Hertel 4599932 Chucking Reamer 12.00mm Cobalt Steel

Product Description

The HERTEL 4599932 is a chucking reamer designed for precision hole finishing in metal fabrication, machining, and toolroom applications. Built from cobalt steel, this right-hand cutting reamer delivers the hardness and heat resistance needed when working through tough alloys. It carries a 12.00mm (0.4724 inch) reamer diameter, an overall length of 8 inches, and a 2-inch straight flute length. The bright, uncoated finish keeps tolerances consistent and allows operators to inspect the cutting edges easily. Machinists and tool-and-die professionals install this style of reamer to bring bored or drilled holes to a precise final diameter with a clean, smooth finish.

This chucking reamer is suited for use in CNC machining centers, manual lathes, and drill presses where a straight-cylindrical shank can be held securely in a drill chuck or collet. It handles sizing holes in steel, cast iron, and similar ferrous materials where dimensional accuracy is critical. The straight flute geometry makes it appropriate for through-holes and shorter blind-hole applications. This is not configured as a dowel-pin reamer or an over/under size reamer, so it is intended for standard nominal-diameter finishing passes.

Key Features

• 12.00mm (0.4724 inch) diameter for precise hole sizing in the 0.4000 to 0.4999 inch range
• Cobalt steel construction provides elevated heat and wear resistance compared to standard HSS
• Straight flute design suits through-holes and short blind-hole finishing
• Right-hand cutting direction compatible with standard spindle rotation
• Bright, uncoated finish allows easy visual inspection of cutting edge condition
• Straight-cylindrical shank seats securely in drill chucks and collets

Compatibility

Designed as a standard chucking reamer for use in any machine tool equipped to hold a straight-cylindrical shank, including CNC machining centers, lathes, and drill presses requiring a 12.00mm nominal reamer diameter.

Installation Notes

A licensed machinist or qualified toolroom technician should install and operate this reamer. Always disengage and lock out power to the machine before mounting or removing tooling from the spindle. Secure the straight-cylindrical shank firmly in the chuck or collet to the appropriate holding depth before operation. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain hole-finish quality.
