Hertel 72034705 Chucking Reamer 0.47 in Hss 6 Flute

Product Description

The HERTEL 72034705 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal machining applications. With a 0.4700-inch cutting diameter and six straight flutes, it delivers consistent bore sizing and smooth surface finishes in through-holes and blind holes alike. The straight-cylindrical shank seats securely in a drill chuck or machine collet. At 7 inches overall length with a 1-3/4-inch flute length, this reamer is suited for light-to-moderate stock removal in finishing operations. The bright, uncoated finish is standard for general-purpose HSS tooling used across a wide range of ferrous and non-ferrous materials.

This chucking reamer is used in manual drill presses, CNC machining centers, lathes, and milling machines where a reamed hole tolerance is required after drilling. It is appropriate for job shops, maintenance machinists, and production environments handling general metalworking tasks. Right-hand cutting direction is standard for conventional spindle rotation. The 0.4700-inch diameter falls within the 0.4000-to-0.4999-inch range, targeting holes that require close-tolerance finishing prior to press-fit or slip-fit assembly.

Key Features

• 0.4700-inch cutting diameter for precise hole finishing in the 0.40-to-0.4999-inch range
• 6 straight flutes with right-hand cutting direction for smooth, consistent material removal
• HSS construction provides adequate hardness for general-purpose ferrous and non-ferrous machining
• Bright, uncoated finish — standard for HSS reamers used across varied material types
• Straight-cylindrical shank is compatible with standard drill chucks and machine collets
• 7-inch overall length with 1-3/4-inch flute length suits typical through-hole and shallow blind-hole operations

Compatibility

Designed as an OEM-style chucking reamer for use in any machine tool accepting a straight-cylindrical shank in the corresponding collet or chuck size.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations. Power down and lock out the machine spindle before mounting or removing the reamer. Secure the straight-cylindrical shank fully in the chuck or collet to the recommended grip depth before operation. Use appropriate cutting fluid for the workpiece material to maximize tool life and hole finish quality.
