Hertel 72034655 Chucking Reamer 0.465 in Hss 6 Flute

Product Description

The HERTEL 72034655 is a high-speed steel (HSS) chucking reamer designed for precision hole finishing in metal fabrication, machining, and toolroom applications. With a reamer diameter of 0.4650 inches and an overall length of 7 inches, it delivers accurate sizing and smooth bore finishes in through-holes and blind-hole applications. The 6-flute straight configuration distributes cutting forces evenly, reducing chatter and improving surface finish. The bright, uncoated finish is suited for general-purpose ferrous and non-ferrous materials. Licensed machinists, tool-and-die makers, and maintenance technicians are the primary users of this tooling.

This chucking reamer is intended for use in CNC machining centers, manual mills, drill presses, and lathe tailstocks where a straight-cylindrical shank is required. The 1-3/4 inch flute length accommodates standard reaming depths in production and jobshop environments. Right-hand cutting direction is the standard for conventional machine spindle rotation. The bright finish suits operations where cutting fluid provides sufficient lubrication and coating is not required.

Key Features

• 0.4650 inch diameter for precise hole sizing within the 0.4000 to 0.4999 inch decimal range
• 6 straight flutes for even load distribution and improved bore surface finish
• HSS construction provides toughness and good wear resistance for general machining
• Straight-cylindrical shank for direct chuck or collet mounting
• Right-hand cutting direction compatible with standard machine spindle rotation
• Bright uncoated finish suitable for use with cutting fluids on common ferrous and non-ferrous materials

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collet chucks, and machine tool spindles accepting a straight-cylindrical shank.

Installation Notes

Installation is performed by machinists and toolroom technicians. Secure the shank firmly in a properly sized chuck or collet before operation and verify runout with a dial indicator when tight tolerances are required. Ensure the machine spindle is fully stopped before mounting or removing the reamer. Apply an appropriate cutting fluid for the workpiece material to extend tool life and improve finish quality.
