Hertel 72035454 Chucking Reamer 0.5450 in Hss Straight Flute

Product Description

The HERTEL 72035454 is a straight-flute chucking reamer designed for precision hole finishing in metalworking applications. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer delivers accurate sizing and smooth bore surfaces in a wide range of ferrous and non-ferrous materials. It features a 0.5450-inch cutting diameter, an 8-inch overall length, and a 2-inch flute length, making it well suited for through-hole and blind-hole reaming operations requiring tight dimensional tolerances. The straight-cylindrical shank allows secure clamping in standard drill chucks, collets, or floating holders.

This chucking reamer is intended for use in machine shop environments, job shops, and production facilities where controlled material removal and consistent hole finish are required. It is suited for CNC machining centers, drill presses, lathes, and manual mill setups. The right-hand cutting direction and 8-flute configuration produce fine surface finishes and support steady chip evacuation during through-hole reaming passes. Machinists and toolroom technicians are the primary users of this tool.

Key Features

• 0.5450-inch reaming diameter for precise hole finishing within the 0.5000 to 0.6999-inch diameter range
• 8 straight flutes for smooth cutting action and consistent surface finish
• Right-hand cutting direction compatible with standard machine spindle rotation
• High-speed steel (HSS) construction provides toughness and wear resistance across common workpiece materials
• Bright, uncoated finish suitable for use with cutting fluids or dry cutting where HSS is appropriate
• Straight-cylindrical shank for direct clamping in chucks, collets, or floating reamer holders

Compatibility

Designed as a standard chucking reamer for use in any machine tool capable of accepting a straight-cylindrical shank tool in the appropriate diameter range.

Installation Notes

Installation and operation of this reamer should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool is securely clamped in a properly sized chuck or collet before beginning any operation. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Always pre-drill or bore the hole to the correct allowance before reaming to avoid overloading the flutes.
