before cutting. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Consult machine manufacturer feed and speed guidelines for HSS reaming; excessive speed without adequate lubrication can cause premature tool wear or dimensional inaccuracy.
