Hertel 72034614 Chucking Reamer 0.4610 in Hss 6 Flute

Product Description

The HERTEL 72034614 is a straight-flute chucking reamer designed for precision hole finishing in metal fabrication and machining applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this reamer features a 0.4610-inch cutting diameter and a 7-inch overall length. The straight-cylindrical shank seats securely in standard drill chucks and collet holders. With six flutes and right-hand cutting direction, it delivers consistent, smooth bores in ferrous and non-ferrous materials. Machinists and tool-and-die professionals use this reamer for tight-tolerance hole sizing where drill-only results are insufficient.

This chucking reamer is suited for general-purpose reaming on manual mills, drill presses, and CNC machining centers. The 1.75-inch flute length handles typical through-holes and shallow blind holes in production and maintenance machining environments. Its HSS construction supports dry cutting as well as use with cutting fluids. The straight flute geometry is well-matched to materials that produce short, breaking chips, including mild steel, aluminum, brass, and cast iron.

Key Features

• 0.4610-inch cutting diameter for precise hole sizing within the 0.4000 to 0.4999-inch range
• Six straight flutes with right-hand cutting direction for smooth, consistent finishes
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish — compatible with a wide range of cutting fluids
• Straight-cylindrical shank for use in standard drill chucks and collet holders
• 7-inch overall length with 1.75-inch flute length for versatile depth reach

Compatibility

Designed as a general-purpose chucking reamer compatible with standard drill chucks and collet systems accepting a straight-cylindrical shank at the 0.4610-inch diameter specification.

Installation Notes

Installation and use should be performed by a qualified machinist. Secure the reamer firmly in a properly sized chuck or collet before operation and verify runout is within acceptable tolerance before cutting. Always power down and lock out the machine spindle before mounting or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
