Hertel 2412302 Chucking Reamer 15/32 in Cobalt Steel 6 Flute

Product Description

The HERTEL 2412302 is a cobalt steel chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 15/32 inch (0.4688 inch decimal) diameter and a 7 inch overall length, this reamer delivers accurate, consistent bore sizing in both manual and CNC setups. The 6-flute spiral design with right-hand cut provides smooth chip evacuation and a fine surface finish. The bright, uncoated finish suits general-purpose ferrous and non-ferrous materials. Machinists, tool-and-die workers, and production shop personnel use this reamer as a finishing tool to bring drilled or bored holes to tight dimensional tolerances.

The 2412302 is suited for machine shop production work, maintenance and repair operations, and toolroom applications requiring precise hole sizing in the 0.4000 to 0.4999 inch diameter range. The straight-cylindrical shank mounts directly into standard drill chucks, collet chucks, or machine spindles on drill presses, lathes, and machining centers. The 1-3/4 inch flute length accommodates typical shallow-to-moderate depth finish reaming passes in ferrous and non-ferrous workpieces.

Key Features

• 15/32 inch (0.4688 inch decimal) reamer diameter for precise hole finishing
• Cobalt steel construction for increased hardness and heat resistance compared to standard high-speed steel
• 6-flute spiral, right-hand cut geometry for smooth chip flow and improved surface finish
• 1-3/4 inch flute length suits shallow-to-moderate depth reaming applications
• Straight-cylindrical shank for direct mounting in drill chucks, collet chucks, and spindles
• Bright, uncoated finish for general-purpose use across a range of workpiece materials

Compatibility

Designed as an OEM-style chucking reamer for use in drill presses, lathes, and machining centers equipped with standard drill chucks or collet chuck systems accepting a straight-cylindrical shank in the 0.4000 to 0.4999 inch diameter class.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer from the chuck or collet. Verify proper chuck or collet grip on the straight-cylindrical shank before running the spindle. Use appropriate cutting fluid for the workpiece material, and never exceed the rated speed range for cobalt steel tooling in the given material class.
